More Book Details

Description of the Book:

The objective of this evaluation is to determine empirically the repeatable, non-repeatable and thermal error coefficients of the Collins/Rockwell and Singer Kearfott Multifunction gyro/accelerometer inertial reference units. The ultimate goal is to utilize these coefficients in error modeling algorithms in the effort of developing technology for cost efficient inertial sensors. The results of the evaluation support the postulate that the multifunction gyro/accelerometer concept, using appropriate error modeling coefficients is a technically sound method of improving performance characteristics and developing cost efficient instruments.
