Global Navigation Satellite Systems Engineering, Policy, and Design
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.

The Institute of Navigation premier conference, ION GNSS+ 2020, held annually in September, will this year have a virtual option for attendance. It will mirror the technical program presented live, September 21-25 in St. Louis, Missouri, and will give global attendees access to the latest GNSS developments and content. Virtual meeting attendance will be free for all first-time ION GNSS+ attendees.

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.

We cannot simply test-drive our way to safety. Instead, innovative methods of demonstrating safety and reliability must come into play immediately.
A free three-hour professional training over two days in June aims to show how.

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.

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.

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.”
