She was a former resident of San Mateo, Calif., Chicago, St. Paul, Minn., Bellaire, Mich. and South Padre Island, Texas.
As a statistician in 1962, with a Doctorate in Mathematics from the University of California at Berkeley, Charlotte Striebel developed the initial workings of GPS, global positioning satellites while at Lockheed Missiles and Space Company in Sunnyvale, Calif. while analyzing satellite tracking data and reliability of the Polaris Missile and Gemini space program manned space capsule reentry and recovery.
Charlotte was a professor of mathematics at the University of Chicago for two years before joining the University of Minnesota as associate professor. Her research involved the Optimal Control of Discrete Time of Stochastic Systems. In her spare time, Charlotte earned a law degree from the U of M and analyzed pay equity statistical models for equal pay for women from 1968 through 1994.
