One of the current limitations to evaluate the impact of a realistic multipath environment over a GNSS receiver is the high number of multipath rays that are needed to model the channel in a HW RF constellation simulator. That makes necessary the application of reduction techniques to decrease the number of channels per satellite to be simulated. The initial evaluation of two reduction techniques based on the solution of optimization problems is presented for an urban vehicle scenario, focusing the study on the evaluation of the multipath effect over code pseudorange measurements.
