Rome wasn’t built in a day, and neither was the Global Positioning System.
Nor will the emerging GNSS system of systems arising from the regional and global infrastructures being put in place or modernized today: GPS, GLONASS, Galileo, Compass (Beidou-2), QZSS, GAGAN, IRNSS, EGNOS, WAAS, MSAS, and undoubtedly other acronyms yet to be born.

Trimble introduced its new Trimble BD970, a real-time kinematic (RTK) GNSS receiver for high-precision and control application, at the ION GNSS 2009 show in September.
Capable of receiving a wide range of commercially available satellite signals, the BD970 receiver is designed to allow OEMs and system integrators to easily add centimeter-level positioning to specialized or custom hardware solutions.

My history with GPS began during the time of the “Cold War” in what was then Czechoslovakia. In 1975, the ION Journal of Navigation was the only information available to me. Despite that, my team at the Czech Technical University developed a GPS receiver and measured the position of our faculty in 1984. In those relatively isolated years, we gained a good deal of experience with GPS signals.

The recent GAO report and Government Oversight subcommittee hearing on GPS sustainability generated more heat than light, with some major news media outlets leaving the impression that the sky (or at least GPS satellites) would soon be falling.
Perhaps the only silver lining in the ensuing Chicken Little phenomenon was the crude measure it provided of just how familiar (but not necessarily knowledgeable) private citizens have become with GPS.
