Global Navigation Satellite Systems Engineering, Policy, and Design
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.
By Alan Cameron
This advanced geosynchronous satellite from the Air Force Research Laboratory will mature next-generation technologies across space, ground control, and user equipment segments. NTS-3 will experiment with multiple integrated technologies.
Ramjack Technology Solutions and Syntony GNSS have partnered to deliver underground GNSS positioning, navigation and timing (PNT) solutions, using Syntony’s SubWave technology.

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.

The European Space Agency (ESA) has recently launched an internal initiative to cull ideas for supporting its member states in the study and analysis of the COVID-19 pandemic. Under this initiative ESAC’s Galileo Navigation Science Office has managed to get one of its ideas taken up under the name of the “COVID-19 Space Hunting Platform”.

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.

The European GNSS Agency (GSA) has published a White Paper on “Power-efficient positioning for the Internet of Things,” providing an overview of GNSS technologies that are relevant for low-power IoT applications, including those that require hybridization with other connectivity solutions.

The Institute of Navigation (ION) announced that its annual ION GNSS+ 2020 conference, scheduled to take place September 21-25, will now be held entirely virtual. InterGeo, the large international trade show held each fall in Germany, has made a similar announcement for its conference, scheduled for October 13–15.

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.

Silicon Sensing Systems’ high performance DMU30 micro electro-mechanical systems (MEMS) inertial measurement unit (IMU) has been selected by the Institute for Q-shu Pioneers of Space, Inc. (iQPS) of Fukuoka, Japan, for the control system of Japan’s first X-band synthetic aperture radar (SAR) small satellite.

MEMS has moved into the high-end market, and the latest disruptor to take into account is silicon MEMS. That’s micro-electromechanical systems based in silicon chips, for short. Accelerometers with up to 100g range and 70µg bias in a very small form factor — 6 cubic centimeters — are exploding the horizons for inertial applications.
