Compute position and velocity of earth-orbiting satellites
Description
This Python package computes the position and velocity of an earth-orbiting
satellite, given the satellite’s TLE orbital elements from a source like
CelesTrak. It implements the most recent version of SGP4, and is regularly
run against the SGP4 test suite to make sure that its satellite position
predictions agree to within 0.1 mm with the predictions of the standard
distribution of the algorithm. This error is far less than the 1–3 km/day
by which satellites themselves deviate from the ideal orbits described in
TLE files.
