An automation gravity measurements with using PDA computers

Preliminary processing of relative g measurements, including height, tidal, drift corrections and error analysis, was possible inthe field by use of GRAW22 software. Program has been developed at the Warsaw University of Technology in nineties of previous century in OPL language to PSION microcomputer (Pachuta at all, 2001). Newer field computers, enabled more computational power and modern programming languages, allowing wider programming possibilities. New software to field operations connected with relative gravity measurements has been developed on WindowsCE platform – by GRAVANALYSER. Software can be used on different palmtops and supports every steps connected with gravimeter reading, computation of corrections and strategy of processing. In this paper short description of such software is presented. Differences between selected strategies of drift and tidal corrections computation are also presented.
