The effects of multipath cannot be ignored as they can compromise the performance and accuracy of any receiver design. Put simply, multipath refers to the phenomenon of radio frequency (RF) signals reaching the receiver via two or more routes. It is caused by the original signal being reflected or diffracted, typically by a building, geological feature or even water.

Record and playback systems (RPSs) such as the new Spirent GSS6400 can be used at many stages of the GNSS receiver design cycle and for many different tasks. However, one application that may not seem immediately obvious is in testing the ability of multi-GNSS receivers to work with both existing and future satellite systems. Clearly, the RPS cannot be used to playback signals from non-existent satellites. But used in conjunction with a simulator, the RPS can play a key role in...
