Global Positioning System Activities
The Global Positioning System (GPS) provides accurate, continuous, worldwide, three-dimensional positioning, velocity, and precise timing measurements to a user located on the ground, in the air, or on, but not under, the water. The GPS handheld receiver is frequently used by a variety of people including military personnel, surveyors, boaters, pilots, hunters, hikers, and others.
In this activity, students investigate the minimal number of satellite signals needed to determine a 2-dimensional position (latitude and longitude) on the earth. Students will also determine their position and calculate differences between positions.
In this activity students use the Global Positioning System (GPS) handheld receiver to determine their track as they walk the perimeter of several polygons. Students will also calculate their average speed after walking a specified distance.
This activity explores how distances and areas of convex polygonal plots of land (and concave plots with modification) can be determined using a GPS, the Geometer's Sketchpad, and Excel.
