The GNSS simulation provides feedback for GPS Glonass and Galileo satellites simultaneously

GNSS Simulator Tests Up to 24 Satellites in Realtime

July 16, 2013

As part of a vector signal generator, a new GNSS simulator promises to allow testing for specific developing problems such as obstruction from buildings and tunnels and even the metal bodies of vehicles.

A new global navigation satellite system (GNSS) simulator aims to create real-world scenarios for automotive and wireless developers by creating scenarios such as obscuration from buildings, tunnels, and bridges and multipath propagation. Running through Rohde & Schwarz’s SMBV100A vector signal generator, the simulator tests GNSS receivers in a variety of stationary and mobile scenarios.

The GNSS simulator uses up to 24 satellites to generate signals in realtime for GPS with civilian C/A code and military P code, as well as for Glonass and Galileo constellations for smartphone developers. If the receiver is located inside a vehicle, testing takes into account the obscuring effect of the vehicle’s metal body and the subsequent additional antenna patterns. Aerospace and defense applications can be simulated at a rotation rate up to 400 Hz.
