Antenna rotor

Communication with satellites demands accurate pointing with the antennas.

2D test bench

Cubesats is normal 900 km above surface and move with 8 km/sec. In the upcomming

 This gives only a few minutes for communication when it passed from horizon to horizon.

Project short

• mechanics
  • select antenna system (yagii or dish on roof)
  • do mechanical/dynamic modelling
• electronics
  • sensor and actuator interfaces
  • robustness considerations
  • safety
• control
  • antenna control :-)
  • including dynamic and sensor/actuator modeling
• communication
  • development of a safe reliable protocol from host to antenna controller
  • orbit update system based on retrieve of data from http://celestrak.com/
  • coordination of several antenna systems
  • interface/handles to interface with radio systems (no HF technique :-)
