In 2005, Alison Brown was the first Sidney Sussex College woman alumna to be named as an honorary Fellow in recognition of her distinguished technical contributions. Pictured here with Keith Glover, now head of engineering at Cambridge University, who taught Brown control systems engineering, and Donald Green, her director of studies while she was an undergraduate.SIDEBAR: Alison Brown’s Compass Points
On display in the Smithsonian’s “Time and Navigation” exhibit in Washington D.C. is the world’s first GPS-enabled cell phone. It was developed in 1995 by NAVSYS Corporation, a Colorado GNSS and inertial R& D company, as part of the push to build a national emergency notification system for mobile users, E911.

Scintillation — rapid RF signal frequency and amplitude changes due to signal propagation path changes and phase shifting caused by solar turbulence in the ionosphere — is well known in the GNSS community. However, conclusive scientific studies that cover the whole extent of the question are hard to find. Galileo In-Orbit Validation Experiment (GIOVE) data processing confirmed the effects of scintillation on GNSS receivers, as described in the paper by J. Giraud listed in the Additional Resources section near the end of this article.
