Permanent Link to Orolia introduces new GNSS testing and simulation portfolio
Orolia introduced its new GPS/GNSS testing and simulation portfolio, including the new GSG-8 advanced simulator, at ION GNSS+ 2019 in Miami.
The new portfolio offers a comprehensive array of GNSS validation technology, as well as signal and PNT data protection through jamming/spoofing detection, suppression and countermeasure solutions.
The capabilities are built on Orolia’s legacy of resilient PNT solutions, together with two key acquisitions completed this year: Skydel Solutions and Talen-X. These companies were selected based on their demonstrated GNSS testing and simulation experience.
GSG-8, the latest advanced simulator from Orolia, was also introduced to the global GNSS community this week at ION GNSS+. This software-defined simulation solution offers ultra-high performance and unmatched flexibility in an easy-to-use format. GSG-8 was developed to deliver the highest standard of GNSS signal testing and sensor simulation performance, in an upgradable and scalable platform.
“With its scientific precision and advanced simulation capabilities, GSG-8 is revolutionizing the GNSS simulation industry with Orolia’s robust 1000Hz Skydel software engine and COTS software-defined radios,” said Stephane Hamel, director of testing and simulation at Orolia. “GSG-8 is designed for customers that require complex capabilities to validate product and program performance in harsh, high risk environments where failure is not an option- such as government agencies, space programs and specialized commercial programs.”
It can be programmed to simulate operations with multiple GNSS constellations and to incorporate the use of encrypted or proprietary signals. GSG-8 can also be configured for Wavefront and Anechoic chamber simulation protocols to test anti-jam antennas and complete systems, to serve the most challenging program requirements.
