Abstract : We have applied a system modelling approach to the problem of projecting the performance of an enhanced NAVSPASUR system. We have modelled the performance characteristics of the current system as well as the out-of-plane station (OOPS) and enhanced signal processing options described in the NAVSPASUR System Development Plan, Phase II. The objective of this modelling process was to evaluate the ability of NAVSPASUR to provide satellite position and velocity measurements to the accuracy required for first pass orbit determination (FPOD). The FPOD position and velocity requirements have been taken to be 1.67 km and 2 km/min, respectively, as specified in the NAVSPASUR System Development Plan, Phase I.
