Super narrow pulse drive system substantially improves servo response Microcomputer high-speed arithmetic processing substantially improves gyro response High-resolution 12-bit A/D (Analog to Digital) accurately converts sensor output to a Digital Signal SMM (Silicon Micro Machining) micro-machining mechanical parts and systems right on a silicon chip and also low-back aeroform case improves vibration resistance and neutral characteristic AVCS (Angular Vector Control System) (same as Heading Hold) system requires a high-precision angular velocity detection function and extremely small output drift by using a new type of gyro sensor.
