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. Relays Not Working :: Kerbal Space Program General Discussions 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. kerbal space program - How to build a satellite network around Kerbin 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. Tutorial - First Satellite - GitHub Pages I am trying to deploy three relay satellite constellations. For an inner orbit (pRelay Satellite - Kerbal Space Program Wiki Blind spots: Having a ring of satellites leaves blind spots on the surface (poles in case of equatorial ring). Otherwise you risk launching nothing but a future fireworks display for the citizens on the far side of Kerbin. Upload or insert images from URL. Rather than opening instantly, the solar panels will appear in the queue, scheduled to open after the delay. These are landers, but it works just as well with satellites. Polar triangle orbit above 60km. Privacy Policy. Relay satellites and probe control :: Kerbal Space Program General Since electricity isn't consumed when a vehicle isn't controlled by the player, electric charge storage and generation isn't required. I like to stack multiple satellites per level, as shown below (those are smaller sats of course, but the same concept applies). 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. It looks more or less stock to me, although on close inspection it has some fiddly bits I can't quite identify. Also, it's interesting to see that in the case of p = k, the calculations divides by 0 ! But I find it makes sense to put fewer sats on the top, so the fairing can taper around them. I figure I could add 20 days to the launch window (launch every 66 days). For a start, I have placed a relay satellite in KEO. 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. Doesn't save mass, but it does allow for SLIGHTLY longer satellites. Relay Satellites are used to communicate with the Kerbal Space Center without the need for a direct connection to it. Minmus Relay Satellites : r/KerbalAcademy - Reddit So, for four satellites, they should be spaced about 46 days apart. Hello- I thought in this play-through it would be fun to set up my own relay satellite network. You cannot paste images directly. Sort by votes Sort by date use the relays propulsion to circularise the orbit and match the target orbital period. 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. 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. Resonant Orbit Calculator (Kerbal Space Program) - meyerweb.com Learn more about Stack Overflow the company, and our products. We consider a smaller target orbit, so pTutorial - Interplanetary Networks Right: The position of a satellite in an 80km orbit just before it loses line of sight with KSC. 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. KSC only boasts 250G. 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). 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. Execute the burn as accurately as possible. The gold parts are Procedural Parts batteries. This tutorial does not require any mods other than RemoteTech. 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. With a 15G antenna, you get much better deep space coverage. and our Could a subterranean river or aquifer generate enough continuous momentum to power a waterwheel for the purpose of producing electricity? This tutorial covers the basics of launching a standalone satellite in RemoteTech. Here's how to set up a constellation of satellites to ensure complete coverage. > 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. Post Your Satellite Designs - KSP1 The Spacecraft Exchange - Kerbal 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.
