Abstract : TRACE is a multiple-purpose satellite orbitdetermination program for the IBM 7090 computer. Its applications include: (1) prediction - the generation of a satellite trajectory and associated ground trace and station sighting data; (2) orbit determination - estimation of trajectory parameters, station locations, and observational biases, so as to best fit a set of observations; and (3) error analysis - estimation of the potential accuracy attainable by a tracking system, given the station locations, the data types, rates and quality, the uncertainties in the model parameters, and the specifications of the nominal orbit. The report contains the objectives of the program, some theoretical foundations, the equations and methods employed, the structure of the program, and complete instructions for its use.
