BeiDou Conducts Laser Communication Experiment, Steps Ahead of U.S. — Could Improve SatNav Accuracy

In a race with the U.S. to develop a laser communications network in space, China’s BeiDou GNSS has conducted an inter-satellite and satellite-ground station experiment using using lasers rather than the usual radio signals. The technology could potentially transmit data a million times faster than by radio signal to almost any location. Some experts say it could increase satnav accuracy by a factor of 6 to 40

GNSS Backup eLoran Trialed Using Grandmaster Clock

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.

New Microsoft Cloud Identity App Uses GPS to Defend Against Hackers

Microsoft has added identity and access management capabilities employing GPS among other factors to its Azure Active Directory, a cloud identity solution, to counter sophisticated hacking techniques. Two-factor authentication is no longer sufficient to defend against malicious entry. The GPS-based named locations and filters look at a range of signals for authorized user access.
