Which gives t = p/(4(1 - p/k)) You now have a basic satellite in orbit around Kerbin. how to plan pre-network missions around your limited line of sight to KSC. 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. In order to have remote control of a vessel, it must have a communications link with Kerbal Space Center. I looked for the screenshots, no luck. 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. To establish this link, you require an antenna that has the range to reach it and no obstructions between them. If that's the case, then you have to replicate the extra ground stations in space with a ring of relays around Kerbin. 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. Note: Your post will require moderator approval before it will be visible. "beep beep beep beep" - Leonard Nimoy, using the flight computer to get into orbit, how to keep control of unmanned rockets from liftoff to orbit. It looks more or less stock to me, although on close inspection it has some fiddly bits I can't quite identify. Reddit and its partners use cookies and similar technologies to provide you with a better experience. Relay satellites and probe control :: Kerbal Space Program General KSP 1.2: How To Create a Geostationary Relay Network 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. You can post now and register later. Check that the Delay (+ signal) display reads one minute. If the satellites are high up the spots will be really small, but any terrain irregularities close to them will easily block the signal. > I like to use my polar relay as a synchronization timer in case my Draim constellation desynchronizatizes. Post-Burn Attitude Control. Relay Satellites are used to communicate with the Kerbal Space Center without the need for a direct connection to it. Browse other questions tagged, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site. 8 direct antennas therefore, will then double communication range for transmitting data. ', referring to the nuclear power plant in Ignalina, mean? 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. So the actual separation, in time, is actually t - t2 = t - t*p/k = t*(1 - p/k). Calculate Satellite Constellation Launch Interval, Improving the copy in the close modal and post notices - 2023 edition, New blog post from our CEO Prashanth: Community is the future of AI, Screenshot of the Week #89 [Submissions Closed, Vote Now!]. Equatorial triangle orbit above 600km. Cookie Notice Equatorial - This system has blind spots on the surface. But adding it 40 degrees away is OK and will prevent occlusion from Mun/Minmus.). The best way to get multiple sats in one launch is to use the "Interstage Nodes" option on the fairings, which will let you attach multiple stacked payloads without them touching. I tried launching one satellite every 46 days, but that didn't work. Although I am checking in version 1.5, so they might have new skins in later versions. Its antenna is an HG-5. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. Its just a matter of being careful. High-Powered Antennas. Use RA-2 relays. Effect of a "bad grade" in grad school applications. 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. 2023 Take-Two Interactive Software, Inc. Adding EV Charger (100A) in secondary panel (100A) fed off main (200A). 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. Improving the copy in the close modal and post notices - 2023 edition, New blog post from our CEO Prashanth: Community is the future of AI, Screenshot of the Week #89 [Submissions Closed, Vote Now! New comments cannot be posted and votes cannot be cast. Was Aristarchus the first to propose heliocentrism? Rocket scientist alternative: if you are more of a rocket scientist than me, you can place four satellites in a tetrahedral formation around Kerbin. Thank you. Can't remember if those or stock or not. 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. Deep space coverage may not be perfect. I thought the gold bit was a probe core, but it's the wrong shape. A set of twelve evenly spaced relays at around 25,000,000km. 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 you have an account, sign in now to post with your account. You build relays satellites at the target not the source, they don't do anything orbiting kerbin. How Does Power Effect Relays? :: Kerbal Space Program General Discussions For the first, I settled on an orbital altitude of 7.5Gm. Squad might want to make that necessity a little more clear. KSC only boasts 250G. 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. Type a delay that corresponds to just after the orbit insertion is finished (any attitude commands sent during the burn will be ignored). The pod is a little tiny 1-kerbal unit that is perfect for small landers from one of the Umbra Space Industries mods. With that option on, each probe requires either direct line of sight to the KSC or to a communication satellite which has a connection. Its ok if you do this while still in the atmosphere. At low tech levels you have access to only three antennas: the Communotron 16, the Reflectron DP-10, and the Comms DTS-M1. (A spacecraft consisting of a pilot would not be affected.) Any other Suggestions you may have! 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. 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? Use mod filters to select craft that; will work With selected mods. Solves a lot of problems. If you use CKAN, drop your 'installed-default.ckan' file here to auto select mods explain this. I have decided I want to launch multiple scientific hopper probes to Minmus, however in order to do this I will need to relay the probes through a satelite in order to mauntain control, these probes are intended to go to all of the biomes if Minmus including the poles, I have considered a few different satellite configurations for this and I would like to know what the benefits of each of them are. Or you can just leave it where it is, happily beeping away. Scan this QR code to download the app now. It's not them. Weaker signal (network paths shown) A Screenshot of Kerbal Space Program. 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. Bear in mind that when it's acting as a relay, it's running on rails (unless you happen to have your currently-piloted ship parked right next to it, inside the physics bubble), which means that it doesn't actually use up electricity while it's running. 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. Launch. 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). How to build a Satellite Network? - KSP1 Gameplay Questions and How many relay satellites in what kind of orbits around Kerbin do you need to ensure you always have a connection to the KSC? The HG-5 is a folding relay antenna, it's just not very strong. All rights reserved. https://wiki.kerbalspaceprogram.com/index.php?title=Relay_Satellite&oldid=104907. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Yes, that's how combine works. rev2023.4.21.43403. That still didn't work. Why do men's bikes have high bars where you can hit your testicles while women's bikes have the bar much lower? Rather than opening instantly, the solar panels will appear in the queue, scheduled to open after the delay. You can match that with 4 relays on one probe, or you can double it with 8. Factor of division = 1 - 184 / 426 = 0.568. Archived post. One between the orbit of Moho and Eve with four satellites. 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. On what basis are pardoning decisions made by presidents or governors when exercising their pardoning power? This satellite is in visual range of KSC. 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. Upload or insert images from URL. Use RA-100 relays. With 20 x 100GM satellites, you'd have a power of 945 GM and you'd be able to talk to a level 3 tracking station from 486 GM or to a probe with NO antenna and only the 5k onboard from about 68 MM - within the kerbin SOI, for example. Send a couple small relay satellites with your probe. One long-range relay satellite in a very eccentric near-polar orbit (~80 km periapsis, ~80,000 km apoapsis, inclination near poles). Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. 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. Which gives t = p/(8(p/k - 1)). That way, you wont have to worry about running out of power while halfway around Kerbin. 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). This tutorial covers the basics of launching a standalone satellite in RemoteTech. Doesn't save mass, but it does allow for SLIGHTLY longer satellites. Your link has been automatically embedded. So four 15G communication dishes on one sathave a range of 42 gm, which if I recall covers everything but Jool and Eeloo. If you are launching with solar panels, you should already know how to deploy them. 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. Use RA-2 relays. A relay satellite must have at least one relay-capable antenna and a probe core. How to achive a highly eccentric polar orbit around the sun oriented orthogonal to the ecliptic? ], Maintaining control during probe atmospheric landing with RemoteTech. I got the same answer from the KSP fora, but with minimal explanation of the underlying math. The large solar panels sort of look like Gigantor arrays maybe on pipes or actuators? Thanks, found the answer. Resonant Orbit Calculator v1.4 - KSP1 Tutorials - Kerbal Space Program Tutorial:Setting up a CommNet system - Kerbal Space Program Archived post. Thanks for that. I somehow missed interstage nodes since they were added ages ago, and haven't seen them in any videos that I can remember. What's the difference between probes and relays? 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 best answers are voted up and rise to the top, Not the answer you're looking for? is there such a thing as "right to be heard"? The contract is to send a satellite with an appropriate dish or combination of dishes into an orbit low enough that surface missions can use the whip antenna instead of having to pack a big dish (so long as a relay is overhead, of course). This means tuning your launch trajectory so that you finish your final burn less than 280 km (27 longitude) downrange of KSC. 2. 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. 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. If you want probes at the poles, one solution is to just have another ring in a polar orbit. How do I view my network? This satellite is out of control . 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. How do I stop the Flickering on Mode 13h? If total energies differ across different software, how do I decide which software to use? 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 rev2023.4.21.43403. If you put the relays on opposite sides of a highly elliptical polar orbit, you should have very little loss of signal time. They are 100G, but noted, thanks. Adding additional relay rings around Kerbol should also help with coverage. Use RA-100 relays. And so far, signal will always use the best path available. Didn't know about having to enable the option. Such a formation will provide coverage on all of Kerbin's surface and cannot get fully occluded by Mun/Minmus. If you have the Comms DTS-M1, right-click on it while on the launchpad, then click the button marked No Target. Learn more about Stack Overflow the company, and our products. Otherwise this scheme is resistant to placement errors. Why do men's bikes have high bars where you can hit your testicles while women's bikes have the bar much lower? Could someone explain that as well? 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. Otherwise you risk launching nothing but a future fireworks display for the citizens on the far side of Kerbin. 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. 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. Placing the satellites in a roughly equatorial orbit leaves the blind spots at the poles (our main concern is that the KSC does not get into the blind spot). How can I control PNP and NPN transistors together from one pin? Not to mention transmitting grav scans for every biome! 2023 Take-Two Interactive Software, Inc. Of course the trouble in KSP doesn't have Lagrange points (which is what Queqiao . 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. For more information, please see our Polar triangle orbit above 320km. Learn more about Stack Overflow the company, and our products. To control a probe or satellite from the ground, you need a reliable communications link over which to send commands to mission control. Satellite exploding while in transfer orbit. (I recommend the decoupler be set to 0 force so your orbits don't change when you detach.) To clarify, I understand the irl counterpart to a relay Network I'm more wondering if they're actually useful/needed in the game. 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. For more information, please see our Use RA-2 relays. Your second probe might have some visual mods, or maybe some custom dish parts because I don't see a stock dish that looks exactly like those dishes do Ditto your forward solar panels; they either look like custom textures for the 3x2 stock panel, or custom parts. All trademarks are property of their respective owners in the US and other countries. Why did DOS-based Windows require HIMEM.SYS to boot? With a 2G antenna on probe, this should give you complete coverage within planetary spheres of influence. 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. Circle The period is the same as the target orbital period. Method 2: Flight Computer. Also one RA-2 can reach anywhere in kerbin's SOI that it has line of sight to, at least out to Minmus orbit. The gold parts are Procedural Parts batteries. I did a six-lander Mun invasion once, with landers very similar to what you see above stacked six high with stack separators between each and an orbital maneuvering stage with lots of Dv for multiple plane changes. Polar triangle orbit above 60km. Why are players required to record the moves in World Championship Classical games? 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 ! Clear editor. Using an Ohm Meter to test for bonding of a subpanel. 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. Some trial and error may be necessary if youre used to shallower launches, but the traditional 45 ascent path should work. Satellites are not connecting to each other :: Kerbal Space Program 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. You cannot paste images directly. I'm using two HG-5 High Gain Antennae (class 3) on my relay and the Communotron 15 (class 2) on my lander. 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. You can also slightly rotate the two bottom satellites so they are more "next to" each other than facing off. Use RA-15 relays. What's the difference between relay and direct antennas? :: Kerbal Type 1m (for one minute, or whatever delay you think you need to be clear of that pesky air) in the lower right text box, then press enter. Setting the target now will give you one less thing to worry about in the hectic minute before orbital insertion. (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. Of course the trouble in KSP doesn't have Lagrange points (which is what Queqiao orbits). Adding EV Charger (100A) in secondary panel (100A) fed off main (200A), Generic Doubly-Linked-Lists C implementation. 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. A set of 24 evenly spaced satellites at around 50,000,000km. These are landers, but it works just as well with satellites. Let's ignore occlusion by Mun and Minmus for now and focus only on what it takes to not get blocked by Kerbin. Actually I never have figured out a way to tell exactly how many Gs are had by a relay sat with multiple antennas. This video tutorial demonstrates how to build, launch and set up a relay satellite network in KSP. 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. 1% signal strength), then it will not switch to using a relay (even if it could boost signal to 99%) until something blocks the direct signal path and forces the sat to switch. 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. Kerbin, Mun and Minmus block one satellite each, or. 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. After t days have passed : Relay not working - KSP1 Technical Support (PC, unmodded installs Making three trips per body seems like a complete waste of time and resources when these satellites weight so little. I am trying to deploy three relay satellite constellations. I would like the satellites in each constellation to be equally spaced. Really like the design of your quad-probe. Equatorial triangle orbit above 138km. Relay refers to the relay type antennae. A triangle orbit will be the main orbit used in the constellations. Please consider starting a new thread rather than reviving this one. All rights reserved. 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. One between Kerbin and Duna with six satellites. 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.
