Abstract
Two techniques to sequential acquisition of global navigation satellite system (GNSS) signals are investigated, one treats the GNSS signal acquisition problem as multiple hypothesis testing problem and the other treats the same problem as binary hypothesis testing problem. Both techniques do not rely on the generalized likelihood ratio test (GLRT), rather on a posteriori probabilities as test statistic. Mechanism of propagating the probabilities when a new measurement arrives, differes in both cases. Simulation results have been presented comparing the detection performance of both schemes in different scenarios.
