摘要

Reception system for the gps - positioning, while the use of the azimuth - distance - correction, the on the basis of gps - code solutions, which alf (accurate positioning by low frequency) measured dgps - positions is further improved, and thus also the occurring deviations from the desired value is reduced. Dollars a the position values are read from the nmea - module in a firm adco - module are processed further, wherein a correction quantity of an empirically determined correction curve and read off from the recorded position of the user in the direction of the reference station to be removed and this value to the user via a data interface and / or is passed on to a display. Dollars a the present invention is advantageously in the case of all positioning - and navigation used in front of gears, such as, for example, in agriculture, in the case of geo - information - systems, in the fleet and in the case of the track detection in rail transport. Dollars a, the reception system makes it possible, especially for lw dgps - services, in our case the alf (accurate positioning by low frequency) dgps - service of the deutsche telekom and of the federal criminal investigation office for cartography and apart (bkg), with the use of the correction method of the firm adco bkg a considerable improvement of the dgps - positioning in the coverage area of the transmitter (about 5 million km · 2·). In reatime, it is thus possible to achieve positioning & 1,5 m.
