Analysis Program for the evaluation and data reduction of the G ring laser observations

Ring lasers measure rotation rates. However, there are a number of corrections required to reduce the raw measurements of a local sensor to a global measurement quantity. Apart from backscatter corrections, a laser process induced nullshift bias has to be removed. Furthermore, one needs to correct for local orientation variations and several polar motion terms. This data is currently taken as input from the International Earth Rotation and Reference system service. 

The program is written in Labview version 2018
