Global Positioning Systems Focus of Humanists Science Sunday Program Dec. 6

Global Positioning Systems and how they work is the next Science Sunday presentation by the Central Colorado Humanists on Dec. 6.

The session will be presented by Bill Sample, who worked as an avionics systems engineer for 38 years, designing electronics for space vehicles as well as aircraft.

Sample worked on aircraft GPS since the first units were designed for civil aviation in the late 1980s. He is an experienced pilot with over 7,000 hours flying and holds air transport and flight instructor ratings in single and multi-engine aircraft.

Sample has also served on the Chaffee County Search and Rescue (SAR) South team for five years, serving on hiking teams, as part of the incident command team rotation as well as managing communication equipment and the technical aspects of drones used in search and rescue.

Sample will present a brief history of the U.S. GPS system and describe how the Global Navigation Satellite System, made up of satellite constellations of six countries, works and the coordination systems they use.

He will also explain using a GPS application on SAR missions and to support his outdoor hobbies.

The program will be presented starting at 10 a.m. on ZOOM.

The program will start promptly at 10 a.m., followed by a question-and-answer period.
