Karen Van Dyke: Re-Engineering the Airways

Someday, coordinates will be part of every product and process in our lives, says GPS innovator Karen Van Dyke of the Volpe Transportation Systems Center. As one of the engineers working towards that goal, she uses GNSS to make the air transportation infrastructure more reliable, less vulnerable, and easier to monitor.

When one GNSS system needs to gets up to speed, the others pick up the slack
In an industrious and cooperative surge of activity, we have seen three sets of draft specifications reach fruition in the last few weeks: publication of a joint recommendation for design of new civil signals on GPS and Galileo, the Galileo Interface Control Document, and the GPS L1C interface specification.

MBOC: The New Optimized Spreading Modulation

Recommended for Galileo L1 OS and GPS L1C
This article introduces the multiplexed binary offset carrier (MBOC) spreading modulation recently recommended by the GPS-Galileo Working Group on Interoperability and Compatibility for adoption by Europe’s Galileo program for its Open Service (OS) signal at L1 frequency, and also by the United States for its modernized GPS L1 Civil (L1C) signal. The article provides information on the history, motivation, and construction of MBOC signals. It then shows various performance characteristics and summarizes their status in Galileo and GPS signal design.
