The GPS (Global Positioning System) is an American navigation system by means of which the coordinates of any point on the earth can be determined.
A GPS receiver receives signals from various satellites, which give information as to the precise position of the satellites, from which they are received. The information contained in these signals is then used by the receiver to calculate its position on earth (latitude, longitude, height.).
Due to the high degree of precision achieved (in the order of centimetres), this system lends itself to surveying tasks.
A further area of application is computer-assisted sounding combined with a DPS survey. Here the pertinent anomalies are assigned real-time coordinates via a connection box, which considerably simplify retrieval after evaluation.
