Abstract

The results of an analysis of the precision pointing and tracking accuracy possible between satellite-borne optical linking systems using measured platform disturbance data are discussed. Measured vibration data from the Landsat satellite were used to generate the power spectral density parameter needed to model the baseframe noise environments for the two-satellite system. Three control subsystem configurations were evaluated: gyro-stabilized, mass-stabilized, and complementary filter. The sources of error included in the analysis were sensor noise from the optical detector, host satellite baseframe vibrational noise, and frictional and bearing noise. The results of the study indicate that a 1 µrad rms pointing and tracking accuracy may be achieved with either the gyro-stabilized or the complementary filter approach.
