The operation of technical processes requires increasingly advanced supervision and fault diagnostics
to improve reliability and safety. This paper gives an introduction to the field of fault detection and diagnostics and
has short methods classification. Growth of complexity and functional importance of inertial navigation systems
leads to high losses at the equipment refusals. The paper is devoted to the INS diagnostics system development,
allowing identifying the cause of malfunction. The practical realization of this system concerns a software
package, performing a set of multidimensional information analysis. The project consists of three parts:
subsystem for analyzing, subsystem for data collection and universal interface for open architecture realization.
For a diagnostics improving in small analyzing samples new approaches based on pattern recognition algorithms
voting and taking into account correlations between target and input parameters will be applied. The system now
is at the development stage.
