The Changing Emphasis and Future Trends in Navigational Gyros 650586

Although prime requirements for inertial sensors historically have been performance and reliability, there is now sharply increased emphasis on cost factors. As a result, new concepts have been advanced at rapid pace. These are discussed briefly to point out development status and capability. Gas bearing and ESG concepts are discussed in further detail with respect to performance capability, design integrity, and cost factors. Comparisons are made in these areas to qualify these two gyro types as low-cost navigational gyro candidates.
