A novel method to track Galileo E5 AltBOC signal phase adjusts and then combines the correlation results of the upper sideband and lower sideband signal to form a double-sideband correlation result, which is equivalent to AltBOC wideband receiving to some extent. Thus, a Galileo E5 wideband receiver can be achieved with only minor modification to a traditional GNSS single-sideband receiver. The method can be further applied to other binary offset carrier (BOC) signals.

The Government Accounting Office (GAO) has issued a 51-page report examining the challenges the Department of Defense faces in developing and fielding new positioning, navigation and timing (PNT) technologies to complement, augment or replace GPS when it is unavailable. It found that the DOD is not doing enough in this regard.

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.
Hexagon | NovAtel has introduced the PIM222A, part of a new family of automotive GNSS positioning products for advanced driver assistance systems (ADAS) and autonomy. The PIM222A delivers precise positioning, velocity and attitude in the most demanding applications for mass deployment in ADAS applications and autonomous vehicles.
