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 the addition of CommNet, you need a system of relays to connect back to the KSC. Type a delay that corresponds to just after the orbit insertion is finished (any attitude commands sent during the burn will be ignored). I looked for the screenshots, no luck. How to achive a highly eccentric polar orbit around the sun oriented orthogonal to the ecliptic? The other two antennas are optional for low enough orbits. Well actually kinf of yes. 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. If not, is there a mod or config option to make folding antennas work as relays? Its antenna is a Communotron 16. 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.. Circle The period is the same as the target orbital period. With a 2G antenna on probe, this should give you complete coverage within planetary spheres of influence. Note: Your post will require moderator approval before it will be visible. This satellite is out of control . English version of Russian proverb "The hedgehogs got pricked, cried, but continued to eat the cactus". 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). Making three trips per body seems like a complete waste of time and resources when these satellites weight so little. So how do you launch and control the very satellites that are supposed to help you do the controlling? With the fact that each antenna has a limited range, this makes relay satellites a necessity for almost every interplanetary mission[citation needed]. 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. However, I have this other satellite which is out of contact with KSC, but in visual range of the relay satellite. It assumes you have not yet established a comsat network, so that the only connection of interest is a direct link between the . 2023 Take-Two Interactive Software, Inc. Reddit and its partners use cookies and similar technologies to provide you with a better experience. Relay sat. 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. The mission was to do a large number of science experiments in every Mun biome in one trip. New comments cannot be posted and votes cannot be cast. Of these three, the Reflectron DP-10 is the only one that can work in Kerbins lower atmosphere without breaking off, so you must include it on the satellite (several atmosphere-safe dishes become available later in the tech tree). 2. Cookie Notice 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. You build relays satellites at the target not the source, they don't do anything orbiting kerbin. This is useful for setting up things like CommNet constellations. This video tutorial demonstrates how to build, launch and set up a relay satellite network in KSP. Equatorial triangle orbit above 130km. 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. 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. 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. Use RA-2 relays. Really like the design of your quad-probe. I am trying to deploy three relay satellite constellations. Adding additional relay rings around Kerbol should also help with coverage. Relay Satellites are used to communicate with the Kerbal Space Center without the need for a direct connection to it. 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. Relay refers to the relay type antennae. 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. 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). Let's say p is the period of your target orbit and k the period of Kerbin orbit. Polar triangle orbit above 250km. It looks more or less stock to me, although on close inspection it has some fiddly bits I can't quite identify. Some trial and error may be necessary if youre used to shallower launches, but the traditional 45 ascent path should work. Also one RA-2 can reach anywhere in kerbin's SOI that it has line of sight to, at least out to Minmus orbit. Factor of division = 1 - 184 / 426 = 0.568 Its antenna is an HG-5. Use RA-2 relays. 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. what's wrong here? Its ok if you do this while still in the atmosphere. What differentiates living as mere roommates from living in a marriage-like relationship? Thank you. 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. You probably. Use RA-2 relays. 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 : 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. Equatorial triangle orbit above 320km. Parabolic, suborbital and ballistic trajectories all follow elliptic paths. 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. Anyway, worth mentioning is that this is a very inefficient way to do a relay satellite. Archived post. So four 15G communication dishes on one sathave a range of 42 gm, which if I recall covers everything but Jool and Eeloo. Any other Suggestions you may have! I would like the satellites in each constellation to be equally spaced. 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. Otherwise you risk launching nothing but a future fireworks display for the citizens on the far side of Kerbin. The orbital altitude must be greater than the radius of the body you are orbiting. Blind spots: Having a ring of satellites leaves blind spots on the surface (poles in case of equatorial ring). They are 100G, but noted, thanks. To play this tutorial, you should already know how to launch non-RemoteTech rockets, including basic rocket design, staging, and using maneuver nodes. Setting the target now will give you one less thing to worry about in the hectic minute before orbital insertion. 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. > With proper resonance, you are in a mapping orbit and can complete grab/temp scans above x contacts without fuel burn. 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. Now warp to your Ap and deploy the first relay. Arqade is a question and answer site for passionate videogamers on all platforms. 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? 2 identical dishes have a power of 1.68 times a single dish, and 4 dishes have a power of 2.8 times a single dish. rev2023.4.21.43403. Why don't we use the 7805 for car phone chargers? All rights reserved. Post-Burn Attitude Control. 184 / (4*0.568) = 81 days. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Why do men's bikes have high bars where you can hit your testicles while women's bikes have the bar much lower? 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. Your satellite may just not be powerful enough to be better than Kerbin ground stations. Is there a generic term for these trajectories? That way, you wont have to worry about running out of power while halfway around Kerbin. And so far, signal will always use the best path available. Use RA-100 relays. Optional Steps. Yes, that's how combine works. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Not to mention transmitting grav scans for every biome! You may omit the third ring but deep space coverage in the outer system may be a bit spotty. Period of Kerbin orbit k = 426 days Unexpected uint64 behaviour 0xFFFF'FFFF'FFFF'FFFF - 1 = 0? Do not activate the antenna yet, or it will break off as your rocket builds up speed. Mun/Minmus occlusion: All the satellites can get occluded when either. two satellites line up and both get occluded by Mun/Minmus, and the last one gets occluded by the other one. All rights reserved. Polar orbit above 6,000km. ], Maintaining control during probe atmospheric landing with RemoteTech. Also, it's interesting to see that in the case of p = k, the calculations divides by 0 ! One between Kerbin and Duna with six satellites. they have have antenna extended and are in range but their not bouncing back signals to get full conection. As for any KSP probe, you will need a probe core, a battery, and (once you have the tech) solar panels. 8 direct antennas therefore, will then double communication range for transmitting data. Here's how to set up a constellation of satellites to ensure complete coverage. 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. I have too many KSP screenshots. And what on the Probe around the Mun? A triangle orbit will be the main orbit used in the constellations. Scan this QR code to download the app now. 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. With a 15G antenna, you get much better deep space coverage. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. Connect and share knowledge within a single location that is structured and easy to search. For the first, I settled on an orbital altitude of 7.5Gm. Your launch trajectory is important. If you have an account, sign in now to post with your account. and our > I like to use my polar relay as a synchronization timer in case my Draim constellation desynchronizatizes. If you put the relays on opposite sides of a highly elliptical polar orbit, you should have very little loss of signal time. The transmission would be 13 packets and consume 78 in 7.8 seconds. 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. Circular orbit - Just easier to work with (and to do the math). This satellite is in visual range of KSC. www.Twitter.com/Matt_LowneThe background music is the gallery theme from Sonic Generations, and the outro music is the rooftop run theme from the same game.C. Another thing to consider is polar relays are great for many things: > Anomaly detection over several days (at sufficiently high altitude you can see the entire planet face in Kerb net). All trademarks are property of their respective owners in the US and other countries. 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. Pasted as rich text. These are landers, but it works just as well with satellites. Dedicated to the growth and advancement of amateur rocket scientists! On what basis are pardoning decisions made by presidents or governors when exercising their pardoning power? 1 Answer Sorted by: 10 For most practical applications an easy solution is to have a ring of three evenly spaced satellites in high (2500km-7000km) circular equatorial orbits. A relay satellite must have at least one relay-capable antenna and a probe core. Polar triangle orbit above 138km. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Squad might want to make that necessity a little more clear. Display as a link instead, I think I have a pic around here somewhere I'll try to dig it up and update this post with it. So the actual separation, in time, is actually t - t2 = t - t*p/k = t*(1 - p/k). Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. 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. 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. Using an Ohm Meter to test for bonding of a subpanel. 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. You can post now and register later. I want to send a probe to Eve as this is my first planetary mission and I'd rather not risk kerbals. It brought me ~30-40 days separation. In fact I thought it was one of my pics One trick, mount the two interior satellites facing each other and you save the need for that inner truss, as the middle satellite will be attached to the same truss the top satellite is on, only on the bottom of it. Launching a satellite into orbit means it will, sooner or later, end up on the far side of the planet. Use RA-2 relays. The best answers are voted up and rise to the top, Not the answer you're looking for? Polar triangle orbit above 700km. And for total coverage do triple relay sat launches for the Mun and Minmus. Polar triangle orbit above 60km. Didn't know about having to enable the option. 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. 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. Adding EV Charger (100A) in secondary panel (100A) fed off main (200A). The large solar panels sort of look like Gigantor arrays maybe on pipes or actuators? Solves a lot of problems. The pod is a little tiny 1-kerbal unit that is perfect for small landers from one of the Umbra Space Industries mods. Has depleted uranium been considered for radiation shielding in crewed spacecraft beyond LEO? 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. 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. How to build a satellite network around Kerbin which guarantees full coverage? 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. Relay Satellites are used to communicate with the Kerbal Space Center without the need for a direct connection to it. I tried launching one satellite every 46 days, but that didn't work. Use RA-2 relays. However, I was wondering, in what circumstances does your vessel bounce its signal off a relay satellite? Relay satellites are exceptionally useful if put into a suitable type of Orbit according to the circumstance. In order to have remote control of a vessel, it must have a communications link with Kerbal Space Center. To clarify, I understand the irl counterpart to a relay Network I'm more wondering if they're actually useful/needed in the game. ', referring to the nuclear power plant in Ignalina, mean? The gold parts are Procedural Parts batteries. 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. In the window that opens, select Mission Control to make it the antennas target. Could a subterranean river or aquifer generate enough continuous momentum to power a waterwheel for the purpose of producing electricity? The relay sats don't need much v - just enough to put them in the orbit you want after you get to Eve. You cannot paste images directly. Does the 500-table limit still apply to the latest version of Cassandra? Why are players required to record the moves in World Championship Classical games? Once you get the really big satellite dishes, the signal will always bounce off that. This page was last edited on 19 July 2020, at 20:55. 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. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. If an antenna can connect to the KSC (e.g. Altitude depends on moon (500km for Laythe, 300km for Vall, 600km for Tylo, 65km for Bop and 44km for Pol). Suppose you want to put three relay satellites into circular polar orbit around Minmus. A minor scale definition: am I missing something? You can match that with 4 relays on one probe, or you can double it with 8. Polar triangle orbit above 320km. This page was last edited on 24 March 2023, at 18:10. A set of twelve evenly spaced relays at around 25,000,000km. I somehow missed interstage nodes since they were added ages ago, and haven't seen them in any videos that I can remember. Ok cool, thanks for the help guys! It only takes a minute to sign up. :D. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Use RA-2 relays. 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). However many Life Support mods will allow power drain from inactive crafts.
