A dynamic angular calibration system for broadband microradian inertial sensors
Abstract
Increased speed and accuracy requirements of inertially stabilized angular control systems have produced a measurement problem which has not been directly addressed by manufacturers of inertial test equipment. Development of dynamic angular sensors has had to parallel in-house equipment development programs. In the present paper, a calibration system is described which was developed to perform dynamic angular calibrations from below 0.5 Hz to over 500 Hz with an absolute accuracy of plus or minus 0.4% in amplitude and plus or minus 0.5 degrees in phase. Representative data taken with this system are presented. A sensor is described which has a demonstrated capability to measure broadband dynamic motion in the 0.1 arc second range.
