a normal antenna can connect to a relay antenna or the KSC directly. Polar triangle orbit above 700km. How can I control PNP and NPN transistors together from one pin? 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. Since electricity isn't consumed when a vehicle isn't controlled by the player, electric charge storage and generation isn't required. 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). 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. Making three trips per body seems like a complete waste of time and resources when these satellites weight so little. If you put the relays on opposite sides of a highly elliptical polar orbit, you should have very little loss of signal time. 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. Archived post. When a gnoll vampire assumes its hyena form, do its HP change? I can't see why they wouldn't be able to. I think I have a pic around here somewhere I'll try to dig it up and update this post with it. Optional Steps. 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. Use RA-2 relays. Polar triangle orbit above 600km. On what basis are pardoning decisions made by presidents or governors when exercising their pardoning power? Although I am checking in version 1.5, so they might have new skins in later versions. If you want probes at the poles, one solution is to just have another ring in a polar orbit. 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. What antenna are you using on the relay? Adding EV Charger (100A) in secondary panel (100A) fed off main (200A), Generic Doubly-Linked-Lists C implementation. Equatorial - This system has blind spots on the surface. Connect and share knowledge within a single location that is structured and easy to search. Polar triangle orbit above 320km. That would probably be close enough.

Could a subterranean river or aquifer generate enough continuous momentum to power a waterwheel for the purpose of producing electricity? 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. 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. A triangle orbit will be the main orbit used in the constellations. Relay Satellites are used to communicate with the Kerbal Space Center without the need for a direct connection to it. Execute the burn as accurately as possible. Any clues? The transmission would be 13 packets and consume 78 in 7.8 seconds. 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. 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. Such a formation will provide coverage on all of Kerbin's surface and cannot get fully occluded by Mun/Minmus. It consists of three co-orbital satellites, 120 degrees apart. If the satellites are high up the spots will be really small, but any terrain irregularities close to them will easily block the signal. For a start, I have placed a relay satellite in KEO. Polar triangle orbit above 130km. How Does Power Effect Relays? :: Kerbal Space Program General Discussions Deep space coverage may not be perfect. Unfortunately, a path like that means you wont reach orbit until you are out of sight of Mission Control, and therefore out of contact. I am trying to deploy three relay satellite constellations. After t days have passed : I thought the gold bit was a probe core, but it's the wrong shape. Otherwise you risk launching nothing but a future fireworks display for the citizens on the far side of Kerbin. This satellite is out of control . 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). I thought the gold bit was a probe core, but it's the wrong shape. 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. However many Life Support mods will allow power drain from inactive crafts. That factor goes negative, so you should launch back in time ? How to build a satellite network around Kerbin which guarantees full coverage? This page was last edited on 24 March 2023, at 18:10.

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. Ok cool, thanks for the help guys! how to plan pre-network missions around your limited line of sight to KSC. Why did DOS-based Windows require HIMEM.SYS to boot? All trademarks are property of their respective owners in the US and other countries. Can't remember if those or stock or not. What does "Smote their breasts" signify in Luke 23:48? Blind spots: Having a ring of satellites leaves blind spots on the surface (poles in case of equatorial ring). English version of Russian proverb "The hedgehogs got pricked, cried, but continued to eat the cactus". Period of Kerbin orbit k = 426 days Thanks for that. Is it safe to publish research papers in cooperation with Russian academics? Polar triangle orbit above 60km. Privacy Policy. Doesn't save mass, but it does allow for SLIGHTLY longer satellites. 184 / (4*0.568) = 81 days. If you like, you can add a command to maintain attitude after the burn. Your launch trajectory is important. Launch. The relay sats don't need much v - just enough to put them in the orbit you want after you get to Eve.

It looks more or less stock to me, although on close inspection it has some fiddly bits I can't quite identify. Dedicated to the growth and advancement of amateur rocket scientists! Adding EV Charger (100A) in secondary panel (100A) fed off main (200A). It only takes a minute to sign up. Cookie Notice Period of target orbit p = 184 days 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. Also, it's interesting to see that in the case of p = k, the calculations divides by 0 ! 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. 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 final queue should look something like this picture (the Toggle SAS command is optional). This video tutorial demonstrates how to build, launch and set up a relay satellite network in KSP. All rights reserved. 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. They are 100G, but noted, thanks. KerbalX - KSP Craft Sharing Simplified Connect and share knowledge within a single location that is structured and easy to search. It brought me ~30-40 days separation. High-Powered Antennas. 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. Equatorial triangle orbit above 600km. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. And what on the Probe around the Mun? 8 direct antennas therefore, will then double communication range for transmitting data. Dont forget to reset the delay to 0 when youre done! Tutorial - First Satellite - GitHub Pages 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! One between Dres and Jool with eight satellites. Squad might want to make that necessity a little more clear. 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 13km. Weaker signal (network paths shown) A Screenshot of Kerbal Space Program. Solves a lot of problems. kerbal space program - Calculate Satellite Constellation Launch I want to send a probe to Eve as this is my first planetary mission and I'd rather not risk kerbals. Is there a weapon that has the heavy property and the finesse property (or could this be obtained)? Suppose you want to put three relay satellites into circular polar orbit around Minmus. SpanishInquisitor27 4 yr. ago 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). Espaol - Latinoamrica (Spanish - Latin America), https://en.wikipedia.org/wiki/Tundra_orbit. Polar triangle orbit above 138km. For the first, I settled on an orbital altitude of 7.5Gm. two satellites line up and both get occluded by Mun/Minmus, and the last one gets occluded by the other one. You can match that with 4 relays on one probe, or you can double it with 8. and our Use RA-2 relays.

Its just a matter of being careful. Circular orbit - Just easier to work with (and to do the math). Let's say p is the period of your target orbit and k the period of Kerbin orbit. Reddit and its partners use cookies and similar technologies to provide you with a better experience. Select mods using text field above and KerbalX will find craft that use those mods. Satellites are not connecting to each other :: Kerbal Space Program Which gives t = p/(4(1 - p/k)) For ever-higher orbits, you will only be in range in an ever-narrower circle centered on Mission Control. Resonant Orbit Calculator (Kerbal Space Program) Resonant Orbit Calculator Calculate the resonant orbit needed for a carrier craft to inject craft it carries, like satellites, into equidistant positions of a shared circular orbit. This video tutorial demonstrates how to build, launch and set up a relay satellite network in KSP. All rights reserved. Rather than opening instantly, the solar panels will appear in the queue, scheduled to open after the delay. 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. Three panels is enough for near Kerbin, but you'll need more if you go farther out. Arqade is a question and answer site for passionate videogamers on all platforms. For most practical applications an easy solution is to have a ring of three evenly spaced satellites in high (2500km-7000km) circular equatorial orbits. How much electricity does a relay satellite use? That way, you wont have to worry about running out of power while halfway around Kerbin. "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. Use RA-2 relays. Which gives t = p/(8(p/k - 1)). 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. 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. 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 view my network? A set of 24 evenly spaced satellites at around 50,000,000km. Polar triangle orbit above 200km. I'm using two HG-5 High Gain Antennae (class 3) on my relay and the Communotron 15 (class 2) on my lander. If your satellite will never go above 150 km, this is more than adequate any time you have a line of sight to Mission Control, you will be in range. Why do men's bikes have high bars where you can hit your testicles while women's bikes have the bar much lower? How to combine several legends in one frame? The pod is a little tiny 1-kerbal unit that is perfect for small landers from one of the Umbra Space Industries mods. Learn more about Stack Overflow the company, and our products. Check that the Delay (+ signal) display shows no delay. Mun/Minmus occlusion: All the satellites can get occluded when either. Unexpected uint64 behaviour 0xFFFF'FFFF'FFFF'FFFF - 1 = 0? 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!]. 1 Relay Satelite in Stationary orbit in the Center of the light side of Minmus. There is also an advanced difficulty setting where you don't have stations all over Kerbin but only have the KSC. One long-range relay satellite in a very eccentric near-polar orbit (~80 km periapsis, ~80,000 km apoapsis, inclination near poles). Tutorial - Interplanetary Networks 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). So four 15G communication dishes on one sathave a range of 42 gm, which if I recall covers everything but Jool and Eeloo. Fortunately, getting into a stable orbit before you lose control doesnt demand any precision computing. It only takes a minute to sign up. However, I have this other satellite which is out of contact with KSC, but in visual range of the relay satellite. 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. 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. Adding additional relay rings around Kerbol should also help with coverage. The other two antennas are optional for low enough orbits. How do I stop the Flickering on Mode 13h? Was Aristarchus the first to propose heliocentrism? Privacy Policy. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. You cannot paste images directly. Setting the target now will give you one less thing to worry about in the hectic minute before orbital insertion. 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.. Effect of a "bad grade" in grad school applications. 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. Once you get the really big satellite dishes, the signal will always bounce off that. Some trial and error may be necessary if youre used to shallower launches, but the traditional 45 ascent path should work. Satellite exploding while in transfer orbit. Why are players required to record the moves in World Championship Classical games? The End. The best answers are voted up and rise to the top, Not the answer you're looking for? r/KerbalSpaceProgram on Reddit: KSP Relay Network Guide rev2023.4.21.43403. Then, open the flight computer by clicking on the calculator icon below the mission clock, followed by to open the command queue. If total energies differ across different software, how do I decide which software to use? 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. 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. Why has my Command Module's orbit not decayed? If you have the Comms DTS-M1, right-click on it while on the launchpad, then click the button marked No Target. > I like to use my polar relay as a synchronization timer in case my Draim constellation desynchronizatizes. 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 ! This tutorial does not require any mods other than RemoteTech. This tutorial covers the basics of launching a standalone satellite in RemoteTech. A second equatorial triangle orbit at around 300,000km. For more information, please see our Equatorial triangle orbit above 250km. This means tuning your launch trajectory so that you finish your final burn less than 280 km (27 longitude) downrange of KSC. 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. Use RA-2 relays. Relay Satellites are used to communicate with the Kerbal Space Center without the need for a direct connection to it. 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. Then open each panel by right-clicking or using an action group, as in normal KSP. 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 : For more information, please see our This page was last edited on 19 July 2020, at 20:55. What does 'They're at four. About 3000g orbiting outside Minmus. 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. New comments cannot be posted and votes cannot be cast. Resonant Orbit Calculator (Kerbal Space Program) - meyerweb.com By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. 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. I like to stack multiple satellites per level, as shown below (those are smaller sats of course, but the same concept applies). Has depleted uranium been considered for radiation shielding in crewed spacecraft beyond LEO? 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. KSP 1.2: How To Create a Geostationary Relay Network Actually I never have figured out a way to tell exactly how many Gs are had by a relay sat with multiple antennas. 3 Satellites in an equal orbit forming an equalateral triangle with eachother. 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. This satellite is in visual range of KSC. Circle The period is the same as the target orbital period. You then need to have (for 8 satellites) p/8 = t*(p/k - 1) with t the time between launches. Minmus Relay Satellites : r/KerbalAcademy - Reddit Use RA-2 relays. Relay satellites are exceptionally useful if put into a suitable type of Orbit according to the circumstance. Valve Corporation. 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. Multi-Satellite Launches - Kerbal Space Program Forums 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. If not, is there a mod or config option to make folding antennas work as relays? Reddit and its partners use cookies and similar technologies to provide you with a better experience. These relays are for connecting with deep space probes. You just made my KSP save a whole lot cooler. To clarify, I understand the irl counterpart to a relay Network I'm more wondering if they're actually useful/needed in the game. Could someone explain that as well? And for total coverage do triple relay sat launches for the Mun and Minmus. The satellite is on the same side of the mun as the probe and has full signal from Kerbin. Resonant Orbit Calculator v1.4 - KSP1 Tutorials - Kerbal Space Program Equatorial triangle orbit above 6,000km. The large solar panels sort of look like Gigantor arrays maybe on pipes or actuators? If that's the case, then you have to replicate the extra ground stations in space with a ring of relays around Kerbin. How can I control PNP and NPN transistors together from one pin? 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). Relay refers to the relay type antennae. You may omit the third ring but deep space coverage in the outer system may be a bit spotty. :D. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. A high orbit is easier to work with. What's the difference between probes and relays? Yeah, I like parts, so I have mostof them. It looks more or less stock to me, although on close inspection it has some fiddly bits I can't quite identify. As for any KSP probe, you will need a probe core, a battery, and (once you have the tech) solar panels. 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. What's the difference between relay and direct antennas? :: Kerbal Will I need to set up a relay Network to do this? Use RA-2 relays. Equatorial triangle orbit above 210km.
