These relays are for connecting with deep space probes. Now warp to your Ap and deploy the first relay. Equatorial triangle orbit above 700km. 1 Relay Satelite in Stationary orbit in the Center of the light side of Minmus. 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. r/KerbalSpaceProgram on Reddit: KSP Relay Network Guide 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. Intro to CommNet Part 2: How to Make a Relay Network - YouTube Connect and share knowledge within a single location that is structured and easy to search. Weaker signal (network paths shown) A Screenshot of Kerbal Space Program. I can't see why they wouldn't be able to. kerbal space program - Calculate Satellite Constellation Launch 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. 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. Number of satellites - Three satellites are enough to form a complete ring around Kerbin. Use RA-100 relays. How to build a satellite network around Kerbin which guarantees full coverage? A minor scale definition: am I missing something? I have bi-coupler and tri-coupler versions also. The End. With 20 x 100GM satellites, you'd have a power of 945 GM and you'd be able to talk to a level 3 tracking station from 486 GM or to a probe with NO antenna and only the 5k onboard from about 68 MM - within the kerbin SOI, for example. How to achive a highly eccentric polar orbit around the sun oriented orthogonal to the ecliptic? Paste as plain text instead, This video tutorial demonstrates how to build, launch and set up a relay satellite network in KSP. 8 direct antennas therefore, will then double communication range for transmitting data. 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!]. What's the difference between relay and direct antennas? :: Kerbal Use RA-2 relays. Post-Burn Attitude Control. If you like, you can add a command to maintain attitude after the burn. 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. Mun/Minmus occlusion: All the satellites can get occluded when either. Making three trips per body seems like a complete waste of time and resources when these satellites weight so little. A steep launch requires fewer RemoteTech-specific skills but is less efficient (and may lead to a broken rocket while playing FAR), while the flight computer gives you the freedom to build and launch your rocket how you like but requires you to pick up more advanced skills right away. Double-check that you have enough panel and battery capacity to cover the energy needs of your antenna(s), since RemoteTech antennas use a lot more power than the stock versions. You can do the same on upper levels using cubic octagonal struts to create extra nodes). For the first, I settled on an orbital altitude of 7.5Gm. 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. It looks more or less stock to me, although on close inspection it has some fiddly bits I can't quite identify. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. Doesn't save mass, but it does allow for SLIGHTLY longer satellites. When a gnoll vampire assumes its hyena form, do its HP change? This means tuning your launch trajectory so that you finish your final burn less than 280 km (27 longitude) downrange of KSC. A second equatorial triangle orbit at around 300,000km. Setting the target now will give you one less thing to worry about in the hectic minute before orbital insertion. Hello- I thought in this play-through it would be fun to set up my own relay satellite network. Some trial and error may be necessary if youre used to shallower launches, but the traditional 45 ascent path should work. Check that the Delay (+ signal) display reads one minute. All rights reserved. The mission was to do a large number of science experiments in every Mun biome in one trip. Your previous content has been restored. For an inner orbit (pPost Your Satellite Designs - KSP1 The Spacecraft Exchange - Kerbal I've just started playing 1.2, loving it so far! use the relays propulsion to circularise the orbit and match the target orbital period. Relay satellites are exceptionally useful if put into a suitable type of Orbit according to the circumstance. New comments cannot be posted and votes cannot be cast. A relay satellite must have at least one relay-capable antenna and a probe core. Hence, by launching a second satellite at t, this one is not only t days behind the first, but also t2 forward. Period of Kerbin orbit k = 426 days You can get more details in this KSP forum post, which takes it from this research paper (paywall). Have you checked if the two antennas are in range to communicate with each other? Method 2: Flight Computer. Dont forget to reset the delay to 0 when youre done! Thats it! 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. I thought the gold bit was a probe core, but it's the wrong shape. You can post now and register later. (A spacecraft consisting of a pilot would not be affected.) Thanks, found the answer. These are landers, but it works just as well with satellites. Relay satellites and probe control :: Kerbal Space Program General This tutorial does not require any mods other than RemoteTech. As for any KSP probe, you will need a probe core, a battery, and (once you have the tech) solar panels. Note: Your post will require moderator approval before it will be visible. Method 1: Steep Ascent. And what on the Probe around the Mun? For ever-higher orbits, you will only be in range in an ever-narrower circle centered on Mission Control. Circle The period is the same as the target orbital period. Its just a matter of being careful. Blind spots: Having a ring of satellites leaves blind spots on the surface (poles in case of equatorial ring). 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. Send a couple small relay satellites with your probe. It only takes a minute to sign up. Your satellite may just not be powerful enough to be better than Kerbin ground stations. The relay sats don't need much v - just enough to put them in the orbit you want after you get to Eve. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Your second probe might have some visual mods, or maybe some custom dish parts because I don't see a stock dish that looks exactly like those dishes do Ditto your forward solar panels; they either look like custom textures for the 3x2 stock panel, or custom parts. Pasted as rich text. Use RA-2 relays. By: AlexMBrennan. Polar triangle orbit above 250km. Fortunately, getting into a stable orbit before you lose control doesnt demand any precision computing. Reddit and its partners use cookies and similar technologies to provide you with a better experience. 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. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. Will keep at it, now I've got a better understanding of CommNet! 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. 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. Missions to your homeworld's moons are required to use an HG-5 or equivalent, missions to the inner . This is a small cost to do and allows you to range much further than KSC can pull off. The heat shields are SSTU. 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. If you put the relays on opposite sides of a highly elliptical polar orbit, you should have very little loss of signal time. Its antenna is a Communotron 16. 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. The best answers are voted up and rise to the top, Not the answer you're looking for? Polar triangle orbit above 700km. Let's ignore occlusion by Mun and Minmus for now and focus only on what it takes to not get blocked by Kerbin. 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 try it for your first constellation : All rights reserved. Researching Electrics, which unlocks solar panels, is recommended but not required. With a 2G antenna on probe, this should give you complete coverage within planetary spheres of influence. Every time it passes over KSC, you can send or schedule more commands. rev2023.4.21.43403. I'm using two HG-5 High Gain Antennae (class 3) on my relay and the Communotron 15 (class 2) on my lander. Use RA-2 relays. By the end, you should understand: You must have researched Flight Control, which unlocks the Stayputnik probe core and the Reflectron DP-10 omnidirectional antenna. A set of six evenly space relays at around 4,000,000km. Multi-Satellite Launches - Kerbal Space Program Forums 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. Tutorial - Interplanetary Networks Rather than opening instantly, the solar panels will appear in the queue, scheduled to open after the delay. Deep space coverage may not be perfect. Will I need to set up a relay Network to do this? How do I view my network? KSP 1.2: How To Create a Geostationary Relay Network Helpful Linkshttps://wiki.kerbalspaceprogram.com/wiki/CommNethttp://forum.kerbalspaceprogram.com/index.php?/topic/149099-commnet-signal-strength-calculator-antenna-selector/https://ksp-visual-calculator.blaarkies.com/https://wiki.kerbalspaceprogram.com/wiki/Tutorial:Ideal_Orbits_for_Communication_Satelliteshttps://wiki.kerbalspaceprogram.com/wiki/Tutorial:Setting_up_a_CommNet_system00:00 Constructing the Relays02:46 Launching for our Destination04:04 Deploying the Relay Satellites This tutorial covers the basics of launching a standalone satellite in RemoteTech. Relay sat. The transmission would be 13 packets and consume 78 in 7.8 seconds. How much electricity does a relay satellite use? Equatorial triangle orbit above 138km. By accepting all cookies, you agree to our use of cookies to deliver and maintain our services and site, improve the quality of Reddit, personalize Reddit content and advertising, and measure the effectiveness of advertising. 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. Valve Corporation. Which gives t = p/(4(1 - p/k)) 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. Otherwise this scheme is resistant to placement errors. Of course the trouble in KSP doesn't have Lagrange points (which is what Queqiao orbits). Showing 1 - 13 of 13 comments (The "line up" will happen if, and only if, the phase angle differences between any one satellite, and any two other satellites adds up to somewhere near 180 degrees. 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). 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. But what about a larger orbit ? Could a subterranean river or aquifer generate enough continuous momentum to power a waterwheel for the purpose of producing electricity? What does "Smote their breasts" signify in Luke 23:48? Learn more about Stack Overflow the company, and our products. Kerbin, Mun and Minmus block one satellite each, or. To control a probe or satellite from the ground, you need a reliable communications link over which to send commands to mission control. Since electricity isn't consumed when a vehicle isn't controlled by the player, electric charge storage and generation isn't required. 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). Why did DOS-based Windows require HIMEM.SYS to boot? Equatorial triangle orbit above 13km. In a mature space program, a network of commsats will help you relay transmissions in any direction, but you dont have that luxury at the start of the game. One between Kerbin and Duna with six satellites. A second equatorial triangle orbit at around 60,000km. Was Aristarchus the first to propose heliocentrism? Placing the satellites in a roughly equatorial orbit leaves the blind spots at the poles (our main concern is that the KSC does not get into the blind spot). Effect of a "bad grade" in grad school applications. I basically do what @Geonovast posted. High-Powered Antennas. I've watched a couple of videos on how to set them up but I feel like the reason why you should set them up is quite often missing from these videos. Should have a short-range dish pointed at Kerbin, to connect to the low-orbit network, and one or more long-range dishes pointed at the destination planet (s). Add a relay satellite on the top ( RA-2, RA-15, or RA-100, depending on range) Done! If you have the Comms DTS-M1, right-click on it while on the launchpad, then click the button marked No Target. Privacy Policy. :D. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Archived post. I'm pretty sure three satellites on the same orbit would be enough, but I haven't had a chance to try 1.2 yet. 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. Polar triangle orbit. 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. > I like to use my polar relay as a synchronization timer in case my Draim constellation desynchronizatizes. Relay Satellites are used to communicate with the Kerbal Space Center without the need for a direct connection to it. 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? 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. In the window that opens, select Mission Control to make it the antennas target. Although I am checking in version 1.5, so they might have new skins in later versions. With the fact that each antenna has a limited range, this makes relay satellites a necessity for almost every interplanetary mission[citation needed]. You now have a basic satellite in orbit around Kerbin. At low tech levels you have access to only three antennas: the Communotron 16, the Reflectron DP-10, and the Comms DTS-M1. However many Life Support mods will allow power drain from inactive crafts. 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). Resonant Orbit Calculator (Kerbal Space Program) - meyerweb.com The other two antennas are optional for low enough orbits. is there such a thing as "right to be heard"? You probably. Use RA-100 relays. Launch however you usually do. If you have solar panels, deploy them as soon as you are out of the atmosphere, even if its a night launch. Anyway, worth mentioning is that this is a very inefficient way to do a relay satellite. An alternate strategy is to bind the antenna to an action group together with the satellites solar panels, and trigger the group to deploy everything once you leave the atmosphere. Of course if you want to place your satellites evenly on the same orbit as they already are, without fiddling with temporary elliptical orbits, then they'll just stay right where they are for eternity And since I did not test all of this and could have made a huge and humiliating mistake, please tell me if your tests prove me right ! 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). 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. Its ok if you do this while still in the atmosphere. With a 15G antenna, you get much better deep space coverage. What "benchmarks" means in "what are benchmarks for?". And so far, signal will always use the best path available. How to build a Satellite Network? - KSP1 Gameplay Questions and I see in the manual it says the distance for the stock antenna (in command modules and probe cores, class 0) is 5km, and 50km for class 1 and 158km for class 3. If you don't have the extra ground stations, then you can only talk to KSC, which is facing away from your ship 50% of the time. Unfortunately, a path like that means you wont reach orbit until you are out of sight of Mission Control, and therefore out of contact. 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? Or you can just leave it where it is, happily beeping away. 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. But I find it makes sense to put fewer sats on the top, so the fairing can taper around them. So, for four satellites, they should be spaced about 46 days apart. Left: A comlink-friendly ascent path. Is there a generic term for these trajectories? The final queue should look something like this picture (the Toggle SAS command is optional). 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. There is also an advanced difficulty setting where you don't have stations all over Kerbin but only have the KSC. So four 15G communication dishes on one sathave a range of 42 gm, which if I recall covers everything but Jool and Eeloo. Spacing - Generally, so long as any satellite can see the other two, everything will work, but placing them evenly will leave more room for error from orbital period mismatch to accumulate. What does 'They're at four. 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). Please consider starting a new thread rather than reviving this one. Yes, that's how combine works. Tutorial:Setting up a CommNet system - Kerbal Space Program 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. The orbital altitude must be greater than the radius of the body you are orbiting. I am trying to deploy three relay satellite constellations. The satellite is on the same side of the mun as the probe and has full signal from Kerbin. This is so much the right answer. You may omit the third ring but deep space coverage in the outer system may be a bit spotty. So there, the separation will be of p*t/k - t, but "forward". Arqade is a question and answer site for passionate videogamers on all platforms. Then, open the flight computer by clicking on the calculator icon below the mission clock, followed by to open the command queue. Adding EV Charger (100A) in secondary panel (100A) fed off main (200A), Generic Doubly-Linked-Lists C implementation. Squad might want to make that necessity a little more clear. 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.
