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.”

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.

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.

Magnetic Sensors in Flight Tests as Alternative PNT to GNSS

A new magnetic anomaly navigation technique (MAGNAV), researched by the Air Force Institute of Technology (AFIT), will get its wings tested aboard F-16 fightercraft this September. In an effort seeking alternatives to GPS and GNSS, MAGNAV sensors and software will be flown on Air Force Test Pilots School (AFTPS) F-16s over a test range adjacent to Edwards Air Force Base in Nevada.

LEO Successor to GNSS Comes Knocking

A group of Stanford Ph.D. and Masters graduates, with work experience among them at SpaceX, Ford Motor Systems, Blue Origin, Booz Allen Hamilton and other firms, has launched a start-up to start up a low-Earth orbit successor to GPS and other GNSS. The existing services, they say, are not up to the challenges of autonomy. They founded Xona Space Systems to supplant the venerable satnav systems.

Galileo on PATROL for Driver and Road Safety

The Position Authenticated Tachograph foR OSNMA Launch (PATROL) project is developing the first external GNSS facility for smart tachographs, using Galileo’s new Open Service Authentication (OS-NMA). The tachograph, a device fitted to a vehicle that automatically records its speed and distance, together with the driver’s activity selected from a choice of modes, uses Galileo authentication to verify that the navigation data received from satellites is genuine.
