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.

Light Relief: GNSS Buddy Road Trip

In a feelgood two-and-a-half minute video cartoon aimed well below its audience’s head, the XinhuaNet.com news service explains BeiDou advantages over GPS and other GNSS. Principally, the script stresses the satnav system’s two-way short message service (SMS) texting capability that can stand in for cellular communications in remote areas and in case of natural disasters that may disable cellular base stations.

Beidou4Set to a loping synthesized country rock soundtrack, the entertainment-with-a-message follows a passenger bus through a remote desert. When Buzz the Driver, spooked by a snake, deviates from his planned course, a BeiDou monitoring station quickly detects the error, generates an alarm and sends a message: “Hey, keep yourself focused!”Beidou

The animation gives a nod to other GNSS by stating that “Me and other family members are compatible and interoperable at the user level, which allows us to work together.”

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.

Cyber Attack Disables Private Pilots, GPS Fitness Users

Hackers exposed another vulnerable chink in U.S. national infrastructure over the weekend, in an attack on GPS manufacturer Garmin that began late Thursday, July 23.  Although the cybersecurity strike, apparently aimed at extorting a ransom, did not explicitly include the GPS signal, it disabled two large GPS user communities: general aviation (private pilots and some larger commercial flight operators) and fitness enthusiasts. Both found their Garmin devices and apps unresponsive.

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.

UK Acquires OneWeb LEO Constellation, But Won’t Work for SatNav — Or Maybe It Will

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.
