Abstract

This paper deals with the in-flight alignment problem of the airborne strapdown inertial navigation system (SDINS) of unmanned aircraft. Design of alignment algorithms that increase alignment accuracy and decrease alignment duration is the purpose of the investigation. Initial alignment system pattern is proposed. Various integrated data processing modifications are analyzed. SDINS alignment simulation procedure is proposed. It allows to analyze developed integrated data processing modifications and to discover most efficient alignment system patterns.

Keywords:

strapdown inertial navigation system; Kalman filter; unmanned aircraft; initial alignment.
