Description
During a network measurement campaign 2015 the Leica laser tracker AT402 was considered and applied as a centred instrument. Therefore a methodology was developed to use it in such a way.
One aim was to analyse the precision of the centring of this instrument. Another task was the analysis how this method of reciprocal observations influenced the evaluation and especially the adjustment of the geodetic networks. Different combinations were investigated to get a better possibility in handling on the reliability, accuracy and comparability regarding future network measurement campaigns.
Further the distinctive possibility of the AT402 as a laser tracker and as a tachymeter was considered in several variants of evaluations which were taken with the program PANDA.
The single sub-networks were determined by laser trackers of different manufacturers. In some areas an overlap of such laser tracker measurements occurred so that the influence of the combination of different instruments was also analysed and investigated.
