Genene Fisher: Bringing Space Science Down to Earth

SIDEBAR: Genene Fisher’s Compass Points

As Solar Cycle 24 rolls around toward its maximum peak next May, when a hundred or more sunspots may appear during the course of a single day, no single navigator stands at the helm to guide the hundreds of companies, research groups, users, and policy workers through the uncharted realm of spiking solar activity and its inevitable effects on GNSS.

PNT Advisory Board Seeks Details on Economic Benefits of GPS

To help counter pressures from federal budget cutters and wireless advocates searching for more broadband spectrum, the National Space-Based Positioning, Navigation, and Timing (PNT) Advisory Board is crafting a study documenting the economic benefits of GPS.

“We have a new assignment . . . to discover and disclose the economic contributions of the Global Positioning System,” Chairman Jim Schlesinger told the board at an August 15, 1012 meeting of the advisory board.

One-Centimeter Accuracy with PPP

The navigation message has always been considered an inherent and essential feature of a global satellite navigation system. Its primary objective is to provide receivers with information on the errors of satellite clocks and parameters to compute the positions of satellites, as well as other parameters that help generate more accurate measurements.
