NextNav, a provider of 3D geolocation, announced the availability of its vertical positioning service in sixteen major metropolitan areas in the US. The vertical positioning service helps first responders find people — via their cell phones or tablets — faster in multi-story buildings, opens up new urban markets for location-based applications, and unlocks a new ecosystem of 3D geolocation products.

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.

The GNSS User Technology Report 2020 from the European GNSS Agency (GSA) analyzes the latest GNSS trends and developments as the GNSS industry broadly adopts multifrequency receivers across market segments.

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.”

A favorable GAO ruling discounted Congressional allegations that the FCC skipped a key legal step before granting Ligado’s controversial application. This positions the broadband company closer to its target and to ongoing interference with GPS signals.

Microchip Technology’s new time and frequency server with an embedded M-Code GPS receiver gives protection to military communication systems, radar and networks from the threats associated with intentional GPS jamming and spoofing, as well as cybersecurity risks to critical infrastructure.

The European GNSS Agency (GSA) has published a White Paper on “Power-efficient positioning for the Internet of Things,” providing an overview of GNSS technologies that are relevant for low-power IoT applications, including those that require hybridization with other connectivity solutions.

Britain has signed a £900 million ($1.135 billion) deal to buy a part share of satellite operator OneWeb, a low-Earth orbit constellation in-the-making, designed to provide global high-speed broadband services. There had been speculation that the government intended thereby to generate its own satellite-based navigation signals, as it has been shut out of Galileo security signals by its Brexit move. Some satnav experts quickly dashed that notion, but others demonstrated that it just may be possible.
