UrsaNav and ADVA have conducted an enhanced long-range navigation (eLoran) field trial using UrsaNav’s eLoran receiver and ADVA’s Oscilloquartz grandmaster clock technology. The successful demo showed that eLoran offers a robust and reliable backup for GPS and other GNSS and could be used to provide an assured position, navigation, and timing (PNT) service.

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.
