system.
- Software package to control the 6-DOF propulsion system.
- Support
1 set
○ Latest Delivery Date: February 21st, 2020
The contractor for the Electrical Simulator shall be capable of providing Flight Models of the 6-
DOF propulsion system under a separate contract to be placed next year.
○ Requirements
The following requirements shal be applicable for the
6-DOF propulsion system and the
Electrical Simulator shal be aligned with these requirements where applicable:
The propulsion system shal be capable of providing 6-DOF motion of a 6U
nanosatellite (this means translation along and rotation around all 3axis)
Size: Less than 2U (20x10x10cm) of total size
Mass: Less than 2kg
Mechanical Interface: The propulsion system must be suitable for standard 6U
cubesat shape (Redesign of the structure should be avoided)
Electrical interface:
-
Communication shall be possible over these data buses: CAN, I2C, UART
Performance:
-
Max thrust: 20mN for each axis
-
Total Delta-V: around 16m/s (assuming a 10kg nanosatellite)
-
Capability to measure delivered impulse by each thruster in near real time
Quality & reliability:
-
The propulsion system shal have flight heritage or equivalent qualification tests
performed
-
Capability of meeting radiation requirements equivalent to 5 years in LEO (20
krad)
-
Propulsion system design shall be compliant to the tailored ECSS standards for
IOD cubesat projects
-
All electrical components shall be de-rated according to ECSS standards
-
The propulsion system shall have redundant sensors for all critical components
The Electrical Simulator shall mimic the FM module in a representative way, including
communication, thruster performance, thruster diagnostics, timing and sequencing of
commands, monitoring of propellant tanks and feed system. More specifically, the Electrical
Simulator shal have a fully flight representative interface and control electronics board,
including identical connectors, so that the Electrical Simulator can replace the FM module in a
satellite simulator or a flat-sat system.
