dsgp4.sgp4

dsgp4.sgp4(satellite, tsince)

This function represents the SGP4 propagator. Having created the TLE object, and initialized the propagator (using dsgp4.sgp4.sgp4init), one can use this method to propagate the TLE at future times. The method returns the satellite position and velocity in km and km/s, respectively, after tsince minutes.

Parameters:

satellite (dsgp4.tle.TLE): a TLE object. tsince (torch.tensor): a torch.tensor of times since the TLE epoch in minutes.

Returns:

(torch.tensor): a tensor of len(tsince)x2x3 representing the satellite position and velocity in km and km/s, respectively.
