Platform Compatibility
Design Drivers
Cubesat & Small Sat Constraints
Mass and volume budgets are tight. Propellant handling restrictions apply in integration facilities. Mission operators require predictable, characterised impulse bits for ADCS algorithms.
- 6U–16U cubesat volume envelopes
- No toxic propellant authorisation in many facilities
- Digital valve control from ADCS board
- Thermal compatibility with CubeSat Standard
CG-Series Solution
