Permanent Link to Spectracom Introduces 16-Channel GPS Simulator for Receiver Testing
GSG-55 GNSS simulator
Spectracom, a global provider of time and frequency test and measurement solutions, will make available its new 16-channel GPS constellation simulator, the Pendulum GSG-55, in March. The GSG-55 is the latest in the Pendulum line of GPS receiver test instruments and part of its solution set for receiving, distributing, and validating GNSS systems.
With the enhanced signal generating capability of the GSG-55, it is possible to simulate Satellite-Based Augmentation Systems (SBAS), the company said. Navigation systems that use SBAS can improve the accuracy and reliability provided by the GPS satellite signals alone, enabling critical applications such as aircraft navigation, and surveying and mapping. SBAS simulation (support for Europe’s EGNOS and North America’s WAAS) is a new feature in the GSG-55. It is also able to generate white noise, making it possible to test receiver sensitivity under different signal-to-noise ratios.
“Many high-end GPS applications utilize 12-channel GPS receivers. Our new GSG-55 GPS constellation simulator can fully test those receivers with additional signals for more comprehensive testing in both development and production environments,” says Staffan Johansson, product manager at Spectracom.
The GSG-55 builds on the popular Pendulum GSG-54 eight-channel simulator including accurate testing of GPS timing receivers and portability through its compact and lightweight bench-top chassis. The GSG-55 also continues the Pendulum brand hallmark of ease-of-use. As such, the entire GSG family of GPS simulators has been improved based on customer feedbac, the company said.
