One of the more surprising consequences from the March 2011 earthquake in Japan was that the forces unleashed shifted the earth's mass sufficiently to accelerate its rotation, shortening each day by no less than 1.8 microseconds, according to calculations by NASA. And while such effects are clearly imperceptible to humans, their cumulative effect on GNSS timekeeping would cause significant inaccuracies that would be unacceptable to any GNSS application. Each GNSS will deal with the tim...

In the past, designers of satellite-based navigation systems have been mostly restricted to using a single system and service, the GPS C/A code. The current revolution in the industry is giving rise to not only new GNSS systems, some GNSS systems, notably GPS and Galileo, have multiple services available to the commercial GNSS designer. The question of which system or blend of systems a GNSS designer should consider, along with the potential for multiple services is thus an entirely ne...

As new GNSS systems appear, it becomes more apparent that you need a Multi-GNSS test solution. Here at Spirent we’ve been advocating Multi-GNSS for quite some time but now someone else has taken up the mantle. If you haven’t already done so, check out this comprehensive article in Inside GNSS magazine. Three receiver designers and researchers explain how they view Multi-GNSS simulators as an essential tool throughout the entire receiver development cycle: from research, development, de...
