The Physical Processes of the Errors Accumulation in Measurement Systems

Nowadays autonomous measurement systems are applied for the determination of the cinematic parameters of object motion. The principle of operation of such systems is based on the measurement of the object motion acceleration with the further integration of the accelerometer’s signal. These measurement systems are called inertial systems. Platform-less inertial systems are widely used for these purposes. Their specific property is an installation of the primary information sensors directly on the constructive elements of the object case. The inertial measurement systems have also a negative feature to accumulate constantly the errors of the system.
