The long answer would involve taking a course on ‘Satellite Positioning’ in order to understand what happens to GPS signals as they travel from the satellites orbiting the Earth through the atmosphere and eventually received by the antenna somewhere above or on the Earth’s surface. This talk will provide a brief account of a signal’s journey from space to your training gear and diamond exploration activities. Current GPS technologies will be discussed along with the challenges posed by one of the most prevalent geospatial tools available today.
