Abstract
An inertial measurement system for determining the attitude and rate of change of attitude of a vehicle such as an aircraft is disclosed. Redundancy of the inertial measurement system may be accomplished by utilizing a global positioning system having three receivers and a set of antennas strategically disposed on the vehicle. The global positioning system having receivers may be utilized for accomplished failure detection and isolation of the inertial measurement system rather than providing a redundant inertial measurement system. Failure detection of the IMUs may be accomplished with only dual antenna/receiver configuration.
