What is the correct speed in altitude? A spacecraft on this orbit will appear stationary when viewed from the surface. The following are instantaneous impulse calculations for equatorial low energy orbits, and therefore the real maneuvers will always be somewhat more than these values. The second one is at the apoapsis. To achieve this orbit, the craft must have a/an: When fine-tuning the position over KSC, remember that lower orbits move at higher velocities and higher orbits move at lower velocities. For direct launches, transfers from the lowest orbits will be more efficient because they require less delta-v to reach from the surface of Kerbin. For stationary orbits the periapsis maneuver should be executed when crossing the equatorial plane. For all your gaming related, space exploration needs. Hello everyone. you can really dial it in. About half way down it says. 5 hours, 59 minutes, and 9.4 seconds. Just get the right orbital period, don't try to get anything else perfect but that. Since the Kerbal Space Center is on the equator, the timing and trigonometry may be skipped. adding to this- make all your orbit adjustments with RCS instead of a rocket engine. The correct altitude is 2,863,334m. Press question mark to learn the rest of the keyboard shortcuts, http://wiki.kerbalspaceprogram.com/wiki/Kerbin, This is a Scott Manley video explaining how to do it. About 2863 km. You'll need to pause the game using Escape to get a precise value. As for the spacecraft, use a similar rocket to what you need to put a spacecraft orbiting the Mun. The only difference is you need to intentionally make your orbit temporarily bigger or smaller in order to move your craft above a specific location (if in the contract), New comments cannot be posted and votes cannot be cast, More posts from the KerbalSpaceProgram community, Continue browsing in r/KerbalSpaceProgram, The Kerbal Space Program subreddit. This places the spacecraft on a kerbisynchronous transfer orbit(KTO). My name is Ayden, I am a new person to this Subreddit. Resonant Orbit Calculator For Kerbal Space Program . Thank you for your time (Also. You can see on the right of the page there is a box with a bunch of info in it, you can see the same thing for the other planets on their page too. For your third question, there are some important things to remember about your ship: A source of power (solar panels) and a battery or two. As long as you get that orbital period precise your satellite will stay where it is even if your orbit isn't a perfect circle. It's much easier to get them phased and what not with the 1:3 period ratio going evenly. If their are any good youtube videos upon this may you please link them). The basic maneuver plan for reaching this orbit is to first achieve a low Kerbin orbit (LKO) and then perform two maneuvers to execute a Hohmann transfer. Higher LEOs may be preferable if the spacecraft is visiting a tug or space station and requires altitude above the atmosphere to execute a rendezvous. This places the spacecraft on a kerbisynchronous transfer orbit (KTO). Also his channel has some great starter tutorials. This can be useful when establishing a wireless connection between the craft and a structure on the surface, but it also makes observation of a certain spot on the surface easy. Since it is impossible to get all orbital values exact for a stationary orbit, satellites in stationary orbits form small analemmata. ... Place the bus into an eliptical orbit with a period of 2/3 geostationary Ap = 3,463,334.06m Pe = 1,822,703.04m Just before reaching Apoapsis detatch one satelite from the bus and when the sat reaches Apoapsis (3,463,334.06m) circularize its orbit. What is a nice spacecraft to use? you only need to calculate it if you are into that sort of stuff, otherwise just take it from the wiki. 2. The first one, called the periapsis maneuver, is raising the apoapsis to the required altitude for a synchronous orbit. Some celestial bodies don't allow for synchronous orbits because the altitude required to sync… But what really matters is the orbital period. How do I manage my speed? Kerbal Space Program. Surely you want a perfectly circular orbit? This means circularizing the orbit just below the 2 863 334.06 m mark will cause the craft to move "East" relative to Kerbin's surface, and circularizing just above with will move the craft "West" relative to the surface. The basic maneuver plan for reaching this orbit is to first achieve a low Kerbin orbit (LKO) and then perform two maneuvers to execute a Hohmann transfer. As powerful as you can manage. And as another note for OP, your height, inclination, circularization and anything else doesn't matter. 1 siderial day = 21,549.425 s (this is the period for geosync orbit, I don't think KSP worried about orbital precession) Using Keplers 3rd law, equitorial geostationary orbit r = 3,463,334 m or an altitude of 2,863.334 km circular with an orbital velocity of 1,009.81 m/s https://wiki.kerbalspaceprogram.com/index.php?title=KEO&oldid=77764. http://wiki.kerbalspaceprogram.com/wiki/Kerbin. About 2863 km. Español - Latinoamérica (Spanish - Latin America), http://wiki.kerbalspaceprogram.com/wiki/Kerbin#Orbits, http://steamcommunity.com/sharedfiles/filedetails/?id=575321399&fileuploadsuccess=1, https://en.wikipedia.org/wiki/Standard_gravitational_parameter, http://wiki.kerbalspaceprogram.com/wiki/Kerbin, https://en.wikipedia.org/wiki/Geostationary_orbit. These maneuver plans may also be useful for one who wishes to boost a large space station assembled in LKO to KEO (keep in mind that the craft may not have the thrust to make burns very efficient). Actually, I don't quite know myself, I copied these numbers from my most recient keostationary satellite contract. Aside from that, the rest is the same as any other rocket that can get things into space. To measure this in the stock game read the time to periapsis and time to apoapsis, find the difference, and double that. Why would the numbers be different? Do what you want, but you're going for extra credit here. You want to start off by getting to a 80km orbit before raising your apoapsis close to the correct altitude, then do a second burn at the apoapsis to circularize. By all means go geostationary, but the sheer amount of information/discussions/videos available doesn't reflect the necessity of it. 3. … http://kerbalspaceprogram.com, Press J to jump to the feed. All rights reserved. It's not much harder than a normal orbit, you need to get within marginal deviation just like other ones. I would recommend putting a small relay onto a oversized reusable booster. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. To measure this in the stock game read the time to periapsis and time to … What periapsis and apoapsis should be to ger 6 hours orbit? The wiki has lots of helpful info on this stuff too. Depending on the required orbit the second burn also includes nearly all of the plane change to reduce the equatorial inclination to zero. Kerbisynchronous Equatorial Orbit (or KEO for short) is the stationary orbit of the planet Kerbin, a very useful orbit for satellites. With a precision of one minute your satellite could end up anywhere in 180 Kerbin days, pretty lousy. To get an accurate orbit, set the thrust limiter on your engine to 0.5. It's a good challenge, it gives nice bragging rights, but it makes relay satellites a much more daunting task for beginners. 5 hours, 59 minutes, and 9.4 seconds. Calculate the resonant orbit needed for a carrier craft to inject craft it carries, like satellites, into equidistant positions of a shared circular orbit. With a precision of one second it will be several Kerbin years before there is any noticeable drift. A good relay antenna (NOT a direct antenna.) It's easier just to do 6 hours when you have 3 satellites for a relay network. Its 0° inclination and its eccentricity of 0 cause its ground track to be only a point: a satellite in this orbit has no motion relative to the body's surface. The second one is at the apoapsis. The first one, called the periapsis maneuver, is raising the apoapsis to the required altitude for a synchronous orbit. I have questions surrounding getting into Geostationary Orbit, 1. Stationary orbitsare a special kind of synchronous orbit. Depending on the required orbit the second burn also includes nearly all of the plane change to reduce the equatorial inclination to zero. Using mods, Kerbal Engineer gives a direct readout of orbital period. This page was last edited on 17 March 2017, at 18:31. All trademarks are property of their respective owners in the US and other countries. But what really matters is the orbital period. This is useful for setting up things like CommNet constellations. It's an old video (so his ship probably wont work exactly the same for you) but the actual tutorial part should still help. This is a Scott Manley video explaining how to do it. In theory those orbits also exists for other celestial bodies, but may be outside the sphere of influence.
