Probably no one else could have accomplished Brad Parkinson’s bravura performance at the joint meeting of the Stanford PNT Symposium/Marconi Society earlier this month: in the morning sketch a “short history” of radio waves from Marconi to GPS and in the evening recount a brief retrospective on the Global Positioning System from its prehistory in the 1960s to its future in the 21st century.
And in between moderate a panel of past Marconi Fellows, among whom Parkinson is the latest addition.

Working Papers • November/December 2016
Working Papers explore the technical and scientific themes that underpin GNSS programs and applications. This regular column is coordinated by Prof. Dr.-Ing. Günter Hein, head of Europe's Galileo Operations and Evolution.

Q: What are the challenges of ray-tracing for GNSS applications?
A: Simulating the propagation and reception of GNSS signals in complex environments is a challenging task. Indeed, the user always has to trade off between the computation time and the reliability of the output. Moreover, the motion of GNSS satellites, atmospheric effects, and building geometry are always difficult to model.
Inside GNSS • November/December 2016
Spacecraft in low Earth orbit (LEO), at altitudes below 3,000 kilometers, remain within the main Global Positioning System (GPS) signals’ Earth coverage. Spacecraft employing GPS at these altitudes enjoy signal availability and navigation and timing performance emulating that of terrestrial users.

NovAtel has signed a contract with Stanford University for a study to determine how GNSS technology can deliver a positioning system that meets safety and accuracy requirements for autonomous land vehicles, the company said.
NovAtel said the study, to be conducted at Stanford's GPS Research Laboratory, will build on similar aircraft research. In addition, the research will include concepts for high integrity carrier-phase algorithms, threat models, and safety monitors for improving autonomous vehicle transportation, the company said.
