GPS Modernization and GNSS
GPS, put in place with amazing speed considering the technological hurdles, is now critical to all sorts of positioning, navigation and timing around the world. It’s that very criticality that requires the modernization. The oldest operational satellites in the current constellation were launched in the 1990s. Imagine using a personal computer of that vintage today. It is not surprising that there are plans in place to alter the system substantially. What might be unexpected is many of those plans will be implemented entirely outside of the GPS system itself. GNSS, the Global Navigation Satellite System is here. New capabilities are available. It is prudent to consider the ramifications of a constellation including QZSS (Japan), GLONASS (Russia), Beidou (China), GALILEO (EU), Nav1C (India) and GPS satellites. Today there may be as many as 20-30 navigational satellites above your horizon. That provides you with much more and different capabilities than were available just a few years ago. How all this works is the subject of this seminar.
