Global Navigation Satellite Systems Engineering, Policy, and Design
Testing of the first pair of Galileo Batch 3 satellites at the European Space Research and Technology Centre (ESTEC) was completed in April, and they are now in storage on site. Three more new Galileo satellites have since arrived from OHB in Germany

NASA has awarded a contract to the University of Michigan for the Cyclone Global Navigation Satellite System (CYGNSS) for mission operations and closeout. A constellation of eight microsatellites, the system can view storms more frequently and in a way traditional satellites are unable to, increasing scientists’ ability to understand and predict hurricanes. The total value of the contract is approximately $39 million. The CYGNSS Science Operations Center is located at the University of Michigan.

Work on the Galileo EU Defence (GEODE) program began earlier this year when a consortium of 30 organizations from 14 European Union (EU) member states met to initiate “the biggest Galileo application development project ever launched” and “one of the most ambitious defense cooperation projects launched under the umbrella of the European Defence Industrial Development Programme (EDIDP),” according to consortium leader FDC.

The UK Chair of the Parliamentary Space Committee David Morris reportedly sees a path back into Galileo participation for his country, thanks to a major investment from Europe into the OneWeb system, which the UK controls.

A new approach to achieving the safety needed for levels 3 and higher of autonomy builds on a thorough mathematical framework to support safety analysis, while delivering very tight position bounds.
On Memorial Day, just prior to the running of the legendary Indy 500 race, a new speedway star came out to shine. A driverless racecar, no less, aiming for track speeds above 120 mph with no human hands on the wheel.

The European Space Agency finally signed two contracts for an overall amount of €1.47 billion, to design and build the first batch of the second generation of Europe’s Galileo navigation satellites.

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.

The Defense Advanced Research Projects Agency (DARPA) has awarded Northrop Grumman a $13.3 million contract Phase 2 of the Blackjack program to “advance its Position, Navigation, and Timing (PNT) payload through emulation and Critical Design Review, and build PNT payload units destined for space flight.”
