Abstract:
The paper presents procedures and results of studies on error of the radio-inertial integrated navigation system that performs optimal data fusion from autonomous and non-autonomous navigation data channels using optimal Kalman filtering. It has been shown that in case the optimal data fusion error and non-autonomous navigation data channel error are roughly equal, optimal data fusion using Kalman filtering becomes meaningless, which makes it possible to construct a radio-inertial integrated navigation system according to the relaying scheme without having to sacrifice navigation information accuracy. The results of the research can be used in the development and upgrade of radio-inertial integrated navigation systems, as well as GNSS user equipment jammers.
