Paper presents the original computer-based method of the technical condition evaluation of the analog inertial navigation systems on the basis of the calculated inertial speed course analysis. There are presented the mathematical relationships describing the influence of the angular velocity and linear accelerations sensors errors (used in inertial navigation systems on board the military aircraft) with the relation to the discrepancies of the calculated pilot-navigational parameters (such as inertial speed components and navigational position coordinates). On the example of the Cardan navigation system IKW-8 (used on board the highly-maneuverable SU-22 aircraft) there are presented the inertial speed course measurement and analysis possibilities as well as the criteria of technical condition evaluation and determination of the tendency of its changes.
