MERIDIAN is a 120° east ground based multi-station and multi-instrument project proposed in China.
In the present multi-station and multi-component inversion, data covariance matrix C D has block structure.
The essential features of an OSCE of high quality include a well-planned blueprint with multi-faceted tasks and multi-stations and well-trained SPs and raters [ 16].
The results also show that MWD tool with in-field referencing (IFR) and multi station analysis (MSA) provide higher positional accuracy than the generic gyroscopic tools.
In order to detect the motion error of machine tool quickly and accurately, the multi-station and time-sharing measurement by laser tracker is introduced in the paper.
The hybrid genetic algorithm derived is used to determine the position of base station and the coordinates of measuring point, and the simulations and experiments are conducted to verify the effectiveness of multi-station and time-sharing measurement algorithm deduced on the basis of hybrid genetic algorithm.
By establishing the mathematical model of detecting the motion error of machine tool with multi-station and time-sharing measurement, the nonlinear redundant equations concerning base station calibration and measuring point determination can be obtained by large amount of measured data based on the GPS principle.
On the one hand, it is inexpensive to build, and on the other hand, it can easily be extended to multi-receiver stations and then obtain multi-baseline interferometric SAR images to rebuild accurate DEM of regions of interest.
