Orbit Explorer: uses and methods
Explore satellite orbits and ground projections starting from six root numbers or TLE.
Applicable scope and calculation boundary
six-radius mode is a two-body elliptical orbit; the TLE mode uses SGP4. The ground trajectory is rotated using GMST without adding polar motion.
model and reference method
Kepler equation; Vallado SGP4.
model version: 1.0.0. The results are used for scientific research, exploration and teaching, please interpret according to the model conditions.
