Ground Station

The Earth Station is designed to communicate with satellites in low Earth orbit (LEO) and performs many important functions:

  • Receiving and Sending Data: Receives data from and sends data to LEO satellites. This data includes satellite health data monitoring, missions and imagery captured.
  • Monitoring and Control: It monitors the position and orbit of satellites, checks the health status of satellites and takes corrective maneuvers if necessary. This ensures that satellites remain in the correct orbit and successfully fulfill their missions.
  • Telemetry and Command: Telemetry and command operations monitor the status of satellite systems and send commands when necessary. This function is critical for the operation and security of satellites.
  • Data Processing and Storage: Processes and stores raw data received from satellites. The processed data can be transmitted to local or remote data centers for later analysis and use in various applications.
  • Timing and Synchronization: It ensures that satellites are synchronized to receive images from specific points on Earth. This feature is critical for observation satellites.
  • Recovery and Reconfiguration: Manages recovery operations in the event of a lost connection to the satellite or in the event of a failure, and performs reconfiguration operations to restore the satellite's functionality when necessary.

The ground station is vital to the success of satellite operations and is used for the operation of satellites developed at the Institute.
