On April 6, the GPS system used by many organizations for critical infrastructure will perform a rollover. The rollover is the result of a legacy GPS navigation message which gives a week number as a 10-bit parameter. As a result, the week number parameter in the GPS navigation message needs to reset to zero every 1024 weeks. That means from... read more

Request for Information pursues state-of-the-art technologies for collecting and characterizing 3D mapping and surveying data. DARPA is seeking information on state-of-the-art technologies and methodologies for advanced mapping and surveying in support of the agency’s Subterranean (SubT) Challenge. Georeferenced data — geographic coordinates tied to a map or image — could significantly improve the speed and accuracy of warfighters in time-sensitive... read more
Furuno Electric Co. Ltd., based in Nishinomiya, Japan, has developed the GT-88 timing module and GF-8801/02/03/04/05 disciplined oscillator for users who require UTC time-synchronized signals to meet the new 5G requirements. They provide UTC time-synchronized timing signals (1 PPS/10 MHz) by receiving GNSS satellite signals. Achieved stability is better than that of an atomic clock, including a rubidium. The GT/GF-88 series includes a... read more
