(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. Didn't know about having to enable the option. 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 : 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. I am trying to deploy three relay satellite constellations. But what about a larger orbit ? So four 15G communication dishes on one sathave a range of 42 gm, which if I recall covers everything but Jool and Eeloo. 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. After t days have passed : A set of six evenly space relays at around 4,000,000km. 2023 Take-Two Interactive Software, Inc. The final queue should look something like this picture (the Toggle SAS command is optional). 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. The DP-10s main disadvantage is its 500 km range. Why do men's bikes have high bars where you can hit your testicles while women's bikes have the bar much lower? 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. Every time it passes over KSC, you can send or schedule more commands. One between Dres and Jool with eight satellites. Cookie Notice Was Aristarchus the first to propose heliocentrism? That gives an orbital period of roughly 184 days. You can post now and register later. 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. It looks more or less stock to me, although on close inspection it has some fiddly bits I can't quite identify. Hello- I thought in this play-through it would be fun to set up my own relay satellite network. If you have an antenna other than the DP-10, you will need to activate it in flight. What are the advantages of running a power tool on 240 V vs 120 V? A triangle orbit will be the main orbit used in the constellations. Satellite exploding while in transfer orbit. Use RA-15 relays. Once you are coasting to apoapsis, set a maneuver node to represent the final burn to reach orbit. Use RA-2 relays. How to build a satellite network around Kerbin which guarantees full coverage? 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. they have have antenna extended and are in range but their not bouncing back signals to get full conection. Thank you. Method 2: Flight Computer. Any other Suggestions you may have! This satellite is out of control . 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 ! On what basis are pardoning decisions made by presidents or governors when exercising their pardoning power? I've just started playing 1.2, loving it so far! KSC only boasts 250G. 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. Privacy Policy. And so far, signal will always use the best path available. Is there a generic term for these trajectories? The HG-5 is a folding relay antenna, it's just not very strong. 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. Polar triangle orbit above 700km. We consider a smaller target orbit, so p With proper resonance, you are in a mapping orbit and can complete grab/temp scans above x contacts without fuel burn. If you like, you can add a command to maintain attitude after the burn. 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. Otherwise this scheme is resistant to placement errors. Note: Your post will require moderator approval before it will be visible. Is it safe to publish research papers in cooperation with Russian academics? Type a delay that corresponds to just after the orbit insertion is finished (any attitude commands sent during the burn will be ignored). Making three trips per body seems like a complete waste of time and resources when these satellites weight so little. Really like the design of your quad-probe. How many relay satellites in what kind of orbits around Kerbin do you need to ensure you always have a connection to the KSC? Why did DOS-based Windows require HIMEM.SYS to boot? What does "Smote their breasts" signify in Luke 23:48? Is there a way to calculate my launch interval (knowing how many satellites in the constellation, orbital period, and apoapsis/periapsis) so I wind up with an equally spaced constellation? There are two ways to avoid this, depending on your play style: following a steep launch path or using the flight computer. Given the nature of orbits, this wouldnt be too much of a problem since the satellite would come back around again, except that on that first crucial launch, you need control to circularize your orbit. 2023 Take-Two Interactive Software, Inc. Back before they made a real atmosphere I frequently sent up 5 satellites at a time, 4 radially and 1 on the front. Your satellite may just not be powerful enough to be better than Kerbin ground stations. With a 2G antenna on probe, this should give you complete coverage within planetary spheres of influence. New comments cannot be posted and votes cannot be cast. Showing 1 - 13 of 13 comments Some trial and error may be necessary if youre used to shallower launches, but the traditional 45 ascent path should work. All trademarks are property of their respective owners in the US and other countries. However, I was wondering, in what circumstances does your vessel bounce its signal off a relay satellite? To establish this link, you require an antenna that has the range to reach it and no obstructions between them. 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. I think I have a pic around here somewhere I'll try to dig it up and update this post with it. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. All rights reserved. The orbital altitude must be greater than the radius of the body you are orbiting. New comments cannot be posted and votes cannot be cast. A set of 24 evenly spaced satellites at around 50,000,000km. Use RA-2 relays. :D. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. what's wrong here? Adding additional relay rings around Kerbol should also help with coverage. Equatorial triangle orbit above 210km. You can match that with 4 relays on one probe, or you can double it with 8. Equatorial triangle orbit above 320km. English version of Russian proverb "The hedgehogs got pricked, cried, but continued to eat the cactus". These relays are for connecting with deep space probes. Yeah, I like parts, so I have mostof them. SpanishInquisitor27 4 yr. ago They are 100G, but noted, thanks. The pod is a little tiny 1-kerbal unit that is perfect for small landers from one of the Umbra Space Industries mods. That way, you wont have to worry about running out of power while halfway around Kerbin. 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. 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. 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). 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 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). That still didn't work. A minor scale definition: am I missing something? Period of Kerbin orbit k = 426 days. Cookie Notice So how do you launch and control the very satellites that are supposed to help you do the controlling? 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. Does the 500-table limit still apply to the latest version of Cassandra? Method 1: Steep Ascent. If you dont want the full Life support experiance make sure you disable food/water/o2 ect in the mod options in the menu system. Yes, that's how combine works. Connect and share knowledge within a single location that is structured and easy to search. Thanks for that. Suppose you want to put three relay satellites into circular polar orbit around Minmus. two satellites line up and both get occluded by Mun/Minmus, and the last one gets occluded by the other one. 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. Pasted as rich text. Since Kerbin is faster than, say, Jool, the second satellite you launch will end up forward the first anyway. Its antenna is an HG-5. 2 Satelites in matching orbits in opposite ends of eachother. Another thing to consider is polar relays are great for many things: > Anomaly detection over several days (at sufficiently high altitude you can see the entire planet face in Kerb net). 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. I basically do what @Geonovast posted. Polar triangle orbit above 210km. I have too many KSP screenshots. 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.
