The report describes the orbit determination programs and data processing programs developed by TRW Systems for the Lincoln Laboratory Millstone Hill radar. These programs provide the SDS 9300 computer associated with the radar with the following capabilities satellite orbit prediction, antenna steering, data and editing averaging, and differential correction of the orbit elements. The programs that support the radar during a tracking operation are fully automatic, under the control of the radar hardware and the operators console. They perform sufficiently fast to permit their use during a radar tracking pass and, thereby, provide real time orbit determination capabilities in supporting the tracker. This facility is accomplished by partitioning the orbit determination functions into those which can be performed before the pass, after the pass, and doing only the absolute minimum processing during the pass. The capabilities in the real time programs MHESPOD have also been provided in a stand-alone support program for nonreal time use NRTPOD.
