In 2018, when the UK’s post-Brexit involvement in Galileo was still a point of contention between London and Brussels, UK ministers set aside £92m to study the feasibility of building a sovereign satellite-navigation system. Almost immediately, the UK Space-Based Positioning Navigation and Timing Program (SBPP) became something of a political football, or soccer ball if you prefer. Critics and supporters chimed in vehemently at any piece of news. Why an independent UK PNT system might be necessary remains a reasonable first question for some observers.

The U.S. Space Force, Space and Missile Systems Center (SMC) and its mission partners successfully launched the Lockheed Martin-built fourth GPS III satellite at 6:24 p.m. Nov. 5 from Space Launch Complex 40 at Cape Canaveral Air Force Station, Florida. The satellite was carried to orbit aboard a Space Exploration Technologies Corporation (SpaceX) Falcon 9 launch vehicle.

Leidos showcased its system for airborne navigation in GPS-denied environments at the recent Association of the United States Army (AUSA) 2020 conference in Washington, D.C., October 11–13.The system, called Assured Data Engine for Positioning and Timing (ADEPT), compares the high-resolution camera view below a plane to a detailed satellite map.

Ambiguity resolution combined with multiple constellations and multiple frequencies proves very effective in reducing Precise Point Positioning convergence time. Such a solution with a 30° mask has a shorter convergence than a float multi-GNSS solution without any obstructions, despite the latter using more satellites.

Hexagon introduced a news survey-grade GNSS RTK rover with visual positioning at the InterGeo expo in Berlin. Designed for surveying professionals to measure points which previously could not be measured with a GNSS rover easily and accurately, the Leica GS18 I captures the site in images and measures points from them, either in the field or later in the office.
