software for satellite orbit determination

Software for satellite orbit determination uses mathematical models and observed data—such as from ground stations or onboard sensors—to accurately calculate a satellite's position and velocity in space. It processes signals like GPS, radar, or optical measurements to estimate the satellite’s orbit, accounting for factors like Earth's gravity, atmospheric drag, and Sun’s radiation. This software ensures precise tracking, which is essential for navigation, scientific missions, and satellite operations, by continually updating the satellite’s location in near real-time to maintain correct orbits and mission objectives.
