Global Navigation Satellite Systems Engineering, Policy, and Design
A study by the U.S. National Institute of Standards and Technology (NIST), the U.S. Government agency responsible for maintaining national time scale, shows that Satelles’ Satellite Time and Location (STL) provides a signal that is independent of GNSS with exceptional timing stability and reach that extends indoors, beyond the range of GNSS signals.

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.

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.”

The European GNSS Agency (GSA) released a new Galileo Open Service Signal in Space Interface Control Document (OS SIS ICD), the second issue of this document geared towards GNSS receiver manufacturers. Although the modified signals are not yet broadcast by Galileo satellites, the ICD will allow GNSS receiver manufacturers to prepare for the improved signals, set for debut in 2023.
