GSG-62 simulator Spectracom announced its new L1+L2 dual-frequency 32-channel multi-GNSS simulator, the GSG-62. The GSG-62 offers multiple frequency band operation, multiple GNSS constellation simulation, and expansion capability for more frequency bands and channels, the company said. The new simulator provides expanded capabilities for those who are testing more than GPS L1, according to the company. “We understand the challenges our customers have in fast-paced development, migration and delivery of products with ever changing embedded GNSS receivers,” said John Fischer, Spectracom CTO. “As such, we are excited to introduce this next-generation multi-signal instrument that allows for real-time scenarios, is intuitive to understand, quick to deploy and, given its design to support upgrades to L2C, L5, and future GNSS frequencies and systems, protects our customer’s investment in test gear.” Fischer continued, “In addition to a wide variety of technical challenges, we also understand our customers must balance the ability to quickly develop solutions and improve cost performance in their operations. We believe the price, unique features, and form factor of the GSG-62 will allow them to do both.” The GSG-62 is designed for manufacturing and development testing with its ability to simulate all the visible satellites for the receiver under test. With 16 channels for L1 frequency and 16 channels for L2 frequency, channels can be assigned to GPS or GLONASS, P-code or C/A code. Channels may also be used for SBAS simulation of EGNOS, WAAS, GAGAN, or MSAS satellites, or for multipath and interference signals. The GSG-62 incorporates all the features of Spectracom’s previous models, including compatibility with GSG StudioView PC software for creation and editing of simulation scenarios via Google Maps. Spectracom is a business of the Orolia Group and provider of practical test solutions for GPS and GNSS devices and systems.
