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.

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.
On Friday, May 7, the Ingenuity Mars Helicopter left both Wright Brothers Field and the Perseverance Rover behind. Flying for 110 seconds, Ingenuity traveled 423 feet at a new height of 33 feet, capturing high resolution color images before landing at its new Red Planet home, which bears the tepid but significant name Airfield B. Ingenuity had become an operational scout in addition to its original role as a technology demonstrator.

A “non-recurring design validation” of a previously flown SpaceX Falcon 9 booster will be completed by the end of this month, in time to carry the next GPSIII satellite aloft, according to U.S. Space Force executive officer.

“Trains were born in Europe,” opens a recent report on European energy policy from the Jacques Delors Institute in Paris. So also, in some senses, were the Green movement and increased awareness of personal mobility options and potential. For the continent and the European Union community to maintain their world leadership in these two areas, the rail sector must play a greater role than it does presently, argues report author Matthias Ruete. He sees Galileo and EGNOS, the two European GNSS, as essential to this strategy.
