Spirent Communications will unveil its enhanced GSS9000 Series GNSS constellation simulator at ION GNSS+ 2019 in Miami, which will take place Sept. 16–20. It joins Spirent’s already impressive range of test solutions on display at the world’s largest showcase of GNSS technology, products and services.
“The industry is at a very important point,” said Spirent Marketing Director Steve Hickling. “With the volume of GNSS signals growing, more multi-constellation receivers being developed every day, and the need for greater precision increasing all the time, it’s vital that testing solutions are able to stay ahead of this reality. This is why we’re excited to demonstrate the enhanced GSS9000 Series at ION.”
The GSS9000 Series constellation simulator has been improved with enriched features and enhanced capabilities combined with an increased channel capacity. Most importantly, this greater flexibility, coherence, fidelity, performance, accuracy and reliability is maintained under all test conditions.
At ION, Spirent (booth E) will also be showing its GSS6450 — the highly portable 16-bit RF record and playback system — and the GSS7000 series multi-frequency, multi-GNSS RF simulation solution. Visitors can also learn more about Spirent’s realistic multipath and obscuration simulation tool, the new Sim3D.
Spirent’s expertise will also be demonstrated during three ION GNSS+ speaking panels:
“Simulating Realistic Ionospheric Scintillation of GPS Signals for Robust PNT Testing,” presented by Spirent’s Talini Pinto Jayawardena
“Development of Array Receivers with Anti-Jamming and Anti-Spoofing Capabilities with Help of Multi-Antenna GNSS Signal Simulators,” presented by German Aerospace Center’s Andriy Konovaltsev
“Robust and Resilient PNT in Autonomous systems — the Need for the Development and Testing of Both Offensive and Defensive Technology,” reserve paper to be presented by Spirent CAV software engineer Felix Krefft
