The new GPS Military-Code (M-Code) Early Use (MCEU) hardware and software upgrade successfully took place on July 27 at the GPS Operational Control System (OCS) at the Master Control Station at Schriever Air Force Base, Colorado and Alternate Master Control Stations at Vandenberg Air Force Base, California.

The third next-generation GLONASS-K navigation satellite, postponed several times, will now take place in late August or early September, according to reported statements by Russian space industry sources. This marks a long-delayed step along a road towards interoperability with other GNSS. The first GLONASS-K satellite was launched in 2011 and a second one in 2014.

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.

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.

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:

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.

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.
Set 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!”
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.”
The UK Ministry of Defence Equipment and Support office tasked Raytheon to develop a prototype system to exploit assured and resilient position navigation and timing information derived from GNSS, according to a statement.

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.

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.

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.
