C# SGP4 Satellite Prediction Library. Load satellites from TLEs, convert between coordinate systems and reference frames, observe satellites from ground stations, and more.
sometime compute wont wrong,i position the code ` var before = maxElTime - deltaTime; if (clipToStartTime) // ensure before is clipped for max elevation search { before = start >...
I'm writing my own library for making life easier when working with orbits. Your readme indicates that your library can be used to convert between reference frames which is great...
I Implemented a very basic application using SGP.NET and I think I am getting incorrect range rate values. my little test app is tracking STARLINK-3962, and I can watch the...
Hello, I want to calculate the inclined azimuth, the angle of the place, the horizontal azimuth, the distance to the spacecraft. I downloaded this file, and I want to calculate...

The `clipToStartTime: false` parameter of `GroundStation.Observe` does not work, because the last term in the condition to walk back always evaluates to false: ``` if (!clipToStartTime && obs.Count > 0...
Under certain circumstances the elevation angle of a satellite gets stuck at some positive value, and `FindNextAboveToBelowCrossingPoint` finds the crossing only a few years in the future. This code reproduces...
