Description
It is generally recognized that proper calibration is a necessary ingredient in the effective utilization of a tracking system. This paper presents a method of calibrating space object tracking systems under dynamic conditions which closely approximate those of the operational environment. Briefly, this calibration scheme involves the tracking of a reference satellite whose position in space is very accurately known as a function of time. By means of a set of digital computer programs, the unknown error model coefficients of the tracking system are extracted by operating upon the differences between the track observations and the reference satellite positions .
This calibration method has been successfully applied to a number of systems, particularly the AN/FPS-49 trackers of the BMEWS and Spacetrack systems of the USAF Air Defense Command. The essential results of this calibration activity are presented to illustrate the application of the technique.
