Basic Price € 2000

NanoAvionics Attitude Determination & Control System (ADCS) is based on the powerful ARM 32-bit Cortex™ M4 CPU enriched with radiation tolerant Ferromagnetic RAM and additional PWM outputs for driving external 3 axis magnetic actuators.

Users can develop their own ADCS algorithms based on provided standard board support package or purchase NanoAvionics ADCS software library which includes:

  • Unscented Kalman Filter attitude estimator
  • Orbit propagator
  • Full set of attitude control algorithms
