Six months ago, the FCC unanimously granted Ligado’s amended license modification applications to deploy a low-power terrestrial nationwide network in the L-Band. Petitions for reconsideration remain pending, interest groups continue to agitate for change, Congress awaits answers to conflict-of-interest questions—and Ligado presses forward as planned.

A broad cross-industry coalition sent a strongly worded letter to the Senate Commerce Committee warning that the Federal Communications Commission’s (FCC’s) Ligado Order that impacts GPS, if left in place, “would upend decades of sound spectrum policy, negatively impact a significant cross-section of commercial, federal, and academic users who rely on the many different L-band satellite services, and threaten the safety of most Americans.”

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.
