Its antenna is a Communotron 16. Really like the design of your quad-probe. Launch. How to build a satellite network around Kerbin which guarantees full coverage? 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. So you see that you should further increase the delay between each launch to 81 days. Its just a matter of being careful. A second equatorial triangle orbit at around 60,000km. With a 15G antenna, you get much better deep space coverage.

Why do men's bikes have high bars where you can hit your testicles while women's bikes have the bar much lower? 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 give the function for other Probes to stay connected to the Kerbal Space Center without having the requirement to be in the line of Kerbin, or the range. 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. These relays are for connecting with deep space probes. Since electricity isn't consumed when a vehicle isn't controlled by the player, electric charge storage and generation isn't required. If the satellites are high up the spots will be really small, but any terrain irregularities close to them will easily block the signal. This page was last edited on 24 March 2023, at 18:10. About 3000g orbiting outside Minmus. 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. Once you are coasting to apoapsis, set a maneuver node to represent the final burn to reach orbit. And for total coverage do triple relay sat launches for the Mun and Minmus. This satellite is out of control . Now warp to your Ap and deploy the first relay. You can get more details in this KSP forum post, which takes it from this research paper (paywall). I like to stack multiple satellites per level, as shown below (those are smaller sats of course, but the same concept applies). They are 100G, but noted, thanks. I see in the manual it says the distance for the stock antenna (in command modules and probe cores, class 0) is 5km, and 50km for class 1 and 158km for class 3. 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. 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). Use RA-2 relays. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. 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). 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. There is also an advanced difficulty setting where you don't have stations all over Kerbin but only have the KSC. Deep space coverage may not be perfect. Use RA-2 relays. Use RA-100 relays. Polar triangle orbit above 138km. Relay antennas are exclusively non-foldable, so has anyone come up with a way to fit more than one relay satellite onto a rocket without using huge parts? Setting the target now will give you one less thing to worry about in the hectic minute before orbital insertion. I thought the gold bit was a probe core, but it's the wrong shape. Why don't we use the 7805 for car phone chargers? Connect and share knowledge within a single location that is structured and easy to search. 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? Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. The best answers are voted up and rise to the top, Not the answer you're looking for? 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. (I recommend the decoupler be set to 0 force so your orbits don't change when you detach.) 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. Its antenna is an HG-5. Your link has been automatically embedded. Reddit and its partners use cookies and similar technologies to provide you with a better experience. Researching Electrics, which unlocks solar panels, is recommended but not required. 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. Use RA-2 relays. 3 Satellites in an equal orbit forming an equalateral triangle with eachother, 1 Relay Satelite in Stationary orbit in the Center of the light side of Minmus, 2 Satelites in matching orbits in opposite ends of eachother. Use RA-100 relays. And so far, signal will always use the best path available. 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. Dont forget to reset the delay to 0 when youre done! On 8/28/2019 at 3:51 PM, Cavscout74 said: On 8/30/2019 at 3:57 PM, vossiewulf said: This thread is quite old. Period of Kerbin orbit k = 426 days I would like the satellites in each constellation to be equally spaced. How can I control PNP and NPN transistors together from one pin? By accepting all cookies, you agree to our use of cookies to deliver and maintain our services and site, improve the quality of Reddit, personalize Reddit content and advertising, and measure the effectiveness of advertising. Mun/Minmus occlusion: All the satellites can get occluded when either. and our With update 1.2, you need to make sure that probes always have a communication link to Kerbin. Once you get the really big satellite dishes, the signal will always bounce off that. I want to send a probe to Eve as this is my first planetary mission and I'd rather not risk kerbals. I basically do what @Geonovast posted. Method 1: Steep Ascent. 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. If not, is there a mod or config option to make folding antennas work as relays? Privacy Policy. Interpreting non-statistically significant results: Do we have "no evidence" or "insufficient evidence" to reject the null? Use RA-2 relays. 2 identical dishes have a power of 1.68 times a single dish, and 4 dishes have a power of 2.8 times a single dish. For an inner orbit (p I like to use my polar relay as a synchronization timer in case my Draim constellation desynchronizatizes. Which is a pain so avoid this if at all possible. 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. Learn more about Stack Overflow the company, and our products. Send a couple small relay satellites with your probe. 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. To establish this link, you require an antenna that has the range to reach it and no obstructions between them. Post-Burn Attitude Control. Select mods using text field above and KerbalX will find craft that use those mods. This is a small cost to do and allows you to range much further than KSC can pull off. The best answers are voted up and rise to the top, Not the answer you're looking for? You cannot paste images directly. On what basis are pardoning decisions made by presidents or governors when exercising their pardoning power? How many relay satellites in what kind of orbits around Kerbin do you need to ensure you always have a connection to the KSC? with relay antenna you build your network. What risks are you taking when "signing in with Google". This video tutorial demonstrates how to build, launch and set up a relay satellite network in KSP. By: AlexMBrennan. 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. Let's ignore occlusion by Mun and Minmus for now and focus only on what it takes to not get blocked by Kerbin. A triangle orbit will be the main orbit used in the constellations. Can't remember if those or stock or not. If you use CKAN, drop your 'installed-default.ckan' file here to auto select mods explain this. A second equatorial triangle orbit at around 300,000km. It only takes a minute to sign up. Why are players required to record the moves in World Championship Classical games? Blind spots: Having a ring of satellites leaves blind spots on the surface (poles in case of equatorial ring). Some trial and error may be necessary if youre used to shallower launches, but the traditional 45 ascent path should work. The DP-10s main disadvantage is its 500 km range. But I find it makes sense to put fewer sats on the top, so the fairing can taper around them. 2. Any clues? To clarify, I understand the irl counterpart to a relay Network I'm more wondering if they're actually useful/needed in the game. Equatorial triangle orbit above 700km. Relay antennas are exclusively non-foldable, so has anyone come up with a way to fit more than one relay satellite onto a rocket without using huge parts? Use mod filters to select craft that; will work With selected mods. If you have solar panels, deploy them as soon as you are out of the atmosphere, even if its a night launch. Note that "What you can talk to" depends on the power of BOTH vessels (or the vessel and the tracking station), so if both vessels have the same power, the rated power is the range they can talk. Could someone explain that as well? Polar triangle orbit above 210km. 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. rev2023.4.21.43403. Add a relay satellite on the top ( RA-2, RA-15, or RA-100, depending on range) Done! However many Life Support mods will allow power drain from inactive crafts. 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. With that option on, each probe requires either direct line of sight to the KSC or to a communication satellite which has a connection. Left: A comlink-friendly ascent path. Have you checked if the two antennas are in range to communicate with each other? Such a formation will provide coverage on all of Kerbin's surface and cannot get fully occluded by Mun/Minmus. 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. Could a subterranean river or aquifer generate enough continuous momentum to power a waterwheel for the purpose of producing electricity? Optional Steps. Three panels is enough for near Kerbin, but you'll need more if you go farther out. Equatorial triangle orbit above 320km. Powered by Invision Community. Making three trips per body seems like a complete waste of time and resources when these satellites weight so little. Solves a lot of problems. Please note that this page is incomplete, and requires the help of the community. So the actual separation, in time, is actually t - t2 = t - t*p/k = t*(1 - p/k). That gives an orbital period of roughly 184 days. Polar triangle orbit above 250km. This tutorial does not require any mods other than RemoteTech. All rights reserved. Will keep at it, now I've got a better understanding of CommNet! One between Dres and Jool with eight satellites. Connect and share knowledge within a single location that is structured and easy to search. But adding it 40 degrees away is OK and will prevent occlusion from Mun/Minmus.). Hello- I thought in this play-through it would be fun to set up my own relay satellite network. You build relays satellites at the target not the source, they don't do anything orbiting kerbin. New comments cannot be posted and votes cannot be cast. You can also slightly rotate the two bottom satellites so they are more "next to" each other than facing off. Use RA-2 relays. Valve Corporation. (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. The other two antennas are optional for low enough orbits. Didn't know about having to enable the option. 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. 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. I have bi-coupler and tri-coupler versions also. Method 2: Flight Computer. Thanks, found the answer. You may omit the third ring but deep space coverage in the outer system may be a bit spotty. For most practical applications an easy solution is to have a ring of three evenly spaced satellites in high (2500km-7000km) circular equatorial orbits. Use RA-2 relays. 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. use the relays propulsion to circularise the orbit and match the target orbital period. load your currently installed mods. 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. Polar triangle orbit above 700km. ', referring to the nuclear power plant in Ignalina, mean? Is there a generic term for these trajectories? The second one uses Coatl Aerospace antennas (he has lots of useful antennas) and a bunch of Near Future parts, Solar/Electrical/Construction, and I think some Contares parts too. Did the Golden Gate Bridge 'flatten' under the weight of 300,000 people in 1987? Relay refers to the relay type antennae.
