SBG Systems has released the Virtual Base Station feature in its in-house post-processing software called Qinertia. Geospatial professionals can benefit from an optimal centimeter-level position accuracy in all their projects, even for corridor mapping and in poorly covered RTK areas.
By Inside GNSS Data fusion from a range of sensors — GNSS, inertial, LiDAR, radar and more — to enable autonomous navigation is a highly complex operation that requires very sophisticated software stacks. A free webinar on October 27 presents leading-edge research and development in this realm that brings modular solutions ready to hand.
By Inside GNSS 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.
