Application of an Inertial Positioning System for Estimation of Coordinates and Orientation of Optical Modules of the Baikal-GVD Deep Underwater Neutrino Telescope

AbstraktAbstract

The new generation neutrino telescope Baikal-GVD is under deployment in Lake Baikal. The telescope registers Cherenkov radiation resulting from the interaction of neutrinos with the water environment of the lake, using the spatial structure of optical modules – photodetectors. To determine the direction to the neutrino source, it is necessary to know the coordinates of each module at the time the event was recorded. The article describes the design and operating principle of the inertial positioning system, which serves to determine the spatial position of modules in the aquatic environment, and presents the first results of its operation.
