Abstract:	A purely statistical wideband land mobile channel model suitable for Global Navigation Satellite Systems (GNSS) software and hardware simulations is proposed. The model considers the specific requirements of GNSS (in comparison with channel models for telecommunications) but also the limitations of the hardware and software simulation platforms. The channel incorporates a tap delay line model combining well-known statistical approaches with other empirical/experimental observations from physical-statistical studies. This solution allows flexibility in the evaluation of multipath and shadowing in GNSS land mobile receivers. The model characteristics are described and finally pseudorange tracking error results from software (using SNACS software tool) and hardware simulations (using Spirent Radio Frequency Constellation Simulator) and a number of channel test cases are presented.
