GLONASS IN THE ARCTIC: RESULTS OF A COMPREHENSIVE STUDY OF THE NAVIGATION SITUATION DURING THE TRANSITION ON THE NORTHERN SEA ROUTE IN AUGUST-SEPTEMBER 2011

The paper discusses the main results of the experiments of the navigation situation studies in the high northern latitudes during the transition of the border patrol vessel from Murmansk to Nevelsk  (Sakhalin Island) in 2011.
The main goals of the experiment: testing of domestic and foreign consumer navigation equipment (CNE) samples, including usage of differential navigation mode; estimating the accuracy of the formation of the vessel movement trajectory on the basis of a posterior data processing of various dual frequency GLONASS / GPS receivers; evaluation of the real navigation conditions during the transition; development of the data exchange technology between the ship and the IAC CTNS.
The experiment involved more than ten samples of the navigation equipment. Test samples of navigation equipment operated in different modes of navigation: based on Global Navigation Satellite Systems (GNSS), GLONASS, GPS and in a joint mode GLONASS+GPS, and also using differential mode navigation definitions.
The results of the estimation of the positioning accuracy of the CNE samples in their various modes of operation and the results of the quality assessment of the navigation situation using GNSS GLONASS and GPS are presented.
