09/12/2011 - U-blox Selects Spirent Simulator to Evaluate Performance of its New GPS + Glonass Multi-GNSS Receiver Components

GPS + GLONASS Record & Playback and Multi-GNSS Simulator systems enable progressive testing approach

Sunnyvale, California and Thalwil, Switzerland – (September 12, 2011) – U-blox has selected Spirent's GSS6700 Multi-GNSS GPS + GLONASS simulator and Spirent's GSS6400 GPS + GLONASS Record & Playback test system to evaluate performance of its new GNSS receiver components.

"U-blox conducts rigorous testing on all new receiver designs," said Clemens Buergi, Vice President of Software at u-blox. "To make this process as efficient as possible, we use Spirent's multi-GNSS simulator remotely. Spirent's comprehensive remote command set enables us to complete the testing in the shortest possible time and in a repeatable way."

The GSS6700 multi-GNSS simulator is designed to be integrated into an automated test system or with the advanced Spirent SimGENTM graphical user interface. The GSS6400 Record & Playback system enables u-blox to capture complex real-world signal effects and then repeatedly replay the RF in the laboratory.

"Combining Spirent's record and playback system with the GNSS simulator enables u-blox to have a progressive and complete test approach," added John Pottle, Marketing Director at Spirent's Positioning unit. "With the traditional receiver characterization tests, u-blox is able to test for real-world signal effects and classic challenges of navigation systems. An example would be entering and leaving tunnels while simultaneously changing direction in mountainous and alpine driving scenarios."
