Abstract : The report describes the digital program that has been developed to evaluate the orbit navigation and retrograde time prediction modes of the Gemini B computer software. The formulation of the program performs the same functions (in fortran computer language) as the orbit navigation (ONAV) and retrograde time prediction (RTP) modes. In addition, this program provides the capability to determine retrograde times to land at particular landing sites and can be used, in general, for mission planning purposes. (Author)
