Aeroflex GPSG-1000 portable GPS and Galileo positional simulator

The GPSG-1000, said to be the first truly portable GPS and Galileo positional simulator, provides a low-cost 12-channel test set that creates three-dimensional simulations.

The device supports civil and military avionics field and bench maintenance technicians, production test technicians and system integrators with a modern simulator for L1, C/A code and L1C, L2C, L5 GPS modernisation signals, as well as new Galileo E1, E5, E6 services.

It can be configured with single, 6-, or 12-channel simulation. Typical tests include acquisition sensitivity, tracking sensitivity, time-to-first-fix for cold/warm/hot starts, time-to-second-fix, positional accuracy, RAIM failure tolerance and subsystem stimulation for 3D flight execution.

It uses modular technology for RF and baseband signal generation to produce accurate and repeatable test results and the system to be upgraded at low cost.

Features include: simulation of GPS L1C, L2C, L5 signals, supporting the modernisation of signals used by the latest designs of GPS receivers; simulation of Galileo E1, E5, E6 signals to support unencrypted services; SBAS, WAAS/EGNOS L1, L5 for automatic SBAS simulation; built-in GPS C/A code receiver for automatic GPS almanac download; waypoint navigation, a 3D navigation scheme that allows airport-to-airport flight-plan simulation; programmable satellite parameters allow specific tests to be conducted to determine receiver behaviour under degraded or invalid signal conditions; dynamic satellite signal simulation for real-world constellation signal conditions.
