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.

Collins Aerospace received a program-of-record contract to mature and integrate a positioning, navigation and timing system for the U.S. Army’s for the Army’s increasingly sophisticated manned ground vehicles. The Mounted Assured Position Navigation and Timing System (MAPS) will maintain the integrity of positioning and timing during operations in GPS-contested environments.

Laboratory tests explore how commercially available receivers respond to meaconing and spoofing, with the goal of developing useful test methodologies and metrics to assess receiver robustness and resilience to real-world spoofing threats.
The fifth GPS III satellite rising in 2021 will ride aboard a previously used Falcon 9 first-stage booster, in a first for a National Security Space Launch mission. Space Exploration Technologies Corporation (SpaceX) has contracted with the U.S. Space Force’s Space and Missile Systems Center Launch Enterprise to reuse the booster rockets.
