January 10, 2017By

New cars for the Russian market must be equipped with the automatic ERA-GLONASS emergency call system. For certification of these in-vehicle systems, both conformance and performance tests are mandatory, in line with the Russian GOST R 55534 specification. For both types of tests, the Russian Certification Center Svyaz-Certificate uses standard-compliant test solutions from Rohde & Schwarz. Manufacturers and component suppliers... read more

Expert Opinions: Testing and simulating against GNSS jamming, spoofing

November 8, 2016By
satellites-500x150

Q: What special considerations should be taken into account for testing and simulating against GNSS jamming and spoofing?   A: Current integrations of GPS include a controlled reception pattern antenna (CRPA). Testing with a standard interference or jamming source will not provide accurate results. Wavefront generator simulators are capable of outputting signals that correctly stimulate the GPS receiver’s antenna electronics.... read more

Make it real: Developing a test framework for PNT systems and devices

OPENING GRAPHIC

Tests of the robustness of commercial GNSS devices against threats show that different receivers behave differently in the presence of the same threat vectors. A risk-assessment framework for PNT systems can gauge real-world threat vectors, then the most appropriate and cost-effective mitigation can be selected. Vulnerabilities of GNSS positioning, navigation and timing are a consequence of the signals’ very low... read more
