Abstract

We present the hardware and software implementation of the information technologies for the GNSS service of the Russian-Cuban co-located geodetic station. The service is equipped with geodetic and meteorological instruments with data acquisition and transmission systems and allows to conduct high-precision observations of the GPS and GLONASS global navigation satellite systems (GNSS) as well as meteorological measurements. The coordinates of the station are refined while processing GNSS observations and according to the change in coordinates, the movement of Cuban tectonic plates is estimated. Information technologies of the GNSS service is one of the key elements required for conducting regular automated geodetic and meteorological measurements. Information technologies is a group of computing and networking equipment that provides preliminary processing and transfer of observations to the data processing centre at the Institute of Applied Astronomy in St. Petersburg. It also allows the remote monitoring, control, and maintenance of GNSS service scientific instruments.
