First nanosatellite for ESA/ESOC

This project is carried out under the ESA GSTP programme

The "OPS-SAT nanosatellite" provides a safe and reconfigurable "hardware/software laboratory", flying in a low-earth orbit, available for authorised experimenters to demonstrate innovative new mission operations concepts.

OPSSAT with solar panels OPS-SAT Bus

The OPS-SAT bus provides the necessary fail-safe infrastructure to operate the payload. It comprises the following subsystems:

  • On-Board Computer (OBC)
  • Coarse Attitude Determination and Control System (ADCS)
  • Electical Power System (EPS), including solar panels and batteries
  • UHF Transceiver for basic low-data rate telemetry and telecommanding
