Feasibility Study of Performing System Calibration in an Operate Mode.

摘要

The availability of a system can be upgraded if the usual downtime allocated for performing calibration tasks is reduced or eliminated. The objective of this paper is to study the feasibility of performing the calibration of system parameters while the system is in an operate mode. To this end, a calibration technique exhibiting this feature was developed and studied for a marine inertial navigation system. The errors introduced by the calibration technique were examined and problematic areas were outlined. Although the report is directed specifically towards the calibration of certain parameters of a particular system, the ideas and concepts presented in the development of the report's calibration technique should be applicable to other system for the elimination of all or some of their calibration downtime. The formulation of a similar type of calibration procedure is especially desirable for systems whose unavailability at a time of critical need could result in a catastrophic loss of men, material and tactical advantage.
