Aebestach Posted July 16, 2023 Share Posted July 16, 2023 (edited) Sun Synchronous Orbit Calculator SSO Calculator Online Abstract In the Kerbal Space Program, planets are regular spheres. After adding Principia, planets like Kerbin do not have sun-synchronous orbits. And this tool can generate configuration file of Principia, so as to add the second-order spherical harmonic coefficient j2 to the stock planet to help players successfully enter the sun-synchronous orbit of the stock planet. At the same time, this tool also supports the calculation of relevant parameters of the sun-synchronous orbit in the RealSolarSystem environment. Dependencies The newly generated xx_xx_GravityModels.cfg file requires support from Kopernicus. If you want to enter a sun-synchronous orbit, you must have the support of Principia. You must download Planet Stock Essentials.cfg from Spacedock or GitHub into GameData to use it, especially for players who use Planet Stock. Chinese Version Tutorial (obsolete) Credits @SirMortimer Kopernicus configuration file. @Nazfib Code help for calculating sun-synchronous orbit inclination and other formulas. @Charon_S丶 KSP players have provided help for adding second-order spherical harmonic coefficient terms. @PrincipiaTeam Provide file support for planetary data in the RSS environment. @tinygrox Thank you for his suggestions on language and unit options. NewBing The planetary rotation period under RSS is provided. Edited August 20 by Aebestach Modify image link Quote Link to comment Share on other sites More sharing options...
Max_Xu Posted September 15, 2023 Share Posted September 15, 2023 thanks for your work! this is exactly what I need. Quote Link to comment Share on other sites More sharing options...
SpaceFace545 Posted August 2 Share Posted August 2 Any chance we could get this for KSRSS and 2.5x systems? Quote Link to comment Share on other sites More sharing options...

It is not difficult to adapt them, but it takes a little time. https://github.com/Aebestach/Principia-SSOCalculator.github.io/blob/65ddff7fb9a858d98c6d21d53b6d8e2b613a34f8/addEventListener.js#L1 But I think they should be the same as StockBodies, requiring users to customize j2 parameters. I am currently working on rewriting my WDSP. After everything is finished, I may start working on adapting SSO Calculator to ksrss.

Aebestach Posted August 19 Author Share Posted August 19 @SpaceFace545 Hi, I am preparing data for KSRSS and 2.5x recently. I wrote a C# program and generated an assembly. Could you run it in KSRSS and 2.5x environments respectively, and then send me their KSP.log? You just need to enter KSC and wait for a while before closing the game. https://drive.google.com/file/d/1IeDHWMTwANM0hICXYm0cUVNTgQKvljUW/view?usp=sharing Quote Link to comment Share on other sites More sharing options...
