Spectracom Simulators Add Channels, Signals

Spectracom announces its ability to simulate up to 64 RF channels in four frequency bands for testing the integration of most advanced GNSS receivers.

The GSG series of GNSS simulators are designed to offer as much capability as needed by developers, integrators, and manufacturers of applications for global satellite navigation. “We understand the needs for simulating GPS and GNSS signals varies as much as the applications themselves,” said Spectracom CTO John Fischer. “Now the diversity of GNSS signals enables a new generation of receivers requiring a new set of test tools. We designed our simulators to grow along with the GNSS eco-system while maintaining the affordability and ease-of-use that has been our hallmark.”

Spectracom offers two fully configurable and upgradeable platforms. For common single frequency applications, the GSG-5 series simulates up to 16 GPS satellites in the L1 band. Users can start with a single-channel RF generator and upgrade their unit in the field when their needs change. For more advanced applications, the GSG-6 series offers up to 64 channels in four different frequency bands simultaneously. Current firmware generates GPS and GLONASS satellites in L1, L2, L2C, and L5. Customers will receive firmware updates when they need to simulate Galileo and Beidou satellites in the E1/B1, E5/B2, E6/B3 bands.

In addition to generating satellite signals, these GPS and GNSS simulators include other advanced capability in every unit such as simulating satellite-based augmentation systems (SBAS), dynamic motion characteristics (trajectories), multipath, white noise, and interference. Tests can be performed anywhere, anytime, from the convenience of the test bench, Spectracom said.

“Comprehensive testing and validation of high-reliability positioning, navigation and timing applications has been a natural extension of our rich heritage in delivering precision time and frequency products and systems,” said Spectracom CEO Lisa Withers. “As we continue to expand our GNSS signal management offerings, we are excited to introduce synchronization, simulation and test  solutions that are geared to be readily adaptable to our customers’ unique applications.”
