Skydel SDX Release 17.1 adds a fine level of control on signal multipath to the software-defined GNSS simulator. SDX 17.1 introduces a powerful multipath simulation option, enabling users to create less-than-ideal signal propagation conditions for GNSS testing. Multipath echoes can be added and fined-tuned for each satellite, per signal. Control is possible via four fundamental attributes: pseudorange offset, power loss, Doppler shift... read more

Emerging GNSS applications in automobiles support regulation, security, safety, and financial transactions, as well as navigation, guidance, traffic information, and entertainment. The GNSS sub-systems and onboard applications must demonstrate robustness under a range of environments and varying threats. A dedicated automotive GNSS test center enables engineers to design their own GNSS test scenarios including urban canyons, tunnels, and jamming sources at a controlled test site. read more
