Abstract
A strapdown measuring unit for measuring the angular velocities about the three axes of a flying body rotating relatively fast about its first axis is disclosed. The unit combines a Sagnac effect sensor for roll rate determination and two micro-mechanical acceleration sensors whose output, combined mathematically with the output of the Sagnac effect sensor, determines the angular velocity of the remaining two axes. The mathematical calculations are performed by a dedicated microprocessor which is integrated with the three sensors into a single small unit.
