Erfahrungen mit dem Satelliten-Navigationssystem GPS - Genauigkeiten
an Land und auf See
Deutsche Hydrographische Zeitschrift 44, pp. 35...49, 1991
Abstract - -
Following a brief introduction into the GPS-System, results are presented and
discussed of tests of accuracy of one particular instrument.
Tests were made from both a fixed position and on board ship. Depending on the
geometry between the satellites an accuracy of 18 m in position and of 2 cm/s
in velocity can be obtained ( at σ and HDOP < 7). On the basis of
measurements on board ship, the dynamic resolution is shown to be better
then one meter, and both, roll and pitch can be resolved within this range.
The survey was conducted prior to activation of an intentional degradation
of the system by "Selective Availibility".
