Spectracom’s GSG-6 Simulator with monitor. Spectracom has begun a program to develop robust application-specific testing solutions. The program fills what the company calls a technology and expertise gap in providing customers in a variety of industries the tools to perform more comprehensive qualification of their mission-critical systems. Examples of these industries include: multi-constellation (GPS, GLONASS, Galileo, BeiDou) simulation; integrated MEMs/INS testing; interference detection and mitigation (IDM) verification; assisted-GNSS (A-GPS) validation, hardware-in-the-loop (HIL) testing for automotive applications; high-dynamic platform simulations for aerospace and defense (UAVs, UASs); and precision agriculture/surveying testing via RTK/differential measurements. “Our full featured platform of multi-GNSS simulation capabilities  combine flexible hardware and user oriented software to deliver  the functionality and user interfaces necessary for today’s demanding test scenarios,” said Spectracom CTO, John Fischer. “We understand, however, that even the most powerful tools often need something more to reduce complexity, increase productivity and ensure consistent, reliable results. Toward these ends we are excited to bring our extensive applications knowledge directly to our customers to design and deliver custom configurations and test systems that are unique to their applications.” Today’s PNT applications combine data from a variety of receivers, sensors and other sources. Spectracom is designing its solutions to integrate simulated GNSS RF with all other data sources in the test system for true “hardware-in-the-loop” verification, the company said. For instance, Spectracom’s new assisted-GNSS (A-GNSS) feature is designed to integrate with 3GPP/LTE testers to send “assistance data” directly to the device under test. The company takes a similar approach to testing RTK-enabled receivers with user-settable virtual base-station parameters. “Spectracom’s value is to partner with our customers to ensure they have the ability to easily use GNSS simulation as part of a comprehensive PNT testing solution,” said Rohit Braggs, Director of Marketing and Strategy. “More testing in the lab enables faster time to market, at a reduced cost and increased reliability. We are asking developers of the most demanding PNT applications to put us to the test.”
