Multi-antenna carrier-phase differential GNSS (CDGNSS)-based pose (position and orientation) estimation aided by monocular visual measurements and a smartphone-grade inertial sensor form the core of a system designed for micro aerial vehicles. It can be applied generally for low-cost, lightweight, high-accuracy, geo-referenced pose estimation.
The year 2020 was definitely one for the history books. The global pandemic forever changed life as we know it, and in its midst, our GPS development and production teams launched us deep into a new era of positioning, navigation, and timing (PNT) capabilities.

A consortium is preparing to ramp up production of Geonav IoT, a seamless indoor/outdoor positioning solution for sports applications, asset tracking and aiding drone traffic management. The GNSS module is a high-accuracy, dual-frequency system-on-chip with an integrated, low-power application processor.
One hundred days into the administration and the federal civil service crew has set the stage for the Biden team on the tough Positioning, Navigation, and Timing (PNT) issues they face: the Ligado debacle, interference concerns and a troubling lack of system redundancy or resiliency.
Official broadcast for testing of the Galileo High Accuracy Service (HAS) has begun. Users equipped with a receiver that is capable of acquiring this signal and extracting its data content can start observing and testing specific aspects of the HAS service

In May the former European GNSS Agency (GSA) officially rechristened itself as the European Union Agency for the Space Programme (EUSPA), marking the start of a new era for the EU space effort. Building on the legacy of the GSA, EUSPA will take on more responsibilities to create opportunities for EU citizens and the economy.

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.
