Rx Networks announced global availability of their streaming ephemeris assistance data for A-GPS location services. Up till recently, I thought mysterious mathematical algorithms and atomic clocks magically produced assistance data in underground Cheyenne Mountain GPS labs. Oddly enough, a college-roommate buddy of mine who is an RTK DGPS surveyor informed me that assistance data can be captured with 3 stationary bluetooth GPS pucks and a laptop, and distributed as a service with the same laptop. Surely that’s not 99.99% available, but add a server for scalable service access, and the tools of production and distribution are democratized to a point where you wonder why such a service warrants a $3.3 million investment.
