www.reelschematic.com Reference www.reelschematic.com GPS: How It Works The global positioning system is a satellite-based GPS: navigation system consisting of a network of 24 orbiting How It Works satellites that are twelve thousand miles in space and in six different orbital paths. The satellites are constantly moving and you can receive satellite signals anywhere in the world, at any time. -

www.reelschematic.com Reference www.reelschematic.com DGPS: How It Works DGPS: Differential GPS (DGPS) is a technique used to How It Works improve the accuracy of the Global Positioning System. DGPS reduces the effects of ionospheric variations and can improve position accuracy typically to 1-5 meters. The DGPS Beacon Transmitter is placed at a known location (i.e., the exact position of the site has been previously determined). -

www.reelschematic.com Reference www.reelschematic.com Sources of Error Using a DGPS Beacon Receiver with your existing Sources of GPS Receiver can provide substantial improvements in Error accuracy; however, there may be occasions when the best possible accuracy will not occur. Several factors can contribute to a degraded DGPS accuracy. -
