So there, the separation will be of p*t/k - t, but "forward". Now warp to your Ap and deploy the first relay. I figure I could add 20 days to the launch window (launch every 66 days). New comments cannot be posted and votes cannot be cast. 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. Check that the Delay (+ signal) display shows no delay. Polar triangle orbit above 250km. Fortunately, getting into a stable orbit before you lose control doesnt demand any precision computing. I tried launching one satellite every 46 days, but that didn't work. and our I basically do what @Geonovast posted. Ok cool, thanks for the help guys! Kerbal Space Program 1 KSP1 The Spacecraft Exchange Post Your Satellite Designs Post Your Satellite Designs By Wcmille, December 28, 2016 in KSP1 The Spacecraft Exchange Share Followers 1 Reply to this topic Start new topic 1 2 Next Page 1 of 2 Wcmille Members 116 312 About me: Rocketman Posted December 28, 2016 The orbital altitude must be greater than the radius of the body you are orbiting. :D.

By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. That factor goes negative, so you should launch back in time ? Equatorial triangle orbit above 138km. Although I am checking in version 1.5, so they might have new skins in later versions. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Use RA-2 relays. Archived post. I can't see why they wouldn't be able to. The large solar panels sort of look like Gigantor arrays maybe on pipes or actuators? The satellite is on the same side of the mun as the probe and has full signal from Kerbin. Does the 500-table limit still apply to the latest version of Cassandra? Polar triangle orbit above 700km. It only takes a minute to sign up. Use RA-2 relays. You then need to have (for 8 satellites) p/8 = t*(p/k - 1) with t the time between launches. There are two ways to avoid this, depending on your play style: following a steep launch path or using the flight computer. Relay Satellites are used to communicate with the Kerbal Space Center without the need for a direct connection to it. 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. Which is a pain so avoid this if at all possible. Which gives t = p/(8(p/k - 1)). How to build a satellite network around Kerbin which guarantees full coverage? A second equatorial triangle orbit at around 60,000km. 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. You probably. I also tend to make a network with RA-2 relays around a planet then a single larger relay in a highly elliptical polar orbit - so rovers or whatever talk to the nearest small relay, which bounces through the large relay back to Kerbin, rather than trying to make a network of RA-15 or RA100 relays in a single launch. and our You can post now and register later. 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. Interpreting non-statistically significant results: Do we have "no evidence" or "insufficient evidence" to reject the null? 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. This tutorial does not require any mods other than RemoteTech. Of course the trouble in KSP doesn't have Lagrange points (which is what Queqiao orbits). However, I have this other satellite which is out of contact with KSC, but in visual range of the relay satellite. A minor scale definition: am I missing something? 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 ! You can match that with 4 relays on one probe, or you can double it with 8. The HG-5 is a folding relay antenna, it's just not very strong. they have have antenna extended and are in range but their not bouncing back signals to get full conection. You can do the same on upper levels using cubic octagonal struts to create extra nodes). How do I view my network? If the satellites are high up the spots will be really small, but any terrain irregularities close to them will easily block the signal. Helpful Linkshttps://wiki.kerbalspaceprogram.com/wiki/Comm. a normal antenna can connect to a relay antenna or the KSC directly. how to plan pre-network missions around your limited line of sight to KSC. This page was last edited on 24 March 2023, at 18:10. 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). You may omit the third ring but deep space coverage in the outer system may be a bit spotty. You can get more details in this KSP forum post, which takes it from this research paper (paywall). A high orbit is easier to work with. Is there a weapon that has the heavy property and the finesse property (or could this be obtained)? Paste as plain text instead, > With proper resonance, you are in a mapping orbit and can complete grab/temp scans above x contacts without fuel burn. 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. Connect and share knowledge within a single location that is structured and easy to search. Once you get the really big satellite dishes, the signal will always bounce off that. 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. Polar orbit above 6,000km. Your satellite may just not be powerful enough to be better than Kerbin ground stations. Method 2: Flight Computer. Arqade is a question and answer site for passionate videogamers on all platforms. 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). load your currently installed mods. What does 'They're at four. Have you checked if the two antennas are in range to communicate with each other? 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. 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. 2 Satelites in matching orbits in opposite ends of eachother. https://wiki.kerbalspaceprogram.com/index.php?title=Relay_Satellite&oldid=104907. Thank you. So the actual separation, in time, is actually t - t2 = t - t*p/k = t*(1 - p/k). I am trying to deploy three relay satellite constellations. With the fact that each antenna has a limited range, this makes relay satellites a necessity for almost every interplanetary mission[citation needed]. But I find it makes sense to put fewer sats on the top, so the fairing can taper around them.

This satellite is out of control . How do I stop the Flickering on Mode 13h? Do not activate the antenna yet, or it will break off as your rocket builds up speed. Otherwise this scheme is resistant to placement errors. Polar triangle orbit above 60km. If not, is there a mod or config option to make folding antennas work as relays? I somehow missed interstage nodes since they were added ages ago, and haven't seen them in any videos that I can remember. 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. 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! The DP-10s main disadvantage is its 500 km range. Equatorial triangle orbit above 130km. 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. 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. Connect and share knowledge within a single location that is structured and easy to search. On what basis are pardoning decisions made by presidents or governors when exercising their pardoning power? So four 15G communication dishes on one sathave a range of 42 gm, which if I recall covers everything but Jool and Eeloo. Polar triangle orbit above 200km. You can also - if you don't want to use fairings and don't mind a draggy front-end on your rocket (hint: you should mind a draggy front-end on your rocket) you can also radially mount the satellites. Let's say p is the period of your target orbit and k the period of Kerbin orbit. Making three trips per body seems like a complete waste of time and resources when these satellites weight so little. Why are players required to record the moves in World Championship Classical games? Such a formation will provide coverage on all of Kerbin's surface and cannot get fully occluded by Mun/Minmus. Which ability is most related to insanity: Wisdom, Charisma, Constitution, or Intelligence? I thought the gold bit was a probe core, but it's the wrong shape. I'm using two HG-5 High Gain Antennae (class 3) on my relay and the Communotron 15 (class 2) on my lander. A Relay Satellite is a Probe orbiting a Celestial body that serves the function of creating a Relay Network. 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. For a start, I have placed a relay satellite in KEO. Thanks, found the answer. 8 direct antennas therefore, will then double communication range for transmitting data. 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. All trademarks are property of their respective owners in the US and other countries. 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. 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. What are the advantages of running a power tool on 240 V vs 120 V? 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. Suppose you want to put three relay satellites into circular polar orbit around Minmus. The other two antennas are optional for low enough orbits. It looks more or less stock to me, although on close inspection it has some fiddly bits I can't quite identify. Relay refers to the relay type antennae. Was Aristarchus the first to propose heliocentrism? I like to stack multiple satellites per level, as shown below (those are smaller sats of course, but the same concept applies). Since electricity isn't consumed when a vehicle isn't controlled by the player, electric charge storage and generation isn't required. If total energies differ across different software, how do I decide which software to use? Use RA-100 relays. Polar triangle orbit above 600km. 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. Did the Golden Gate Bridge 'flatten' under the weight of 300,000 people in 1987? 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. If you put the relays on opposite sides of a highly elliptical polar orbit, you should have very little loss of signal time. If you like, you can add a command to maintain attitude after the burn. 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. Making three trips per body seems like a complete waste of time and resources when these satellites weight so little. Let's ignore occlusion by Mun and Minmus for now and focus only on what it takes to not get blocked by Kerbin. This means tuning your launch trajectory so that you finish your final burn less than 280 km (27 longitude) downrange of KSC. 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. 2. Could someone explain that as well? As for any KSP probe, you will need a probe core, a battery, and (once you have the tech) solar panels. 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. Execute the burn as accurately as possible. So how do you launch and control the very satellites that are supposed to help you do the controlling? 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. 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. Or you can just leave it where it is, happily beeping away. 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. If you have solar panels, deploy them as soon as you are out of the atmosphere, even if its a night launch. All trademarks are property of their respective owners in the US and other countries. Cookie Notice This tutorial covers the basics of launching a standalone satellite in RemoteTech. Otherwise you risk launching nothing but a future fireworks display for the citizens on the far side of Kerbin. However, I was wondering, in what circumstances does your vessel bounce its signal off a relay satellite? 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. Equatorial triangle orbit above 250km. Every time it passes over KSC, you can send or schedule more commands. What differentiates living as mere roommates from living in a marriage-like relationship? I thought the gold bit was a probe core, but it's the wrong shape. Use RA-2 relays. 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. What antenna are you using on the relay? 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). 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. Type a delay that corresponds to just after the orbit insertion is finished (any attitude commands sent during the burn will be ignored). Since Kerbin is faster than, say, Jool, the second satellite you launch will end up forward the first anyway. If you want probes at the poles, one solution is to just have another ring in a polar orbit. How can I control PNP and NPN transistors together from one pin? I think I have a pic around here somewhere I'll try to dig it up and update this post with it. It only takes a minute to sign up. It's not them. 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. With a 15G antenna, you get much better deep space coverage. Some trial and error may be necessary if youre used to shallower launches, but the traditional 45 ascent path should work. Please consider starting a new thread rather than reviving this one. Of course the trouble in KSP doesn't have Lagrange points (which is what Queqiao . Polar triangle orbit above 138km. What "benchmarks" means in "what are benchmarks for?". 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. 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). I don't have the buttons to the right of the clock that are in the OP's screenshot. KSC only boasts 250G. Why do men's bikes have high bars where you can hit your testicles while women's bikes have the bar much lower? Learn more about Stack Overflow the company, and our products.

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. 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. That gives an orbital period of roughly 184 days. Deep space coverage may not be perfect. 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. Satellite exploding while in transfer orbit. Upload or insert images from URL. Weaker signal (network paths shown) A Screenshot of Kerbal Space Program. Use RA-2 relays. Unfortunately, a path like that means you wont reach orbit until you are out of sight of Mission Control, and therefore out of contact. ], Maintaining control during probe atmospheric landing with RemoteTech. 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. 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. 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? Clear editor. Actually I never have figured out a way to tell exactly how many Gs are had by a relay sat with multiple antennas. If you have an account, sign in now to post with your account. Didn't know about having to enable the option. What risks are you taking when "signing in with Google". Anyway, worth mentioning is that this is a very inefficient way to do a relay satellite. 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. 2023 Take-Two Interactive Software, Inc. The best answers are voted up and rise to the top, Not the answer you're looking for? Any other Suggestions you may have! This page was last edited on 19 July 2020, at 20:55. The End. Hello- I thought in this play-through it would be fun to set up my own relay satellite network. 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 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). If you have the Comms DTS-M1, right-click on it while on the launchpad, then click the button marked No Target. This satellite is in visual range of KSC. I got the same answer from the KSP fora, but with minimal explanation of the underlying math. Mun/Minmus occlusion: All the satellites can get occluded when either. Thats it! Make sure you take care of all maneuvers before you pass out of contact. If an antenna can connect to the KSC (e.g. Polar triangle orbit above 13km. Use RA-2 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. With update 1.2, you need to make sure that probes always have a communication link to Kerbin. 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. But adding it 40 degrees away is OK and will prevent occlusion from Mun/Minmus.). Rather than opening instantly, the solar panels will appear in the queue, scheduled to open after the delay. If you don't have the extra ground stations, then you can only talk to KSC, which is facing away from your ship 50% of the time. Use mod filters to select craft that; will work With selected mods. A set of 24 evenly spaced satellites at around 50,000,000km. SpanishInquisitor27 4 yr. ago Left: A comlink-friendly ascent path. For an inner orbit (p Is Michael Palin Still Married,
