Spirent Communications today announced the launch of its new GSS6300M Multi-GNSS simulator designed for integration, verification, and production testing where a quick and accurate functional test is needed. The platform supports simulation of signals from individual or combined GPS/SBAS, GLONASS, and Galileo constellations, with eight satellites per constellation. The GSS6300M supports two modes of operation — integrated into an Automated Test Equipment (ATE) environment or using Spirent’s SimCHAN software. For automated operation, the GSS6300M can be synchronized with other equipment and controlled remotely over Ethernet, IEEE-488 (GPIB), or RS232 interfaces. The SimCHAN software interface supplied with the GSS6300M enables the user to create unlimited scenarios and specify parameters such as user position, date, and time. Both modes support precise user control over power level and atmospheric effect selection. “The GSS6300M is designed for customers who want an affordable, easy-to-use multi-GNSS test system with the quality, reliability and support that is expected from Spirent,” said Rahul Gupta, product manager with Spirent’s Positioning Technology business. “The GSS6300M enables testing of fundamental receiver functionality including time to first fix, sensitivity, and accuracy.” The GSS6300M is now available for order. A field upgrade pack is available for existing Spirent GSS6300 customers who want to leverage the multi-channel capabilities of the GSS6300M.
