GNSS Simulator Tests Up to 24 Satellites in Realtime

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.

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

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.
