PROJECT 861 ORBIT PROGRAMS

Abstract

In the Project 861 system, a radar will make observations on the Project 861 orbit and record these on magnetic tape (or, alternatively, on teletype tape). This tape will be processed by a point-selection program which filters the dataAND REDUCES THE AMOUNT TO A MANAGEABLE SIZE. A coordinate-conversion program then maps the data from the radar coordinate system to the geocentric equatorial system. An orbit-fitting program fits to the transformed data a Keplerian orbit. The orbit parameters are then used by a parameter-prediction program for ultimate input to the pointing program which supplies paper tapes with driving information for the Project 861 antennas. The coordinate-conversion program and the orbitfitting program are described. (Author)
