6-axis Inertial Measurement Unit (3-axis accelerometer, 3-axis gyroscope)
I2C or UART communication interface (runtime configurable)
CubeSat Space Protocol support
The capability of performing extremely fine pointing maneuvers, high position accuracy, advanced attitude control including freeze mode, low vibration design and high energy efficiency make these Reaction Wheels ideal for low-GSD Earth observation CubeSat missions on 1U – 6U sized platforms.
Speed or torque control mode
Motor control optimized for low power usage
Fully automatic single-axis freeze mode
Wide range of self-diagnostic tools, including:
configurable software overcurrent protection
automated motor performance evaluation
in-orbit power consumption optimization
Improved radiation hardness features, including:
ECC non-volatile memory
radiation damage detection in all memory banks
Several degrees of redundancy within motor sensors and the possibility to run completely sensorless
Designed to reduce imbalance of the rotating parts
Low noise generation
Low-drift 3-axis gyroscope with built-in high-resolution temperature sensor
Runtime configurable I2C or UART communication interface with CSP support
5 or 8 V variants
Absolute maximum ratings
Stress above those listed as “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these conditions is not implied. Exposure to the absolute maximum rating conditions for extended periods may affect device reliability.
envelope dimensions were chosen so that the full three-axis reaction wheel
actuator system can fit comfortably within a 1U CubeSat.
Total momentum storage
1. BOL at maximum RPM, when using default amplitude model. Performance with customized and self-measured amplitude models may vary.
