Abstract:

A boresight-calibration test is devised based upon the functional dependence of signal-strength measurements upon the antenna pointing relative to the direction to a ground-based transmitter. Algorithms are herein developed for the estimation of the antenna-boresight orientation relative to the spacecraft-attitude reference axes, the antenna beamwidths, and the boresight signal strength. Expressions for the expected error in the boresight parameter estimation are stated. Results of a computer simulation of the estimation process are included they agree with the theoretically expected performance. Formulas are included for the transformation of attitude and orbital parameters to determine the antenna-pointing direction. Author
