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.

Emerged from Its Cocoon, the Third GPS III Now Flies Skyward

After a successful launch on the afternoon of June 30, the third Lockheed Martin-built GPS III satellite now heads to orbit under its own propulsion. The satellite has separated from its rocket and is using onboard power to climb to its operational orbit, approximately 12,550 miles above the Earth.

BeiDou Completes Inter-Satellite Link Testing; Only GNSS with this Accuracy-Improving Feature

The China Satellite Navigation Office (CSNO) announced completion of two years of testing of BeiDou inter-satellite links, an innovative feature of the GNSS that will reportedly produce greater accuracy for users on Earth. The test campaign encompassed 29 satellites of the third generation (BDS-3) of the now global system.

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.

New GPS Performance Document Gives Glimpses of L2C, L5, Expanded Constellation

The U.S. Air Force updated the GPS Standard Positioning System (SPS) Performance Standard (PS) in mid-April, 2020, the first new Performance Standard document since 2008. It includes mention of and pre-Initial Operating Capability (IOC) performance standards for the new civil GPS signals L2C and L5 for the first time. In another new feature, the document mentions “expanded capabilities which allow the total size of operational constellation to grow beyond the previous maximum of 32 Navstar satellites” for “more robust constellation availability to enhance the overall SPS SIS performance.”

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.
