Global Navigation Satellite Systems Engineering, Policy, and Design
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.

SIDEBAR: Michel Monnerat’s Compass Points
“I was born in Arles, in the south of France,” says Michel Monnerat, “but I left France before my first birthday. We moved many times, from place to place.”
Monnerat’s father worked for a civil engineering company, specializing in maritime works — harbor construction, coastal protection, and such. His family lived in Ivory Coast, Cameroon, and Tunisia, but Monnerat spent most of my early life in Lomé, the capital city of Togo.

SIDEBAR: Elizabeth Rooney’s Compass Points
Going for her first big job interview after college, Elizabeth Rooney admits she didn’t know what GPS was.
“It was 1995,” she says, “and I was going in to see about this job. I had been looking at some literature from the company I was interviewing with, and there it was, ‘GPS.’ I wondered what the letters meant when I saw them.”

I Fell In Love With GNSS When . . .
“Two GNSS-related experiences really impressed me as a young professional and that I’ve never forgotten. The first involved adjusting a GPS-supported (GPS aerial control) aerial triangulation. By getting rid of most ground control points we managed to produce new results.

SIDEBAR: Ismael Colomina’s Compass Points
Ismael Colomina began his career in 1982. “So, in a way,” he says, “I grew up as a professional at the same time GPS was growing up and maturing. GNSS has always been present in my working life; so, I never experienced the ‘GNSS, aha!’ moment. Rather, I never stopped thinking ‘GNSS, of course!’"

SIDEBAR: Di Qiu’s Compass Points
Landing all-weather aircraft safely in storms. Protecting sensitive data not only through encryption but based on the location at which it is being accessed. Ensuring that accurate and timely information reaches first responders responding to emergencies.
Although still in the early part of her career, Di Qiu has already made significant contributions to these crucial applications of navigation technology.
