Abstract

Ellipsoidal heights have been determined for a test network in Lower Saxony with GPS. The GPS results, with a relative precision of a few centimeters, have been used to compute quasigeoid heights by substracting leveling heights. This data set is compared to mainly gravimetrically determined quasigeoid heights using least squares collocation techniques. The discrepancies between the two data sets amount to about ±2 cm, the maximum interstation distance is about 50 km. This agreement shows, that GPS can be used in combination with gravity information to obtain normal heights with cm-precision.
