Abstract
Fiber optic gyroscope (FOG) technology has reached fruition as a marketable instrument. Bell Aerospace Textron and Standard Electrik Lorenz offer a line of FOGs from standard to enhanced performance designs. Operation of these FOGs is based on an interchangeable and reliable interferometric optics unit with electronics tailored to meet customer needs. Attitude Reference and Heading stabilization and rate applications are the market targets for this line of gyroscopes. They are marketed with the competitive edge of reduced life cycle and maintenance costs. We will show how the core optics unit is reliably made and applicable to the range of applications being considered. Specifically the ability to use the same set of optics for various design will be detailed along with the digital method of retrieving sensor data. Outputs are available as either rate or angle and analog or digital allowing implementation by customers in existing equipment without large accommodating changes in the surrounding system. Performance specifications will be presented for the standard and enhanced FOGs and test data from Bell Aerospace Textron Standard Electrik Lorenz and National Laboratories will be presented verifying the operational performance capabilities of the open loop version of the FOG. Extensive testing of the FOG has been conducted over a large environmental regime including temperature variations magnetic field intensities vibration and shock. Specific drift scale factor misalignment angle and unique vibration tests will be described and test
