Green Lane Speeds Border Crossings of Essential Goods

Galileo Green Lane, a new mobile app, facilitates the free movement of freight, reduces waiting times at European Union borders, and prioritizes essential goods during pandemic response. The app uses Galileo positioning services  to address the needs of border control authorities and truck drivers, with two intuitive user interfaces. The app was developed by the European GNSS Agency (GSA) in collaboration with the European Commission.

5-cm Accuracy in Marine-Certified Receiver: Quad-Band Device Supports PPP Corrections

new marine-certified quad-band GNSS receiver, the LD900 from VERIPOS, delivers accurate, reliable positioning in demanding offshore environments. The LD900 can track four GNSS frequencies simultaneously to ensure a precise position is always available at sea. When combined with Apex5 correction services from VERIPOS, it delivers accuracy levels as precise as 5 cm (95%) to provide robust positioning for the most challenging applications, including deepwater drilling, seismic, construction, and survey.

The New Flex Power Mode: From GPS IIR-M and IIF Satellites with Extended Coverage Area

GPS satellites usually transmit their signals with constant power. However, a so-called “Flex Power” is foreseen to increase the strength of individual signals to better fulfill operational constraints. Flex power operations can be detected in carrier-to-noise density ratio (C/N0) observations provided by GNSS receivers of the global tracking network of the International GNSS Service (IGS).

Positioning, Navigation, and Timing Trust Inference Engine

Critical infrastructure has a compelling need to infer the assurance of PVT estimates—as do users in general. However, traditional PNT platforms do not offer a principled way to infer assurance from multiple anti-spoofing (A-S) techniques, situational awareness (SA) information, and other auxiliary sources such as network data. Here we introduce, a PNT Trust Inference Engine (PNTTING) that can assess PNT trust according to probabilistic models with rigorous semantics.

Knives Out

The Federal Communications Commission should really consider updating its motto. “Firm, fast, flexible, and fair” has a bit of an old-fashioned ring. As mottos go, it fails to keep up with the times.
