S.E.A. Datentechnik, a German developer and system integrator for advanced RF and V2X test and measurement systems, has announced an agreement with French firm M3 Systems to be a technology partner for advanced GNSS emulation technology. The two companies are well-established partners for the NI platform.

“We are sure that the cooperation of our companies provides high value for customers for the development, validation and production test of actual and future V2X and connected car technologies,” explained Gerd Schmitz, co-founder, and CEO of S.E.A. “The combination of M3 Systems’ deep experience with GNSS technology and S.E.A.’s competence and experience with V2X products provides tailored best-in-class test solutions for reasonable cost.”

Modern and future transport applications rely on GNSS services for localization and for timing for communication purposes. Therefore, the provision of a high-quality simulation of GNSS signals for the different constellations like GPS, Galileo, Glonass and BeiDou are required for V2X and ADAS test system applications.

S.E.A. says that its compact, automated turnkey test systems enable the efficient and reliable test of V2X technologies using scalable software and hardware components. The company’s modular V2X test platform is based on Software Defined Radio (SDR) technology and comprehends all aspects of automated V2X testing, including measurements on the physical layer for RF compliance, protocol or production test, protocol level test as well as integrated V2X traffic scenario simulation for testing V2X applications. International V2X standards for North America, Europe and China are supported for scenario-based testing by open-loop or closed-loop HIL systems. Test catalogs for specific test applications like RF-conformance measurements and V2X day 1 use case testing are available for efficient use of the flexible test systems.

The company claims that its SDR approach ensures early, independent availability of technologies such as DSRC and C-V2X today – and 5G-NR V2X in the future – featuring special functions for validation and verification test, even in early implementation stages. The high flexibility of this approach ensures independence from silicon-based (chipset) solutions, enables ultimate performance for V2X simulation and provides unique features for signal analysis and communication for test purposes and field analysis. SDR-based mobile SEA V2X sniffers capture protocol and RF information in one easy-to-use device for DRSC and C-V2X.

Meanwhile, M3 Systems’ StellaNGC software suite can be integrated seamlessly into the test environment. The application of the NI PXI platform for GNSS and communication emulation enables the integration of GNSS as well as other sensor and communication technologies such as radar, lidar and cameras for full closed-loop (HIL) ADAS/autonomous technology test systems.
