Aerospace Instrument-Making Annotation << Back A Control Algorithm with Enhanced Performance Characteristics for Navigation System Correction Kupriyanov A.O., Selezneva M.S., Pham Xuan Fang, Neusypin K.A. Over long periods of aircraft operation without correction of stationary navigation systems, errors in platform inertial navigation systems reach unacceptable levels and must be compensated for. Correction of navigation systems is implemented within their structure using control algorithms. Control algorithms are presented using linear stationary and non-stationary models, as well as one class of nonlinear systems represented by the SDC method. It is proposed to use error models of inertial navigation systems with improved controllability characteristics in the algorithms. A numerical criterion for the degree of controllability is selected to assess the quality of each navigation system error in the models under study. Keywords: navigation complex; inertial navigation system; control algorithm; correction in the system structure; error models, degree of controllability.
