Orbital height - In theory, you could go as low as double (Kerbin radius + atmospheric height), or 740km altitude, but the placement would have to be perfectly at 120 degrees phase angle. Rather than opening instantly, the solar panels will appear in the queue, scheduled to open after the delay. What does 'They're at four. Relay Satellites are used to communicate with the Kerbal Space Center without the need for a direct connection to it. Connect and share knowledge within a single location that is structured and easy to search. Launching a satellite into orbit means it will, sooner or later, end up on the far side of the planet. Use mod filters to select craft that; will work With selected mods. Otherwise this scheme is resistant to placement errors. The second one uses Coatl Aerospace antennas (he has lots of useful antennas) and a bunch of Near Future parts, Solar/Electrical/Construction, and I think some Contares parts too. Once the solar panel command(s) are in the queue, type 0 followed by enter to reset the delay (otherwise ALL your commands will have a delay). With the fact that each antenna has a limited range, this makes relay satellites a necessity for almost every interplanetary mission[citation needed]. One between Kerbin and Duna with six satellites. Valve Corporation. Minmus Relay Satellites : r/KerbalAcademy - Reddit Improving the copy in the close modal and post notices - 2023 edition, New blog post from our CEO Prashanth: Community is the future of AI, Screenshot of the Week #89 [Submissions Closed, Vote Now! It looks more or less stock to me, although on close inspection it has some fiddly bits I can't quite identify. Given the nature of orbits, this wouldnt be too much of a problem since the satellite would come back around again, except that on that first crucial launch, you need control to circularize your orbit. In the window that opens, select Mission Control to make it the antennas target. The best answers are voted up and rise to the top, Not the answer you're looking for? Two satellites with a single 100g relay dish each can always talk from Jool to Kerbin, and a probe with a 100g direct link can always talk to KSC if it has line of sight. 2023 Take-Two Interactive Software, Inc. So, for four satellites, they should be spaced about 46 days apart. KSP 1.2: How To Create a Geostationary Relay Network How to achive a highly eccentric polar orbit around the sun oriented orthogonal to the ecliptic? Intro to CommNet Part 2: How to Make a Relay Network - YouTube rev2023.4.21.43403. Since electricity isn't consumed when a vehicle isn't controlled by the player, electric charge storage and generation isn't required. You cannot paste images directly. Does the 500-table limit still apply to the latest version of Cassandra? Click GRD+ to tell the ship to face prograde (at least, until it gets out of the atmosphere), then click EXEC to tell it to execute the maneuver node. These are landers, but it works just as well with satellites. Could someone explain that as well? Doesn't save mass, but it does allow for SLIGHTLY longer satellites. kerbal space program - How to build a satellite network around Kerbin However many Life Support mods will allow power drain from inactive crafts. That is, if this calculation shows you should launch every 550 days for a 100 days period target orbit, of course you should modulo that to a 50 days delay. Then pick the attitude command of your choice: press the SAS key, or click KILL to kill rotation, or click GRD+ to hold prograde (if you already have an active GRD+ command, you may have to click twice, then cancel the command labeled mode: off). It assumes you have not yet established a comsat network, so that the only connection of interest is a direct link between the satellite and the Kerbal Space Center (KSC). Multi-Satellite Launches - Kerbal Space Program Forums Communication links only work while the satellite has power, so if you fail to deploy the panels before the satellite goes out of contact, you might not be able to recover it one orbit from now. For missions to high orbits (or just for practice before you send up a full-fledged comsat), you may wish to include one of the other antennas in your design. Researching Electrics, which unlocks solar panels, is recommended but not required. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. Privacy Policy. Hello- I thought in this play-through it would be fun to set up my own relay satellite network. Use RA-100 relays. Note that "What you can talk to" depends on the power of BOTH vessels (or the vessel and the tracking station), so if both vessels have the same power, the rated power is the range they can talk. (I recommend the decoupler be set to 0 force so your orbits don't change when you detach.) It's reasonably accurate over close-ish values to take the average, but the actual math is the square root of (the first vessel's power x the second vessel's power). All RemoteTech antennas are safe to use above 35 km, so you should be able to deploy the antenna while still in line of sight to KSC. Equatorial triangle orbit above 210km. Espaol - Latinoamrica (Spanish - Latin America), http://steamcommunity.com/sharedfiles/filedetails/?id=780126583, http://steamcommunity.com/sharedfiles/filedetails/?id=780855597, http://steamcommunity.com/sharedfiles/filedetails/?id=780855847. If you put the relays on opposite sides of a highly elliptical polar orbit, you should have very little loss of signal time. If you have the Comms DTS-M1, right-click on it while on the launchpad, then click the button marked No Target. You can also - if you don't want to use fairings and don't mind a draggy front-end on your rocket (hint: you should mind a draggy front-end on your rocket) you can also radially mount the satellites. And for total coverage do triple relay sat launches for the Mun and Minmus. My rule of thumb is generally, one dish is good, two is better, if I have to do more than 4 I might want to look at sending up two probes instead. Select mods using text field above and KerbalX will find craft that use those mods. Adding additional relay rings around Kerbol should also help with coverage. Use RA-2 relays. Or you can just leave it where it is, happily beeping away. Yeah, I like parts, so I have mostof them. I was sort of inspired to do this by how the Chinese Chang'e 4 lander uses the Queqiao relay satellite to communicate with Earth from the far side of the Moon. You then need to have (for 8 satellites) p/8 = t*(p/k - 1) with t the time between launches. If you dont want the full Life support experiance make sure you disable food/water/o2 ect in the mod options in the menu system. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. Relay antennas are exclusively non-foldable, so has anyone come up with a way to fit more than one relay satellite onto a rocket without using huge parts? Send a couple small relay satellites with your probe. Arqade is a question and answer site for passionate videogamers on all platforms. The final queue should look something like this picture (the Toggle SAS command is optional). The best way to get multiple sats in one launch is to use the "Interstage Nodes" option on the fairings, which will let you attach multiple stacked payloads without them touching. Yes, that's how combine works. 184 / (4*0.568) = 81 days. New comments cannot be posted and votes cannot be cast. Launch however you usually do. Without a connection to the Kerbal Space Center, an unmanned probe will either not be able to function, or will be in limited probe control, depending on your settings for the game. Transmission When the transmit button is pressed while reviewing experiment results, an antenna will automatically deploy to perform a transmission and then retract after completion. A set of twelve evenly spaced relays at around 25,000,000km. So there, the separation will be of p*t/k - t, but "forward". Is there a generic term for these trajectories? If you are using the flight computer to get into orbit, the computer will turn off attitude control at the end of the burn, which will leave the satellite slowly tumbling. There are two ways to avoid this, depending on your play style: following a steep launch path or using the flight computer. 2 Satelites in matching orbits in opposite ends of eachother. It only takes a minute to sign up. Will keep at it, now I've got a better understanding of CommNet! Has depleted uranium been considered for radiation shielding in crewed spacecraft beyond LEO? Unexpected uint64 behaviour 0xFFFF'FFFF'FFFF'FFFF - 1 = 0? Then open each panel by right-clicking or using an action group, as in normal KSP. Period of target orbit p = 184 days Really like the design of your quad-probe. I did a six-lander Mun invasion once, with landers very similar to what you see above stacked six high with stack separators between each and an orbital maneuvering stage with lots of Dv for multiple plane changes. Tutorial - First Satellite - GitHub Pages And so far, signal will always use the best path available. With a 2G antenna on probe, this should give you complete coverage within planetary spheres of influence. Kerbin, Mun and Minmus block one satellite each, or. There is also an advanced difficulty setting where you don't have stations all over Kerbin but only have the KSC. Relay satellites and probe control :: Kerbal Space Program General Was Aristarchus the first to propose heliocentrism? > With proper resonance, you are in a mapping orbit and can complete grab/temp scans above x contacts without fuel burn. load your currently installed mods. Mun/Minmus occlusion: All the satellites can get occluded when either. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. And what on the Probe around the Mun? How can I control PNP and NPN transistors together from one pin? It must be placed where it has a connection to the rest of the CommNet network, either it being a ground station on Kerbin or another Relay satellite. Sort by votes Sort by date Equatorial triangle orbit above 700km. If total energies differ across different software, how do I decide which software to use? how to plan pre-network missions around your limited line of sight to KSC. Relays Not Working :: Kerbal Space Program General Discussions What are the advantages of running a power tool on 240 V vs 120 V? Polar triangle orbit above 700km. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. 3 Satellites in an equal orbit forming an equalateral triangle with eachother. Making three trips per body seems like a complete waste of time and resources when these satellites weight so little. Did the Golden Gate Bridge 'flatten' under the weight of 300,000 people in 1987? I have bi-coupler and tri-coupler versions also. Arqade is a question and answer site for passionate videogamers on all platforms. You can do this either by right-clicking on the antenna and clicking activate, or by binding it to an action group in the VAB. How to combine several legends in one frame? Which gives t = p/(8(p/k - 1)). You probably. If your satellite will never go above 150 km, this is more than adequate any time you have a line of sight to Mission Control, you will be in range. About 3000g orbiting outside Minmus. You can also slightly rotate the two bottom satellites so they are more "next to" each other than facing off. Any clues? The only important thing is that the orbital periods of all three be the same, as the larger the difference, the sooner they will get out of position.

SpanishInquisitor27 4 yr. ago Equatorial triangle orbit above 320km. Left: A comlink-friendly ascent path. This video tutorial demonstrates how to build, launch and set up a relay satellite network in KSP. What risks are you taking when "signing in with Google". "beep beep beep beep" - Leonard Nimoy, using the flight computer to get into orbit, how to keep control of unmanned rockets from liftoff to orbit. So unless you are talking to Dres that is probably overkill, and depending on what dish those are they might not reach out to Jool. Launch. With a 15G antenna, you get much better deep space coverage. Clear editor. I'm used to the direct communication system, but when I got the Breaking Ground expansion I tried to make some deep-space relays for rovers, and instantly ran into some problems. Period of Kerbin orbit k = 426 days. So I am trying to build an efficient network of relay satellites to allow me to communicate with spacecraft exploring the far sides of the Mun and Minmus. This can be easily solved with the addition of one more satellite (at a later point), just make sure no two satellites line up when Kerbin blocks one of them. So, for example, if we have three satellites 120 degrees apart, adding the fourth halfway between two of them is bad, as 120+60=180 and it can still get occluded. These relays are for connecting with deep space probes. Altitude depends on moon (500km for Laythe, 300km for Vall, 600km for Tylo, 65km for Bop and 44km for Pol). When do relay satellites kick in? :: Kerbal Space Program General Number of satellites - Three satellites are enough to form a complete ring around Kerbin. Relay sat. If an antenna can connect to the KSC (e.g. Will I need to set up a relay Network to do this? Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. The DP-10 is unique among RemoteTech antennas in that it is automatically switched on at mission start, so you dont need to do any fine-tuning on the pad. I like to stack multiple satellites per level, as shown below (those are smaller sats of course, but the same concept applies). Browse other questions tagged, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site. You can get more details in this KSP forum post, which takes it from this research paper (paywall). Satellite exploding while in transfer orbit. Once you are coasting to apoapsis, set a maneuver node to represent the final burn to reach orbit. Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Although I am checking in version 1.5, so they might have new skins in later versions. Check that the Delay (+ signal) display reads one minute. I also tend to make a network with RA-2 relays around a planet then a single larger relay in a highly elliptical polar orbit - so rovers or whatever talk to the nearest small relay, which bounces through the large relay back to Kerbin, rather than trying to make a network of RA-15 or RA100 relays in a single launch. Is there a way to calculate my launch interval (knowing how many satellites in the constellation, orbital period, and apoapsis/periapsis) so I wind up with an equally spaced constellation? In order to get a separation of p/4 (4 satellites evenly spaced on the orbit of period p), you need to have p/4 = t*(1 - p/k) with t the time between launches. a normal antenna can connect to a relay antenna or the KSC directly. Bear in mind that when it's acting as a relay, it's running on rails (unless you happen to have your currently-piloted ship parked right next to it, inside the physics bubble), which means that it doesn't actually use up electricity while it's running. For more information, please see our Pasted as rich text. How to build a satellite network around Kerbin which guarantees full coverage? Basically, for a larger target orbit, you have to divide your initial assumption (of splitting the target period in 8 equal chunks) by p/k - 1 (which is then positive). Showing 1 - 13 of 13 comments I got the same answer from the KSP fora, but with minimal explanation of the underlying math. Please note that this page is incomplete, and requires the help of the community. But adding it 40 degrees away is OK and will prevent occlusion from Mun/Minmus.). It consists of three co-orbital satellites, 120 degrees apart. So the actual separation, in time, is actually t - t2 = t - t*p/k = t*(1 - p/k). By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. You could launch them one at a time from Kerbin and do all kinds of shenanigans to get them into a common orbit (say, 100,000 km above Minmus) at 120-degree intervals along that shared orbit. How to build a Satellite Network? - KSP1 Gameplay Questions and Polar triangle orbit. Kerbin has done a portion t/k of its orbit, which corresponds, for a satellite on target orbit, of a advance of t2 = p*t/k. As for any KSP probe, you will need a probe core, a battery, and (once you have the tech) solar panels. 1 Relay Satelite in Stationary orbit in the Center of the light side of Minmus. I've just started playing 1.2, loving it so far! Squad might want to make that necessity a little more clear. If the satellites are high up the spots will be really small, but any terrain irregularities close to them will easily block the signal. Relay Satellites give the function for other Probes to stay connected to the Kerbal Space Center without having the requirement to be in the line of Kerbin, or the range. The satellite is on the same side of the mun as the probe and has full signal from Kerbin. Learn more about Stack Overflow the company, and our products. However, I was wondering, in what circumstances does your vessel bounce its signal off a relay satellite? Polar triangle orbit above 130km. You usually put a relay antennae in orbit of a planet so you can bounce a signal from the KSC to a place where it normally would not be able to reach, such as the side of the moon opposite kerban where line of sight is blocked by the moon or on a distant planet where the signal cannot normally reach. With that option on, each probe requires either direct line of sight to the KSC or to a communication satellite which has a connection. All rights reserved. > I like to use my polar relay as a synchronization timer in case my Draim constellation desynchronizatizes. :D. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. To control a probe or satellite from the ground, you need a reliable communications link over which to send commands to mission control. Blind spots: Having a ring of satellites leaves blind spots on the surface (poles in case of equatorial ring). Could a subterranean river or aquifer generate enough continuous momentum to power a waterwheel for the purpose of producing electricity? When I first looked at it I initially thought that was actually a carrier for like 6 individual relay sats, and that would be very cool. Well actually kinf of yes. Note: Your post will require moderator approval before it will be visible. Creating a satellite Start with an RC-001S probe core Underneath, add a reaction wheel and a few z-1k battery banks Add some Gigantor-XL solar panels around the outside. The orbital altitude must be greater than the radius of the body you are orbiting. What "benchmarks" means in "what are benchmarks for?". All trademarks are property of their respective owners in the US and other countries. (A spacecraft consisting of a pilot would not be affected.) This satellite is out of control . Connect and share knowledge within a single location that is structured and easy to search. Use RA-2 relays. If you have an antenna other than the DP-10, you will need to activate it in flight. A Relay Satellite is a Probe orbiting a Celestial body that serves the function of creating a Relay Network. The gold parts are Procedural Parts batteries. Such a formation will provide coverage on all of Kerbin's surface and cannot get fully occluded by Mun/Minmus. KerbalX - KSP Craft Sharing Simplified and our With update 1.2, you need to make sure that probes always have a communication link to Kerbin. so a relay antenna can used to connected multiple satelites and the KSC for example normal antenna - relay - relay - relay - KSC -> works relay - normal antenna - relay - KSC -> dont work #3 321 Oct 29, 2016 @ 10:12am So.. Each additional dish adds less power than previous dishes, so if those are all RA-2 dishes for example with a range of 2 GM each, you could replace all of them with one RA-15 relay antenna with a range of 15 gm and probably wind up with a very comparable probe that has 1/10th the payload mass. Every time it passes over KSC, you can send or schedule more commands. Satellites are not connecting to each other There are times where i have my probes not connected to KSC, bit they are in range with other probes. 3 Satellites in an equal orbit forming an equalateral triangle with eachother, 1 Relay Satelite in Stationary orbit in the Center of the light side of Minmus, 2 Satelites in matching orbits in opposite ends of eachother. Polar triangle orbit above 210km. However, no matter how much the distance between the satellites, the transmission will ultimately end up at Kerbin, or else the transmission will not be established at all. By the time 46 days passed after launching the first satellite, the periapsis moved ahead a bit and the second satellite was ~26 days behind the first. This tutorial covers the basics of launching a standalone satellite in RemoteTech. The pod is a little tiny 1-kerbal unit that is perfect for small landers from one of the Umbra Space Industries mods. Reddit and its partners use cookies and similar technologies to provide you with a better experience. Can't remember if those or stock or not. Its just a matter of being careful. Polar triangle orbit above 60km. Type a delay that corresponds to just after the orbit insertion is finished (any attitude commands sent during the burn will be ignored). So four 15G communication dishes on one sathave a range of 42 gm, which if I recall covers everything but Jool and Eeloo. Calculate Satellite Constellation Launch Interval, Improving the copy in the close modal and post notices - 2023 edition, New blog post from our CEO Prashanth: Community is the future of AI, Screenshot of the Week #89 [Submissions Closed, Vote Now!]. Some trial and error may be necessary if youre used to shallower launches, but the traditional 45 ascent path should work. Method 2: Flight Computer. Type 1m (for one minute, or whatever delay you think you need to be clear of that pesky air) in the lower right text box, then press enter. Use RA-2 relays. Which ability is most related to insanity: Wisdom, Charisma, Constitution, or Intelligence? I figure I could add 20 days to the launch window (launch every 66 days). It assumes you have not yet established a comsat network, so that the only connection of interest is a direct link between the . Helpful Linkshttps://wiki.kerbalspaceprogram.com/wiki/Comm. https://wiki.kerbalspaceprogram.com/index.php?title=Tutorial:Setting_up_a_CommNet_system&oldid=99428, Underneath, add a reaction wheel and a few z-1k battery banks. Considering circular orbits only (or close enough), the thing is that when you launch 46 days apart, Kerbin goes 46 days forward, reducing the actual interval between each satellite (if your target orbit is smaller, otherwise it increases it). You only really need one, back it up with a few smaller much lower-power relay sats in close orbit around Kerbin to ensure global coverage. Were fuel efficiency your only concern, you would want a long, flat launch path to build up speed, and some mods (particularly Ferram Aerospace Research) encourage this. Cookie Notice is there such a thing as "right to be heard"? If you want probes at the poles, one solution is to just have another ring in a polar orbit. I have too many KSP screenshots. Thanks, found the answer. The HG-5 is a folding relay antenna, it's just not very strong. In fact, all you have to do is divide the period of the target orbit by the number of satellites times the absolute value of the factor 1 - p/k. Let's ignore occlusion by Mun and Minmus for now and focus only on what it takes to not get blocked by Kerbin. Resonant Orbit Calculator (Kerbal Space Program) - meyerweb.com I tried launching one satellite every 46 days, but that didn't work. I suppose I could launch all of my satellites at (about) the same time (they're too big to practically launch as a single vessel especially eight of them) and use the calculator to space them out. Polar triangle orbit above 138km. Privacy Policy. But I find it makes sense to put fewer sats on the top, so the fairing can taper around them. Equatorial triangle orbit above 13km. Now warp to your Ap and deploy the first relay. Relay Satellite - Kerbal Space Program Wiki Valve Corporation. Factor of division = 1 - 184 / 426 = 0.568. This satellite is in visual range of KSC. Espaol - Latinoamrica (Spanish - Latin America), https://en.wikipedia.org/wiki/Tundra_orbit. Display as a link instead, I have decided I want to launch multiple scientific hopper probes to Minmus, however in order to do this I will need to relay the probes through a satelite in order to mauntain control, these probes are intended to go to all of the biomes if Minmus including the poles, I have considered a few different satellite configurations for this and I would like to know what the benefits of each of them are. Right: The position of a satellite in an 80km orbit just before it loses line of sight with KSC. Polar triangle orbit above 250km. I was sort of inspired to do this by how the Chinese Chang'e 4 lander uses the Queqiao relay satellite to communicate with Earth from the far side of the Moon.
