[QUOTE="BigWave, post: 595336, member: 6786"] Hey Doug. With only 2 satellites a GPS receiver will calculate 2 points on Earth. With 3, it will eliminate one but won't show altitude. With 4 satellites, altitude will be calculated. More satellites will improve positioning as they will provide better geometries (i.e.: two lines intersecting at low angles give more error than two lines crossing at high angles). The GPS will track all visible satellites and select the satellites giving the best receive power and geometry. [/QUOTE]
