GSG-7 Image

The GSG-7 from Safran is a GNSS Simulator with advanced simulation capabilities available in a compact form factor at a competitive price. It features an internal RF combiner and provides high-end performance with a 1000 Hz simulation iteration rate, high dynamics, real-time synchronization, Hardware-in-the-Loop (HIL) integration, and simulation of all-in-view satellite signals. This simulator is powered by Orolia’s industry-leading Skydel simulation engine and can be programmed to simulate operations with all current/future GNSS signals. It is ideal for development and integration projects that require high performance, all-in-view satellite signals, and an increased number of GNSS constellations.

The GSG-7 leverages the powerful Skydel software and commercial-off-the-shelf (COTS) hardware to accommodate almost any configuration to conduct system testing and simulation. Skydel’s architecture enables future-proofing of this simulator allowing new and incoming signals and updates to be implemented through software updates. The unique and modern architecture of the Skydel simulation engine provides an extensive application program interface (API) to configure and control all aspects of the simulator. Moreover, all human and machine interactions with the simulator can be recorded and exported as executable python scripts.

This simulator can also incorporate proprietary signals with a comprehensive SDK, which allows the generation of even the most sensitive signals. It can be used alone or in combination with other Skydel-powered simulators like the GSG-8 or Wavefront and Anechoic test solutions. The GSG-7 is available in an enclosure that measures 48 x 41 x 9 cm with HDMI/USB/Ethernet ports and various RF connectors. It requires an AC supply from 100 to 240 V and consumes 400 W of power.
