Knowledge of the mass properties of a small satellite is essential to understanding its flight dynamics and adjusting its attitude control loop. Space Electronics has developed the following suite of mass properties instruments:
- Our SE90168 series of instruments measure the center of gravity location of CubeSats and small satellites. These instruments come in several sizes for testing of payloads weighing from 500 grams (1 lb) to over 100 kg. Accuracy in the range of ± 1 mm is exactly what is needed for the small satellite community.
- Our XR series moment of inertia instruments measure moment of inertia. Three sizes are available to cover 1U CubeSats through 100 kg spacecraft. Accuracy is in the order of 0.25% of measured quantity, which is compatible with the generic accuracy of 1% for the industry.
- The FBD series are new spin balance instruments that measure product of inertia and perform dynamic balancing. Center of gravity can also be measured in a dynamic fashion on these instruments.
All of these instruments are intrinsically compatible with cleanroom requirements. They do not incorporate any hydraulic circuitry that could damage flight hardware.
