Scientific paper

Attention is given to the features and experimental results of an all-digital data flow simulation of the Gravity Probe-B gyro and teslescope that demonstrates the Kalman filter data reduction process for detection of relativistic drifts. The simulation is noted to demonstrate successful optimal estimation of relativity effects in the presence of the expected measurement noise, consistent with six- and twelve-month simulation runs. The Kalman filter encompasses a low-pass analog presampling filter, the estimation and feedback of a sinusoidal dither signal, and a SQUID noise-shaping filter.
