All of our satellites follow the same physical laws that were first described by Johannes Kepler. A satellite's position at a specific time can be determined using seven distinct orbit characteristics named the "Keplerian orbit elements". These orbit elements define the satellite orbit's orientation with respect to the Earth, the satellite's last known position within its orbit, the shape of the satellite's orbit and the satellite's orbital speed.
