load your currently installed mods. Altitude depends on moon (500km for Laythe, 300km for Vall, 600km for Tylo, 65km for Bop and 44km for Pol). The contract is to send a satellite with an appropriate dish or combination of dishes into an orbit low enough that surface missions can use the whip antenna instead of having to pack a big dish (so long as a relay is overhead, of course). Let's ignore occlusion by Mun and Minmus for now and focus only on what it takes to not get blocked by Kerbin. If you use CKAN, drop your 'installed-default.ckan' file here to auto select mods explain this. Use RA-100 relays. Cookie Notice Once you get the really big satellite dishes, the signal will always bounce off that. These are landers, but it works just as well with satellites. Polar triangle orbit above 210km. Paste as plain text instead, I am trying to deploy three relay satellite constellations. Please consider starting a new thread rather than reviving this one. This satellite is out of control . use the relays propulsion to circularise the orbit and match the target orbital period. 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 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. Really like the design of your quad-probe. All trademarks are property of their respective owners in the US and other countries. 2. Polar triangle orbit above 320km. two satellites line up and both get occluded by Mun/Minmus, and the last one gets occluded by the other one. But what about a larger orbit ? Satellite exploding while in transfer orbit. For more information, please see our I want to send a probe to Eve as this is my first planetary mission and I'd rather not risk kerbals. 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. You can post now and register later. At low tech levels you have access to only three antennas: the Communotron 16, the Reflectron DP-10, and the Comms DTS-M1. Interpreting non-statistically significant results: Do we have "no evidence" or "insufficient evidence" to reject the null? If you want probes at the poles, one solution is to just have another ring in a polar orbit. 8 direct antennas therefore, will then double communication range for transmitting data. Otherwise this scheme is resistant to placement errors. Hence, by launching a second satellite at t, this one is not only t days behind the first, but also t2 forward. It only takes a minute to sign up. To clarify, I understand the irl counterpart to a relay Network I'm more wondering if they're actually useful/needed in the game. Any other Suggestions you may have! 2 Satelites in matching orbits in opposite ends of eachother. 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. Check that the Delay (+ signal) display shows no delay. Privacy Policy. Its antenna is an HG-5. SpanishInquisitor27 4 yr. ago Now warp to your Ap and deploy the first relay. 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. 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. If the satellites are high up the spots will be really small, but any terrain irregularities close to them will easily block the signal. Also, it's interesting to see that in the case of p = k, the calculations divides by 0 ! The mission was to do a large number of science experiments in every Mun biome in one trip. Why do men's bikes have high bars where you can hit your testicles while women's bikes have the bar much lower? a normal antenna can connect to a relay antenna or the KSC directly. New comments cannot be posted and votes cannot be cast. About 3000g orbiting outside Minmus. Thank you. Thanks, found the answer. Helpful Linkshttps://wiki.kerbalspaceprogram.com/wiki/Comm. One between Dres and Jool with eight satellites. That would probably be close enough. Kerbal Space Program 1 KSP1 The Spacecraft Exchange Post Your Satellite Designs Post Your Satellite Designs By Wcmille, December 28, 2016 in KSP1 The Spacecraft Exchange Share Followers 1 Reply to this topic Start new topic 1 2 Next Page 1 of 2 Wcmille Members 116 312 About me: Rocketman Posted December 28, 2016 However, I was wondering, in what circumstances does your vessel bounce its signal off a relay satellite? Use RA-100 relays. Period of target orbit p = 184 days Some trial and error may be necessary if youre used to shallower launches, but the traditional 45 ascent path should work. Showing 1 - 13 of 13 comments Post-Burn Attitude Control. Polar triangle orbit. Making three trips per body seems like a complete waste of time and resources when these satellites weight so little. I thought the gold bit was a probe core, but it's the wrong shape. Circular orbit - Just easier to work with (and to do the math). Privacy Policy. Use RA-15 relays.

Otherwise you risk launching nothing but a future fireworks display for the citizens on the far side of Kerbin. Doesn't save mass, but it does allow for SLIGHTLY longer satellites. To establish this link, you require an antenna that has the range to reach it and no obstructions between them. Using an Ohm Meter to test for bonding of a subpanel. Equatorial - This system has blind spots on the surface. Missions to your homeworld's moons are required to use an HG-5 or equivalent, missions to the inner . So there, the separation will be of p*t/k - t, but "forward". 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. This tutorial covers the basics of launching a standalone satellite in RemoteTech. Archived post. 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.. 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. Circle The period is the same as the target orbital period. You now have a basic satellite in orbit around Kerbin. Polar triangle orbit above 60km. There is also an advanced difficulty setting where you don't have stations all over Kerbin but only have the KSC. Which gives t = p/(8(p/k - 1)). Use RA-2 relays. 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. A high orbit is easier to work with. 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. Can't remember if those or stock or not. A set of six evenly space relays at around 4,000,000km. 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). Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. Adding additional relay rings around Kerbol should also help with coverage. The best answers are voted up and rise to the top, Not the answer you're looking for? The satellite is on the same side of the mun as the probe and has full signal from Kerbin. 3 Satellites in an equal orbit forming an equalateral triangle with eachother. Since Kerbin is faster than, say, Jool, the second satellite you launch will end up forward the first anyway. There are two ways to avoid this, depending on your play style: following a steep launch path or using the flight computer. But adding it 40 degrees away is OK and will prevent occlusion from Mun/Minmus.). Equatorial triangle orbit above 210km. This means tuning your launch trajectory so that you finish your final burn less than 280 km (27 longitude) downrange of KSC. On the other end, if you go over 8970km, you will get into the Mun's sphere of influence, and your satellite will get thrown off trajectory when an encounter happens. Why has my Command Module's orbit not decayed? Relay satellites are exceptionally useful if put into a suitable type of Orbit according to the circumstance. 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. This tutorial does not require any mods other than RemoteTech. A triangle orbit will be the main orbit used in the constellations. This page was last edited on 19 July 2020, at 20:55. Espaol - Latinoamrica (Spanish - Latin America), https://en.wikipedia.org/wiki/Tundra_orbit. Is there a weapon that has the heavy property and the finesse property (or could this be obtained)? 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). The other two antennas are optional for low enough orbits. (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. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. 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. Left: A comlink-friendly ascent path. (I recommend the decoupler be set to 0 force so your orbits don't change when you detach.) what's wrong here? If an antenna can connect to the KSC (e.g. Any clues? In order to have remote control of a vessel, it must have a communications link with Kerbal Space Center. 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. The HG-5 is a folding relay antenna, it's just not very strong. You cannot paste images directly. Use RA-2 relays. rev2023.4.21.43403. 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. With the fact that each antenna has a limited range, this makes relay satellites a necessity for almost every interplanetary mission[citation needed]. Or you can just leave it where it is, happily beeping away. 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. Rocket scientist alternative: if you are more of a rocket scientist than me, you can place four satellites in a tetrahedral formation around Kerbin. So how do you launch and control the very satellites that are supposed to help you do the controlling? It looks more or less stock to me, although on close inspection it has some fiddly bits I can't quite identify. Have you checked if the two antennas are in range to communicate with each other? Method 2: Flight Computer. If that's the case, then you have to replicate the extra ground stations in space with a ring of relays around Kerbin. What "benchmarks" means in "what are benchmarks for?". Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. This satellite is in visual range of KSC. Cookie Notice 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 : Learn more about Stack Overflow the company, and our products. Rather than opening instantly, the solar panels will appear in the queue, scheduled to open after the delay. Could someone explain that as well? Clear editor. (A spacecraft consisting of a pilot would not be affected.) Equatorial triangle orbit above 700km. 184 / (4*0.568) = 81 days. For the first, I settled on an orbital altitude of 7.5Gm. Use RA-2 relays. Three panels is enough for near Kerbin, but you'll need more if you go farther out. An elliptical orbit might be better if you want to do it with one sat, but then you'd have to adjust orbit every once in a while to have the AP above your base/probe/rover. Setting the target now will give you one less thing to worry about in the hectic minute before orbital insertion. Such a formation will provide coverage on all of Kerbin's surface and cannot get fully occluded by Mun/Minmus. 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. This tutorial covers the basics of launching a standalone satellite in RemoteTech. By: AlexMBrennan. A relay satellite must have at least one relay-capable antenna and a probe core. If you have solar panels, you need to make sure they get deployed once out of the atmosphere, or your satellite may run out of power before its next pass over KSC. For a start, I have placed a relay satellite in KEO. 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. Use RA-2 relays. Launch. Use RA-2 relays. One between the orbit of Moho and Eve with four satellites. You build relays satellites at the target not the source, they don't do anything orbiting kerbin. and our Right: The position of a satellite in an 80km orbit just before it loses line of sight with KSC. 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. Connect and share knowledge within a single location that is structured and easy to search. What are the advantages of running a power tool on 240 V vs 120 V? Effect of a "bad grade" in grad school applications. Is there a generic term for these trajectories? 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. I have bi-coupler and tri-coupler versions also. Which is a pain so avoid this if at all possible. As for any KSP probe, you will need a probe core, a battery, and (once you have the tech) solar panels. What does "Smote their breasts" signify in Luke 23:48? Has depleted uranium been considered for radiation shielding in crewed spacecraft beyond LEO? Equatorial triangle orbit above 600km. How can I control PNP and NPN transistors together from one pin? For more information, please see our Valve Corporation. This is a small cost to do and allows you to range much further than KSC can pull off.
