ABSTRACT:
A system providing economical redundant strap-down inertial measurement capability in a space navigation system. By appropriate orientation of two-degree-of-freedom dry tuned rotor gyros, the system is able to achieve complete redundancy utilizing only three gyro units. With this orientation, both orthogonal and skewed rate data are available. Not only are the necessary computations materially simplified, but this system also provides the necessary conditions for failure detection and isolation.
