spacecraft tracking

Spacecraft tracking involves monitoring the position and movement of a spacecraft in space. This is achieved using ground-based antennas that send radio signals to the spacecraft and receive its responses. By measuring the time it takes for signals to travel, and analyzing their frequency changes (Doppler shift), we can determine the spacecraft’s location, speed, and trajectory. This information is vital for navigation, mission planning, and ensuring the spacecraft remains on its correct path. Tracking combines radio science, satellite data, and orbital calculations to keep space missions precise and safe.
