OPTIMUM SIX PARAMETER ESTIMATION PROCESS FOR NAVIGATION SATELLITE (SRN-9) DATA

An optimum six parameter estimation process employing a weighted quadratic performance index is formulated and programmed for the reduction of data from the integrated doppler navigation satellite system (SRN-9). The six parameters of the state are taken as errors in the initial estimates of receiver latitude, longitude, frequency, velocity north, velocity east, and geoidal height. For weighting purposes, a priori estimates of both the measurement covariance and the state covariance are required. In return, the program produces both the "best estimate" of the state and, of equal importance, the expected errors of this determination in the form of the output state error covariance. A method of adjusting this covariance to reflect the achieved value of the performance index is presented.
