Global Navigation Satellite Systems Engineering, Policy, and Design
VectorNav Technologies, the world leader in embedded navigation solutions, introduced today a groundbreaking new line of inertial products: the VectorNav Tactical Embedded. Featuring a tactical-grade IMU and a multi-band GNSS receivers, the Tactical Embedded delivers milliradian attitude accuracy and centimeter-level positioning capability in a miniature 15 gram package.
By Inside GNSS The United Arab Emirates will launch a navigation satellite in 2021, according to the Emirates News Agency. “The first satellite will be launched in 2021 and the second — a technologically enhanced one — the following year,” said Dr. Khaled Al Hashmi, Director of the National Space Science and Technology Centre (NSSTC) at UAE University in Al Ain.
By Inside GNSS 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.
By Inside GNSS Spirent Communications has released SimIQ, a new software that enables earlier and more efficient GNSS testing during product development. It accomplishes this by extending multi-frequency, multi-constellation simulation capabilities to cover software-only testing needs.
By Inside GNSS 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:

The Satellite-Based Augmentation Systems Interoperability Working Group has grown from 4 members in 1997 to more than 10 now, and logged significant progress in forming a global aviation support system.
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.

An on-board spoofing detection unit collects metrics from the GNSS signal processing chain and provides a real-time indication if the receiver is under spoofing attack. Test results from several spoofing scenarios are based on GNSS hardware simulations, repeaters and software-defined radios.

When we find ourselves in times of trouble, it can help to take the long view. Pull back, zoom out, range free. Consider a vastly enlarged scope and sequence.
That’s why I find this month’s NTS-3 story so welcome. “Next-generation technologies across space,” I keep repeating.
