webinar-june2014-W

The two GLONASS stumbles in May prompted industry leaders to again promote multi-GNSS user equipment and the development of of reliable back-up/redundant positioning, navigation, and timing (PNT) systems to cope with potential drop-outs of space-based services due to jamming, unintentional interference, spoofing, or other disruptions. But neither multi-GNSS nor back-up/alternative PNT fully exists at this time, effectively for all users.... read more
