Abstract
Measuring instruments, such as ultra-sensitive accelerometers, are attached to a support inlcuding three pairs of electrodynamic or piezoelectric actuators. Each actuator pair is associated with one respective common axis of a reference trirectangular system. An electronic speed and phase slaver chains the actuators to induce translational and rotational accelerations in the support. Electrical signals delivered from the instruments to be calibrated are analyzed by synchronous demodulations and processed to determine sensitivity, orientation and position of the instruments in relation to the reference axes. The instrument support can be carried on-board a satellite.
