Altitude depends on moon (500km for Laythe, 300km for Vall, 600km for Tylo, 65km for Bop and 44km for Pol). a normal antenna can connect to a relay antenna or the KSC directly. What are the advantages of running a power tool on 240 V vs 120 V? That gives an orbital period of roughly 184 days. how to plan pre-network missions around your limited line of sight to KSC. Equatorial triangle orbit above 13km. As for any KSP probe, you will need a probe core, a battery, and (once you have the tech) solar panels. If the satellites are high up the spots will be really small, but any terrain irregularities close to them will easily block the signal. Not to mention transmitting grav scans for every biome! All rights reserved. The satellite is on the same side of the mun as the probe and has full signal from Kerbin. Your link has been automatically embedded. 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.. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. I thought the gold bit was a probe core, but it's the wrong shape. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. I tried launching one satellite every 46 days, but that didn't work. 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. Will keep at it, now I've got a better understanding of CommNet! Really like the design of your quad-probe. 8 direct antennas therefore, will then double communication range for transmitting data. Equatorial triangle orbit above 320km. Pasted as rich text.

A second equatorial triangle orbit at around 60,000km. This page was last edited on 24 March 2023, at 18:10. Why do men's bikes have high bars where you can hit your testicles while women's bikes have the bar much lower? 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. The relay sats don't need much v - just enough to put them in the orbit you want after you get to Eve. Orbital height - In theory, you could go as low as double (Kerbin radius + atmospheric height), or 740km altitude, but the placement would have to be perfectly at 120 degrees phase angle. These are landers, but it works just as well with satellites. 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. But what about a larger orbit ? You can match that with 4 relays on one probe, or you can double it with 8. Could someone explain that as well? Any other Suggestions you may have! 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. 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. use the relays propulsion to circularise the orbit and match the target orbital period. Period of Kerbin orbit k = 426 days 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. For missions to high orbits (or just for practice before you send up a full-fledged comsat), you may wish to include one of the other antennas in your design. However, I was wondering, in what circumstances does your vessel bounce its signal off a relay satellite? Rather than opening instantly, the solar panels will appear in the queue, scheduled to open after the delay. Researching Electrics, which unlocks solar panels, is recommended but not required. So how do you launch and control the very satellites that are supposed to help you do the controlling? Relay Satellites are used to communicate with the Kerbal Space Center without the need for a direct connection to it. So there, the separation will be of p*t/k - t, but "forward". Circle The period is the same as the target orbital period. Suppose you want to put three relay satellites into circular polar orbit around Minmus. This tutorial covers the basics of launching a standalone satellite in RemoteTech. Equatorial triangle orbit above 130km. Note: Your post will require moderator approval before it will be visible. 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. Since Kerbin is faster than, say, Jool, the second satellite you launch will end up forward the first anyway. Helpful Linkshttps://wiki.kerbalspaceprogram.com/wiki/CommNethttp://forum.kerbalspaceprogram.com/index.php?/topic/149099-commnet-signal-strength-calculator-antenna-selector/https://ksp-visual-calculator.blaarkies.com/https://wiki.kerbalspaceprogram.com/wiki/Tutorial:Ideal_Orbits_for_Communication_Satelliteshttps://wiki.kerbalspaceprogram.com/wiki/Tutorial:Setting_up_a_CommNet_system00:00 Constructing the Relays02:46 Launching for our Destination04:04 Deploying the Relay Satellites 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). And what on the Probe around the Mun? Arqade is a question and answer site for passionate videogamers on all platforms. they have have antenna extended and are in range but their not bouncing back signals to get full conection. However, I have this other satellite which is out of contact with KSC, but in visual range of the relay satellite. SpanishInquisitor27 4 yr. ago 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). 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. Adding EV Charger (100A) in secondary panel (100A) fed off main (200A). How do I view my network? 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. That factor goes negative, so you should launch back in time ? You cannot paste images directly. What does "Smote their breasts" signify in Luke 23:48? So you see that you should further increase the delay between each launch to 81 days. rev2023.4.21.43403. Of course the trouble in KSP doesn't have Lagrange points (which is what Queqiao . Spacing - Generally, so long as any satellite can see the other two, everything will work, but placing them evenly will leave more room for error from orbital period mismatch to accumulate. By the end, you should understand: You must have researched Flight Control, which unlocks the Stayputnik probe core and the Reflectron DP-10 omnidirectional antenna. I was sort of inspired to do this by how the Chinese Chang'e 4 lander uses the Queqiao relay satellite to communicate with Earth from the far side of the Moon. The pod is a little tiny 1-kerbal unit that is perfect for small landers from one of the Umbra Space Industries mods. Privacy Policy. You probably. How to build a satellite network around Kerbin which guarantees full coverage? To play this tutorial, you should already know how to launch non-RemoteTech rockets, including basic rocket design, staging, and using maneuver nodes. Here's how to set up a constellation of satellites to ensure complete coverage. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. I don't have the buttons to the right of the clock that are in the OP's screenshot. Why did DOS-based Windows require HIMEM.SYS to boot? Why are players required to record the moves in World Championship Classical games? Use RA-15 relays. Dont forget to reset the delay to 0 when youre done! One long-range relay satellite in a very eccentric near-polar orbit (~80 km periapsis, ~80,000 km apoapsis, inclination near poles). If you put the relays on opposite sides of a highly elliptical polar orbit, you should have very little loss of signal time. Fortunately, getting into a stable orbit before you lose control doesnt demand any precision computing. and our Have you checked if the two antennas are in range to communicate with each other? Once you get the really big satellite dishes, the signal will always bounce off that. Transmission When the transmit button is pressed while reviewing experiment results, an antenna will automatically deploy to perform a transmission and then retract after completion. Scan this QR code to download the app now. When a gnoll vampire assumes its hyena form, do its HP change? There are two ways to avoid this, depending on your play style: following a steep launch path or using the flight computer. What "benchmarks" means in "what are benchmarks for?". I am trying to deploy three relay satellite constellations. Polar triangle orbit above 250km. Your satellite may just not be powerful enough to be better than Kerbin ground stations. load your currently installed mods. Please note that this page is incomplete, and requires the help of the community. Equatorial - This system has blind spots on the surface. Reddit and its partners use cookies and similar technologies to provide you with a better experience. Which ability is most related to insanity: Wisdom, Charisma, Constitution, or Intelligence? 3 Satellites in an equal orbit forming an equalateral triangle with eachother. 2 Satelites in matching orbits in opposite ends of eachother. Method 2: Flight Computer. Connect and share knowledge within a single location that is structured and easy to search. 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. 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. Then, open the flight computer by clicking on the calculator icon below the mission clock, followed by to open the command queue. You now have a basic satellite in orbit around Kerbin. A set of twelve evenly spaced relays at around 25,000,000km. is there such a thing as "right to be heard"? 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. Polar triangle orbit above 600km. Polar triangle orbit above 210km. Setting the target now will give you one less thing to worry about in the hectic minute before orbital insertion. Helpful Linkshttps://wiki.kerbalspaceprogram.com/wiki/Comm. Its just a matter of being careful. There is also an advanced difficulty setting where you don't have stations all over Kerbin but only have the KSC. https://wiki.kerbalspaceprogram.com/index.php?title=Relay_Satellite&oldid=104907. Period of target orbit p = 184 days Thats it! 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. Thanks for that. 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 can do this either by right-clicking on the antenna and clicking activate, or by binding it to an action group in the VAB. Missions to your homeworld's moons are required to use an HG-5 or equivalent, missions to the inner . You can get more details in this KSP forum post, which takes it from this research paper (paywall). Showing 1 - 13 of 13 comments Use RA-2 relays. Use RA-2 relays. Post-Burn Attitude Control. Polar triangle orbit. Paste as plain text instead, I somehow missed interstage nodes since they were added ages ago, and haven't seen them in any videos that I can remember. New comments cannot be posted and votes cannot be cast. The final queue should look something like this picture (the Toggle SAS command is optional). This satellite is out of control . Equatorial triangle orbit above 210km. Factor of division = 1 - 184 / 426 = 0.568 It's not them. Hence, by launching a second satellite at t, this one is not only t days behind the first, but also t2 forward. Effect of a "bad grade" in grad school applications. Archived post. Squad might want to make that necessity a little more clear. Dedicated to the growth and advancement of amateur rocket scientists! How can I control PNP and NPN transistors together from one pin? 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. Deep space coverage may not be perfect. After t days have passed : Making three trips per body seems like a complete waste of time and resources when these satellites weight so little. > With proper resonance, you are in a mapping orbit and can complete grab/temp scans above x contacts without fuel burn. 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. Relay satellites are exceptionally useful if put into a suitable type of Orbit according to the circumstance. We consider a smaller target orbit, so p
