Expert Opinions: Buyers’ need for GNSS receiver testing, certification

August 29, 2016By
Dana-Goward

Q: Buyers get little guidance as to how specific receivers react to interference, particularly in critical infrastructure. Is there a need for receiver testing and certification along the lines of Underwriters Laboratories to guide purchase and acquisition? A: Exhaustive “seven-nines” testing and verification is expensive, takes a long time and stymies innovation. Yet simple and pragmatic testing can reveal faults... read more
