Abstract : The Photogrammetric and Tracking Network Analysis Program (FOTONAP) is a rigorous general purpose long arc multi-satellite orbit determination and parameter estimation program. It is capable of simultaneously processing photogrammetric observations collected by an orbiting camera along with observations from conventional ground based and satellite to satellite tracking systems. In addition to the recovery of satellite orbits the program provides estimates for the relative location of ground points (observed by the orbiting camera), various camera error model parameters, the location of ground based tracking systems, plus an ensemble of error model parameters associated with the various tracking instruments. The entire program is written in FORTRAN and is operational under the SCOPE 3.3/3.4 system on the CDC 6600 computer system. (Author)
