To clarify, I understand the irl counterpart to a relay Network I'm more wondering if they're actually useful/needed in the game. How to build a satellite network around Kerbin which guarantees full coverage? You can also slightly rotate the two bottom satellites so they are more "next to" each other than facing off. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. Polar triangle orbit above 700km. 8 direct antennas therefore, will then double communication range for transmitting data. Also one RA-2 can reach anywhere in kerbin's SOI that it has line of sight to, at least out to Minmus orbit. Was Aristarchus the first to propose heliocentrism? Nice, now we get to the problem: when the landing probe (it is carrying no antenna) gets occluded by the mun, after losing contact with Kerbin it doesn't connect to the satellite to relay its signal. 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. Use RA-2 relays. Back before they made a real atmosphere I frequently sent up 5 satellites at a time, 4 radially and 1 on the front. This means tuning your launch trajectory so that you finish your final burn less than 280 km (27 longitude) downrange of KSC. You can match that with 4 relays on one probe, or you can double it with 8. To control a probe or satellite from the ground, you need a reliable communications link over which to send commands to mission control. 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 : Now warp to your Ap and deploy the first relay. Number of satellites - Three satellites are enough to form a complete ring around Kerbin. But what about a larger orbit ? Parabolic, suborbital and ballistic trajectories all follow elliptic paths. Connect and share knowledge within a single location that is structured and easy to search. Why did DOS-based Windows require HIMEM.SYS to boot? At low tech levels you have access to only three antennas: the Communotron 16, the Reflectron DP-10, and the Comms DTS-M1. 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). Reddit and its partners use cookies and similar technologies to provide you with a better experience. KSP doesn't calculate a non-active crafts power usage or levels due to how the craft is handled by the game in the inactive state. 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. :D. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. If you have an antenna other than the DP-10, you will need to activate it in flight. Equatorial triangle orbit above 700km. Polar triangle orbit above 13km. Polar triangle orbit. A set of six evenly space relays at around 4,000,000km. Has depleted uranium been considered for radiation shielding in crewed spacecraft beyond LEO? 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. 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. 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. Could someone explain that as well? Polar triangle orbit above 200km. 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. I am trying to deploy three relay satellite constellations. For an inner orbit (p I like to use my polar relay as a synchronization timer in case my Draim constellation desynchronizatizes. 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). Effect of a "bad grade" in grad school applications. Use mod filters to select craft that; will work With selected mods. 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). 3 Satellites in an equal orbit forming an equalateral triangle with eachother. I somehow missed interstage nodes since they were added ages ago, and haven't seen them in any videos that I can remember. If not, is there a mod or config option to make folding antennas work as relays? What antenna are you using on the relay? Suppose you want to put three relay satellites into circular polar orbit around Minmus. All rights reserved. Using an Ohm Meter to test for bonding of a subpanel. Or you can just leave it where it is, happily beeping away. With the addition of CommNet, you need a system of relays to connect back to the KSC. Helpful Linkshttps://wiki.kerbalspaceprogram.com/wiki/Comm. 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. 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. Which gives t = p/(8(p/k - 1)). When a gnoll vampire assumes its hyena form, do its HP change? Squad might want to make that necessity a little more clear. All trademarks are property of their respective owners in the US and other countries. If you have an account, sign in now to post with your account. If you have the Comms DTS-M1, right-click on it while on the launchpad, then click the button marked No Target. There is also an advanced difficulty setting where you don't have stations all over Kerbin but only have the KSC. 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. The HG-5 is a folding relay antenna, it's just not very strong. 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. 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. If that's the case, then you have to replicate the extra ground stations in space with a ring of relays around Kerbin. So four 15G communication dishes on one sathave a range of 42 gm, which if I recall covers everything but Jool and Eeloo. 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. Hence, by launching a second satellite at t, this one is not only t days behind the first, but also t2 forward. For most practical applications an easy solution is to have a ring of three evenly spaced satellites in high (2500km-7000km) circular equatorial orbits. 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. Then open each panel by right-clicking or using an action group, as in normal KSP. This page was last edited on 24 March 2023, at 18:10. 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. One between Kerbin and Duna with six satellites. What are the advantages of running a power tool on 240 V vs 120 V? I want to send a probe to Eve as this is my first planetary mission and I'd rather not risk kerbals. A minor scale definition: am I missing something? Equatorial - This system has blind spots on the surface. How to build a satellite network around Kerbin which guarantees full coverage? Arqade is a question and answer site for passionate videogamers on all platforms. Researching Electrics, which unlocks solar panels, is recommended but not required. Launching a satellite into orbit means it will, sooner or later, end up on the far side of the planet. After t days have passed : Especially early on, the large relay will get sent as a science probe that can also act as a relay, then later in the career the smaller relay network will get set up. And for total coverage do triple relay sat launches for the Mun and Minmus.
