ASTRE - A Highly Performant Accelerometer for the Low Frequency Range of the Microgravity Environment

This paper describes the microaccelerometer ASTRE, developed as Laboratory Support Equipment of Columbus, to monitor the residual microgravity disturbance level in the very low frequency range. ASTRE will be integrated in the already flown Microgravity Measurement Assembly (MMA).

The paper recalls the microgravity environment which is required on-board Columbus and shortly describes expected discrepancies between the requirements and the predicted, more noisy, situation.
