Precise Orbit Determination

Precise Orbit Determination (POD) is the process of accurately tracking the position and velocity of a satellite in orbit using GNSS. Learn more about our Earth information data here

Tracking satellite orbits solely from the ground using fixed ground antennas carries a margin of error, but using GNSS systems in space allows for real-time autonomous determination of a satellite’s position. This is especially important for remote sensing satellites as they gather data about specific patterns and events on Earth.
