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 ! Which is a pain so avoid this if at all possible. Squad might want to make that necessity a little more clear. Valve Corporation. 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. 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 plan pre-network missions around your limited line of sight to KSC. Post-Burn Attitude Control. Which ability is most related to insanity: Wisdom, Charisma, Constitution, or Intelligence? 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. a normal antenna can connect to a relay antenna or the KSC directly. 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. 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. New comments cannot be posted and votes cannot be cast. I think I have a pic around here somewhere I'll try to dig it up and update this post with it. Of course the trouble in KSP doesn't have Lagrange points (which is what Queqiao . 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. Use RA-2 relays. https://wiki.kerbalspaceprogram.com/index.php?title=Relay_Satellite&oldid=104907. What differentiates living as mere roommates from living in a marriage-like relationship? The best answers are voted up and rise to the top, Not the answer you're looking for? Launch however you usually do. The satellite is on the same side of the mun as the probe and has full signal from Kerbin. That way, you wont have to worry about running out of power while halfway around Kerbin. This video tutorial demonstrates how to build, launch and set up a relay satellite network in KSP. Connect and share knowledge within a single location that is structured and easy to search. 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. It only takes a minute to sign up. This tutorial covers the basics of launching a standalone satellite in RemoteTech. Could a subterranean river or aquifer generate enough continuous momentum to power a waterwheel for the purpose of producing electricity? 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. Does the 500-table limit still apply to the latest version of Cassandra? Is it safe to publish research papers in cooperation with Russian academics? How to build a satellite network around Kerbin which guarantees full coverage? If you have an antenna other than the DP-10, you will need to activate it in flight. If you have solar panels, deploy them as soon as you are out of the atmosphere, even if its a night launch. 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. Didn't know about having to enable the option. Use RA-2 relays. But what about a larger 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, Let's try it for your first constellation : Powered by Invision Community. We consider a smaller target orbit, so p Anomaly detection over several days (at sufficiently high altitude you can see the entire planet face in Kerb net). 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. Circle The period is the same as the target orbital period. Polar triangle orbit above 320km. 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.. However, I have this other satellite which is out of contact with KSC, but in visual range of the relay satellite. Yes, that's how combine works. To control a probe or satellite from the ground, you need a reliable communications link over which to send commands to mission control. 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. I've just started playing 1.2, loving it so far! I basically do what @Geonovast posted. Equatorial triangle orbit above 6,000km.

By: AlexMBrennan. Suppose you want to put three relay satellites into circular polar orbit around Minmus. 1% signal strength), then it will not switch to using a relay (even if it could boost signal to 99%) until something blocks the direct signal path and forces the sat to switch. Since Kerbin is faster than, say, Jool, the second satellite you launch will end up forward the first anyway. Learn more about Stack Overflow the company, and our products. Thanks, found the answer. Equatorial triangle orbit above 700km. Polar triangle orbit above 60km. Some trial and error may be necessary if youre used to shallower launches, but the traditional 45 ascent path should work. Use RA-100 relays. In the window that opens, select Mission Control to make it the antennas target. 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. 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. 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. Which gives t = p/(8(p/k - 1)). 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. The heat shields are SSTU. 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. Why do men's bikes have high bars where you can hit your testicles while women's bikes have the bar much lower? Use RA-2 relays. How to build a satellite network around Kerbin which guarantees full coverage? 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. 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). 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. Privacy Policy. Paste as plain text instead, and our 2 Satelites in matching orbits in opposite ends of eachother. Learn more about Stack Overflow the company, and our products. Is there a weapon that has the heavy property and the finesse property (or could this be obtained)? How to achive a highly eccentric polar orbit around the sun oriented orthogonal to the ecliptic? If you like, you can add a command to maintain attitude after the burn. 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. Every time it passes over KSC, you can send or schedule more commands. I can't see why they wouldn't be able to. If an antenna can connect to the KSC (e.g. Why did DOS-based Windows require HIMEM.SYS to boot? If you have another antenna, you can move the DP-10 from the satellite to the launchers upper stage, so you can discard it once its served its purpose. I got the same answer from the KSP fora, but with minimal explanation of the underlying math.
