An NSI-2000MTG Integrated Navigation System

摘要

The paper presents the results of developing an integrated INS/GNSS navigation system NSI-2000MTG with enhanced availability of satellite measurements. A general concept of the system is given; the main operation modes and the software architecture are described. The problems of filtering and correction are considered for the case of irregular entry of measurements of different compositions; algorithmic solutions to these problems are offered. The results of mobile tests, flight testing of the system software, and simulation tests are discussed.
