Track earth satellite TLE orbits using up-to-date 2010 version of sgp4

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 of the predictions of the standard C++ implementation 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.

The C++ function names have been retained, since users may already be familiar with this library in other languages
