ksp relay satellite ksp relay satellite

Use RA-100 relays. For ever-higher orbits, you will only be in range in an ever-narrower circle centered on Mission Control. 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. Is there a generic term for these trajectories? 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. Display as a link instead, Polar orbit above 6,000km. Thanks for that. Squad might want to make that necessity a little more clear. 3 Satellites in an equal orbit forming an equalateral triangle with eachother. This is a small cost to do and allows you to range much further than KSC can pull off. Pasted as rich text. Anyway, worth mentioning is that this is a very inefficient way to do a relay satellite. rev2023.4.21.43403. This is so much the right answer. 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). Upload or insert images from URL. If you put the relays on opposite sides of a highly elliptical polar orbit, you should have very little loss of signal time. Use RA-2 relays. Espaol - Latinoamrica (Spanish - Latin America), https://en.wikipedia.org/wiki/Tundra_orbit. To control a probe or satellite from the ground, you need a reliable communications link over which to send commands to mission control. Such a formation will provide coverage on all of Kerbin's surface and cannot get fully occluded by Mun/Minmus. Period of Kerbin orbit k = 426 days The DP-10s main disadvantage is its 500 km range. 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. Scan this QR code to download the app now. 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. 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. Dont forget to reset the delay to 0 when youre done! So there, the separation will be of p*t/k - t, but "forward". To play this tutorial, you should already know how to launch non-RemoteTech rockets, including basic rocket design, staging, and using maneuver nodes. 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). 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. Once you are coasting to apoapsis, set a maneuver node to represent the final burn to reach orbit. 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. 2023 Take-Two Interactive Software, Inc. 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. There are two ways to avoid this, depending on your play style: following a steep launch path or using the flight computer. By: AlexMBrennan. 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). 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. Or, to put it more simply, you have to divide your initial 46 days by the factor 1 - p/k. This video tutorial demonstrates how to build, launch and set up a relay satellite network in KSP. How to combine several legends in one frame? Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. Hence, by launching a second satellite at t, this one is not only t days behind the first, but also t2 forward. Do not activate the antenna yet, or it will break off as your rocket builds up speed. 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. Archived post. Fortunately, getting into a stable orbit before you lose control doesnt demand any precision computing. Satellite exploding while in transfer orbit. Blind spots: Having a ring of satellites leaves blind spots on the surface (poles in case of equatorial ring). Can't remember if those or stock or not. 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).

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? By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Then pick the attitude command of your choice: press the SAS key, or click KILL to kill rotation, or click GRD+ to hold prograde (if you already have an active GRD+ command, you may have to click twice, then cancel the command labeled mode: off). It assumes you have not yet established a comsat network, so that the only connection of interest is a direct link between the . Interpreting non-statistically significant results: Do we have "no evidence" or "insufficient evidence" to reject the null?

Could a subterranean river or aquifer generate enough continuous momentum to power a waterwheel for the purpose of producing electricity? However, I was wondering, in what circumstances does your vessel bounce its signal off a relay satellite? 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. 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. Equatorial - This system has blind spots on the surface. Back before they made a real atmosphere I frequently sent up 5 satellites at a time, 4 radially and 1 on the front. (A spacecraft consisting of a pilot would not be affected.) Polar triangle orbit above 138km. Unfortunately, a path like that means you wont reach orbit until you are out of sight of Mission Control, and therefore out of contact. You just made my KSP save a whole lot cooler. Well actually kinf of yes. I basically do what @Geonovast posted. load your currently installed mods. Use RA-2 relays. As for any KSP probe, you will need a probe core, a battery, and (once you have the tech) solar panels. Use RA-15 relays. If you want probes at the poles, one solution is to just have another ring in a polar orbit. Please note that this page is incomplete, and requires the help of the community. 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!]. Which gives t = p/(8(p/k - 1)). Launch. 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. Note: Your post will require moderator approval before it will be visible. This tutorial covers the basics of launching a standalone satellite in RemoteTech. The other two antennas are optional for low enough orbits. If the satellites are high up the spots will be really small, but any terrain irregularities close to them will easily block the signal. All trademarks are property of their respective owners in the US and other countries. Equatorial triangle orbit above 700km. How can I control PNP and NPN transistors together from one pin? with relay antenna you build your network. Altitude depends on moon (500km for Laythe, 300km for Vall, 600km for Tylo, 65km for Bop and 44km for Pol). Send a couple small relay satellites with your probe. They are 100G, but noted, thanks. 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. You can do the same on upper levels using cubic octagonal struts to create extra nodes). 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.. All rights reserved. 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. Making three trips per body seems like a complete waste of time and resources when these satellites weight so little. 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). Doesn't save mass, but it does allow for SLIGHTLY longer satellites. 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. what's wrong here? With the addition of CommNet, you need a system of relays to connect back to the KSC. 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. What "benchmarks" means in "what are benchmarks for?". I am trying to deploy three relay satellite constellations. But I find it makes sense to put fewer sats on the top, so the fairing can taper around them. 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. 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. All trademarks are property of their respective owners in the US and other countries. 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. Use mod filters to select craft that; will work With selected mods. Have you checked if the two antennas are in range to communicate with each other? 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. What does 'They're at four. two satellites line up and both get occluded by Mun/Minmus, and the last one gets occluded by the other one. Effect of a "bad grade" in grad school applications. Any other Suggestions you may have! Has depleted uranium been considered for radiation shielding in crewed spacecraft beyond LEO? About 3000g orbiting outside Minmus. If an antenna can connect to the KSC (e.g. 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. 8 direct antennas therefore, will then double communication range for transmitting data. A Relay Satellite is a Probe orbiting a Celestial body that serves the function of creating a Relay Network. It looks more or less stock to me, although on close inspection it has some fiddly bits I can't quite identify. The orbital altitude must be greater than the radius of the body you are orbiting. 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. So the actual separation, in time, is actually t - t2 = t - t*p/k = t*(1 - p/k). Three panels is enough for near Kerbin, but you'll need more if you go farther out. What differentiates living as mere roommates from living in a marriage-like relationship? Let's ignore occlusion by Mun and Minmus for now and focus only on what it takes to not get blocked by Kerbin. Yes, that's how combine works. 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. 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. 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. That way, you wont have to worry about running out of power while halfway around Kerbin. is there such a thing as "right to be heard"? use the relays propulsion to circularise the orbit and match the target orbital period. Showing 1 - 13 of 13 comments How to build a satellite network around Kerbin which guarantees full coverage? If you have an antenna other than the DP-10, you will need to activate it in flight. 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. Could someone explain that as well? Deep space coverage may not be perfect. Method 1: Steep Ascent. Clear editor. 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. To establish this link, you require an antenna that has the range to reach it and no obstructions between them. It consists of three co-orbital satellites, 120 degrees apart. I use stock parts pretty rarely. 1 Relay Satelite in Stationary orbit in the Center of the light side of Minmus. Polar triangle orbit above 13km. However many Life Support mods will allow power drain from inactive crafts. Polar triangle orbit above 250km. Why are players required to record the moves in World Championship Classical games? Is there a weapon that has the heavy property and the finesse property (or could this be obtained)? Factor of division = 1 - 184 / 426 = 0.568.
