Abstract

Abstract

The quality of Signal-In-Space (SIS) for Global Navigation Satellite System (GNSS) is directly linked to users Positioning, Velocity and Timing (PVT) service. Limited to the insensitivity of authorized signals, the pseudo codes can not be obtained, so it is difficult to assess the authorized signal quality. This paper mainly focus on analyzing the Coherent Adaptive Subcarrier Modulation (CASM) signal on L1 frequency points for GPS BIIF-5 satellite and the code sequences of P(Y) and M signal are resumed by using matched filtering technology. The power distribution of each signal component can be solved through the maximum likelihood estimation theory combined with the signal characteristics. This paper laies special stress on quantitatively analyzing the correlation performance on P(Y) and M signals, including correlation curve, correlation loss and S-curve biases. Based on this complete authorized signals quality assessment method for GPS L1, the research productions can be reference to other satellite navigation systems authorized signals.
