Self-contained location detectors with fiber optic gyroscope and its application to the car location system

A location detector with a fiber-optic gyroscope (FOG) and its application to a patrol car location system are described. Several methods of handling the output signal of the FOG as well as other kinds of techniques have been developed. These technologies are also applied to navigation systems used in consumer passenger vehicles. It is believed that an advanced police information system could be constructed by integrating this system with other systems.<
