| Global Positioning Systems or GPS is a position-finding system which uses radio receivers to pick up signals from four or more special satellites (there are 24 in orbit) and compute co-ordinates for the receiver. The position accuracy depends on the sophistication of processing and the time available for reception. Real-time navigation using GPS on aircraft and ships can be to better than 10m. Processed data from several hours observation can provide relative positions accurate to centimetres. Devices can now be used in cars and by individuals to navigate to there destinations or find their location. | ||
