New Atomic Clocks to Get Precision Timing Down Cold, Back up GPS for Infrastructure

ColdQuanta received two development contracts from U.S. Government agencies worth $2.55M in total, based on the company’s Quantum Core technology that uses atoms cooled to a temperature of nearly absolute zero, and lasers to manipulate and control the atoms with extreme precision. According to the Boulder, Colorado-based company, cold atom quantum technology can be used for secure global navigation, quantum timekeeping, and communications.

Carpe Signum: Seize the Signal

Innovative features of cellular fifth-generation (5G) signals enable the wireless system to play a major role in autonomous technologies. Test results of a ground vehicle navigating with signals from five 5G base stations (gNBs) over a trajectory of 773 m traversed in 110 seconds show a position root mean-squared error of 4.1 m.

DOT Report on Backup PNT Technologies Finds NextNav Performs Best, Calls for Synthesis and Synergy

The Department of Transportation (DOT) submitted its “National Timing Resilience and Security Act: Roadmap to Implementation” report to Congress in mid-January. Following a competitive application process, demonstrations and review of 11 candidate technologies to back up GPS capabilities, the DOT concluded that “none of the systems can universally backup the positioning and navigations capabilities provided byGPS and its augmentations.” However, “all vendors demonstrated some PNT performance of value, but only one vendor, NextNav, demonstrated in all applicable use case scenarios.”
