Galileo’s High Accuracy Service: Field Experimentation of Data Dissemination Schemes

Galileo will provide a High Accuracy Service (HAS) with positioning performance in the 20-cm range, disseminating Precise Point Positioning (PPP) corrections through the Galileo E6-B signal. Test results of a data encoding and dissemination scheme in different user environments demonstrate a reception time of the corrections in a few seconds in good channel conditions, and less than half a minute with severe channel impairments.

Time and Frequency Server with GPS M-Code Receiver

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.

Now Operational, BeiDou Could Conceal Cybersecurity Threat

As the final BeiDou satellite reaches geostationary orbit, experts in the satnav community worry about security implications of the now officially operational Chinese system. As a two-way rather than a one-way communication system, BeiDou differs in two key aspects from other GNSS:

Senator Takes a Stand for GPS

U.S. Sen. Jim Inhofe (R-Okla.), chairman of the Senate Armed Services Committee, announced that he has placed a hold on the nomination of Mike O’Rielly to a third term as Federal Communications Commision (FCC) Commissioner until O’Rielly publicly commits to vote to overturn the current Ligado Order.

Nobody’s Fool: Spoofing Detection in a High-Precision Receiver

An on-board spoofing detection unit collects metrics from the GNSS signal processing chain and provides a real-time indication if the receiver is under spoofing attack. Test results from several spoofing scenarios are based on GNSS hardware simulations, repeaters and software-defined radios.

The Time and the Place: The Long View

When we find ourselves in times of trouble, it can help to take the long view. Pull back, zoom out, range free. Consider a vastly enlarged scope and sequence.

That’s why I find this month’s NTS-3 story so welcome. “Next-generation technologies across space,” I keep repeating.

Galileo Saved in Latest EU Budget Slash

The European Commission cut its space budget for the next seven years but kept the Galileo and Copernicus satellite programs largely on track. The move came after intense negotiations over a 1.8-trillion-euro European Union budget seeking to absorb and remedy economic impacts of the coronavirus pandemic.

GMV leads development of ESA’s COVID-19 Space Hunting Platform

The European Space Agency (ESA) has recently launched an internal initiative to cull ideas for supporting its member states in the study and analysis of the COVID-19 pandemic. Under this initiative ESAC’s Galileo Navigation Science Office has managed to get one of its ideas taken up under the name of the “COVID-19 Space Hunting Platform”.

MyGalileoDrone Contest Open For Submissions

The European GNSS Agency (GSA), the operational agency of the European Commission for Galileo and EGNOS, is launching its MyGalileoDrone competition on July 17. This contest is targeting the design and development of drone-based applications or services, using a Galileo-enabled receiver, that address the EU’s key priorities such as the Green Deal, and support the EU Recovery Plan for Europe.
