Global Navigation Satellite Systems Engineering, Policy, and Design
The GPS program is setting a new space-system standard for cyberdefense, and now the federal government is creating a framework to help operators of critical infrastructure that largely rely on GPS to do the same.
The need to raise the bar is clear. Malicious coders, often backed by hostile nation-states or criminal organizations, are using automated tools to continuously probe for weaknesses:

GPS/BeiDou/MEMS configuration and GPS/MEMS configuration (left and right, respectively, top photo), Front view (center photo) and back view (lower photo) of nAX5.2Due to the huge success of GPS in both military and civil applications, several other GNSSs have been developed, built, and operated in the last few decades. GNSS, regional, and augmentation systems are comprise a growing family that also includes GLONASS, Galileo, BeiDou, and Japan’s Quasi-Zenith Satellite System (QZSS). New members, such as the Global Indian Navigation System (GINS), are preparing to join in next decade.

As engineers painstakingly work their way through tests of the first full operational capability (FOC) Galileo satellite at the European Space Agency’s European Space Research and Technology Center (ESA/ESTEC) in Noordwijk, The Netherlands, European space sources have acknowledged that the new-generation spacecraft’s maiden voyage will not occur until December 28, and even that date looks highly unlikely.

Ismael Colomina, wife Carmina, and children Jan and Eulalia on vacation in BrazilI Fell In Love With GNSS When . . .
“Two GNSS-related experiences really impressed me as a young professional and that I’ve never forgotten. The first involved adjusting a GPS-supported (GPS aerial control) aerial triangulation. By getting rid of most ground control points we managed to produce new results.
