GNSS Constellation Simulator Flexibility Adds Channels, Signals, and Frequencies

ROCHESTER, NY USA (March 4, 2013) — Spectracom, a business of the Orolia Group (NYSE Alternext Paris – FR0010501015 – ALORO) and the leading provider of powerful, easy-to-use and affordable test solutions for GPSGlobal Positioning System is a navigation satellite system. See also and GNSSGlobal navigation satellite system (GNSS): A general term describing any satellite constellation that provides positioning, navigation, and timing (PNT) services on a global or regional basis. See also devices and systems, today announced its ability to simulate up to 64 RF channels in 4 frequency bands for testing the integration of most advanced GNSS receivers.

The GSGA GNSS Signal Generator is a device that is able to create simulated satellite signals and generate real RF signals by first producing I/Q data and calculating the orbits of satellites at a user-defined time, location and trajectory. series GNSS simulators are designed to offer as much capability as needed by developers, integrators, and manufacturers of applications for global satellite navigation. Spectracom CTO, Mr. John Fischer explains, “We understand the needs for simulating GPS and GNSS signals varies as much as the applications themselves. 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 even 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 4 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), multi-path, white noise, interference, and much more. Tests can be performed anywhere, anytime, from the convenience of the test bench.

Spectracom CEO, Lisa Withers 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. 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.”
