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. Minmus Relay Satellites : r/KerbalAcademy - Reddit Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Polar orbit above 6,000km. It assumes you have not yet established a comsat network, so that the only connection of interest is a direct link between the . Has depleted uranium been considered for radiation shielding in crewed spacecraft beyond LEO? Ok cool, thanks for the help guys! Thanks, found the answer. Use RA-100 relays. Anyway, worth mentioning is that this is a very inefficient way to do a relay satellite. You just made my KSP save a whole lot cooler. Relay Satellites are used to communicate with the Kerbal Space Center without the need for a direct connection to it. 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. Left: A comlink-friendly ascent path. To clarify, I understand the irl counterpart to a relay Network I'm more wondering if they're actually useful/needed in the game. 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. Does the 500-table limit still apply to the latest version of Cassandra? This satellite is in visual range of KSC. 2023 Take-Two Interactive Software, Inc. Researching Electrics, which unlocks solar panels, is recommended but not required. I basically do what @Geonovast posted. Why has my Command Module's orbit not decayed? You usually put a relay antennae in orbit of a planet so you can bounce a signal from the KSC to a place where it normally would not be able to reach, such as the side of the moon opposite kerban where line of sight is blocked by the moon or on a distant planet where the signal cannot normally reach. The DP-10s main disadvantage is its 500 km range. Circle The period is the same as the target orbital period. Also one RA-2 can reach anywhere in kerbin's SOI that it has line of sight to, at least out to Minmus orbit. Why did DOS-based Windows require HIMEM.SYS to boot? I somehow missed interstage nodes since they were added ages ago, and haven't seen them in any videos that I can remember. how to plan pre-network missions around your limited line of sight to KSC. Every time it passes over KSC, you can send or schedule more commands. Actually I never have figured out a way to tell exactly how many Gs are had by a relay sat with multiple antennas. What's the difference between probes and relays? 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. 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 ! That way, you wont have to worry about running out of power while halfway around Kerbin. Which gives t = p/(4(1 - p/k)) 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. It's reasonably accurate over close-ish values to take the average, but the actual math is the square root of (the first vessel's power x the second vessel's power). So the actual separation, in time, is actually t - t2 = t - t*p/k = t*(1 - p/k). I figure I could add 20 days to the launch window (launch every 66 days). The pod is a little tiny 1-kerbal unit that is perfect for small landers from one of the Umbra Space Industries mods. Now warp to your Ap and deploy the first relay. Use RA-2 relays. I like to stack multiple satellites per level, as shown below (those are smaller sats of course, but the same concept applies). KerbalX - KSP Craft Sharing Simplified Polar triangle orbit. With a 2G antenna on probe, this should give you complete coverage within planetary spheres of influence. Could a subterranean river or aquifer generate enough continuous momentum to power a waterwheel for the purpose of producing electricity? The gold parts are Procedural Parts batteries. Weaker signal (network paths shown) A Screenshot of Kerbal Space Program. 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. Polar triangle orbit above 700km. Setting the target now will give you one less thing to worry about in the hectic minute before orbital insertion. How Does Power Effect Relays? :: Kerbal Space Program General Discussions Privacy Policy. Use RA-2 relays. 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. Polar triangle orbit above 250km. 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. And what on the Probe around the Mun? 2. SpanishInquisitor27 4 yr. ago Squad might want to make that necessity a little more clear. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. 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. With the addition of CommNet, you need a system of relays to connect back to the KSC. Method 2: Flight Computer. Thanks for that. In order to have remote control of a vessel, it must have a communications link with Kerbal Space Center. One between the orbit of Moho and Eve with four satellites. 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. I looked for the screenshots, no luck. I tried launching one satellite every 46 days, but that didn't work. A quick final note : this answer supposes a series of identical Hohmann transfers for each satellite, and it does not consider elliptical orbits, nor modulos of orbital period. 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. Equatorial triangle orbit above 250km. There is also an advanced difficulty setting where you don't have stations all over Kerbin but only have the KSC. Creating a satellite Start with an RC-001S probe core Underneath, add a reaction wheel and a few z-1k battery banks Add some Gigantor-XL solar panels around the outside. Equatorial triangle orbit above 600km. 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. Was Aristarchus the first to propose heliocentrism? But adding it 40 degrees away is OK and will prevent occlusion from Mun/Minmus.). For most practical applications an easy solution is to have a ring of three evenly spaced satellites in high (2500km-7000km) circular equatorial orbits. Some trial and error may be necessary if youre used to shallower launches, but the traditional 45 ascent path should work. Any other Suggestions you may have! I am trying to deploy three relay satellite constellations. Making three trips per body seems like a complete waste of time and resources when these satellites weight so little. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Otherwise you risk launching nothing but a future fireworks display for the citizens on the far side of Kerbin. How do I view my network? Relay refers to the relay type antennae. 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. Use mod filters to select craft that; will work With selected mods. Should have a short-range dish pointed at Kerbin, to connect to the low-orbit network, and one or more long-range dishes pointed at the destination planet (s). That factor goes negative, so you should launch back in time ? So four 15G communication dishes on one sathave a range of 42 gm, which if I recall covers everything but Jool and Eeloo. r/KerbalSpaceProgram on Reddit: KSP Relay Network Guide You can get more details in this KSP forum post, which takes it from this research paper (paywall). You then need to have (for 8 satellites) p/8 = t*(p/k - 1) with t the time between launches. Why do men's bikes have high bars where you can hit your testicles while women's bikes have the bar much lower? On what basis are pardoning decisions made by presidents or governors when exercising their pardoning power? I thought the gold bit was a probe core, but it's the wrong shape. What are the advantages of running a power tool on 240 V vs 120 V? Polar triangle orbit above 600km. And so far, signal will always use the best path available. Really like the design of your quad-probe. 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). Reddit and its partners use cookies and similar technologies to provide you with a better experience. Factor of division = 1 - 184 / 426 = 0.568 Adding EV Charger (100A) in secondary panel (100A) fed off main (200A), Generic Doubly-Linked-Lists C implementation. Here's how to set up a constellation of satellites to ensure complete coverage. Blind spots: Having a ring of satellites leaves blind spots on the surface (poles in case of equatorial ring). rev2023.4.21.43403. Relay satellites and probe control :: Kerbal Space Program General 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. 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? Antenna - Kerbal Space Program Wiki Its antenna is a Communotron 16. Connect and share knowledge within a single location that is structured and easy to search. 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. If you put the relays on opposite sides of a highly elliptical polar orbit, you should have very little loss of signal time. It looks more or less stock to me, although on close inspection it has some fiddly bits I can't quite identify. With update 1.2, you need to make sure that probes always have a communication link to Kerbin. By: AlexMBrennan. 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. 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. ', referring to the nuclear power plant in Ignalina, mean? 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. To play this tutorial, you should already know how to launch non-RemoteTech rockets, including basic rocket design, staging, and using maneuver nodes. "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. 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. Launch however you usually do. Use RA-15 relays. Why do men's bikes have high bars where you can hit your testicles while women's bikes have the bar much lower? 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. If you have the Comms DTS-M1, right-click on it while on the launchpad, then click the button marked No Target. I've just started playing 1.2, loving it so far! And for total coverage do triple relay sat launches for the Mun and Minmus. Of course the trouble in KSP doesn't have Lagrange points (which is what Queqiao orbits). 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. How do I stop the Flickering on Mode 13h? This tutorial covers the basics of launching a standalone satellite in RemoteTech. English version of Russian proverb "The hedgehogs got pricked, cried, but continued to eat the cactus". It only takes a minute to sign up. Cookie Notice About 3000g orbiting outside Minmus. Really like the design of your quad-probe. 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. Period of Kerbin orbit k = 426 days. Let's say p is the period of your target orbit and k the period of Kerbin orbit. Effect of a "bad grade" in grad school applications. Equatorial triangle orbit above 138km. and our Parabolic, suborbital and ballistic trajectories all follow elliptic paths. This is useful for setting up things like CommNet constellations. is there such a thing as "right to be heard"? For an inner orbit (pKSP 1.2: How To Create a Geostationary Relay Network I'm using two HG-5 High Gain Antennae (class 3) on my relay and the Communotron 15 (class 2) on my lander. You can do the same on upper levels using cubic octagonal struts to create extra nodes). 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. I use stock parts pretty rarely. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. Your launch trajectory is important. A relay satellite must have at least one relay-capable antenna and a probe core. Number of satellites - Three satellites are enough to form a complete ring around Kerbin. Method 1: Steep Ascent. and our Is there a weapon that has the heavy property and the finesse property (or could this be obtained)? Use RA-2 relays. If you use CKAN, drop your 'installed-default.ckan' file here to auto select mods explain this. Execute the burn as accurately as possible. Rocket scientist alternative: if you are more of a rocket scientist than me, you can place four satellites in a tetrahedral formation around Kerbin. I think I have a pic around here somewhere I'll try to dig it up and update this post with it. 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. This is a small cost to do and allows you to range much further than KSC can pull off. Why don't we use the 7805 for car phone chargers? ], Maintaining control during probe atmospheric landing with RemoteTech. Yes, that's how combine works. Although I am checking in version 1.5, so they might have new skins in later versions. Period of target orbit p = 184 days Dont forget to reset the delay to 0 when youre done! Solves a lot of problems. 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). 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. The DP-10 is unique among RemoteTech antennas in that it is automatically switched on at mission start, so you dont need to do any fine-tuning on the pad. 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! For ever-higher orbits, you will only be in range in an ever-narrower circle centered on Mission Control. Did the Golden Gate Bridge 'flatten' under the weight of 300,000 people in 1987? A set of 24 evenly spaced satellites at around 50,000,000km. For more information, please see our Have you checked if the two antennas are in range to communicate with each other? 3 Satellites in an equal orbit forming an equalateral triangle with eachother. 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). Scan this QR code to download the app now. Doesn't save mass, but it does allow for SLIGHTLY longer satellites. Equatorial triangle orbit above 13km. Could someone explain that as well? 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. kerbal space program - How to build a satellite network around Kerbin 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. Once you get the really big satellite dishes, the signal will always bounce off that. All trademarks are property of their respective owners in the US and other countries. 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. I would like the satellites in each constellation to be equally spaced. 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. A second equatorial triangle orbit at around 60,000km. Archived post. How can I control PNP and NPN transistors together from one pin? If you have solar panels, deploy them as soon as you are out of the atmosphere, even if its a night launch. Use RA-100 relays. How to build a Satellite Network? - KSP1 Gameplay Questions and Use RA-2 relays. If you are launching with solar panels, you should already know how to deploy them. Is there a generic term for these trajectories? 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. If not, is there a mod or config option to make folding antennas work as relays? This means tuning your launch trajectory so that you finish your final burn less than 280 km (27 longitude) downrange of KSC. (A spacecraft consisting of a pilot would not be affected.) It's not them. Three panels is enough for near Kerbin, but you'll need more if you go farther out. All rights reserved. Tutorial:Setting up a CommNet system - Kerbal Space Program You can also slightly rotate the two bottom satellites so they are more "next to" each other than facing off. Espaol - Latinoamrica (Spanish - Latin America), https://en.wikipedia.org/wiki/Tundra_orbit. :D. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. 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). Can't remember if those or stock or not. We consider a smaller target orbit, so p
