THREE-AXLE GYROSTABILIZER SELF-ORIENTING BY AZIMUTH Russian patent published in 1998 - IPC

FIELD: azimuthal orientation of mobile objects. SUBSTANCE: three gyros and two accelerometers which sensitivity axes are horizontal are put of stabilized platform and form stabilization and correction systems relative to two horizontal axes together with stabilization and correction amplifiers and stabilizing motors. Increased sensitivity unit of accelerometer and measurement unit are additionally inserted for orientation by azimuth. First unit incorporates comparator, electron key and current source electrically intercoupled. Input of comparator is connected to output of accelerometer and current source is linked to torque converter of accelerometer via key. Measurement unit includes second electron key, pulse generator, three reversible counters, digital-to-analog converter and summing amplifier. Second electron key is connected with controlling input to output of comparator and couples output of pulse generator and input of first reversible counter which output as well as outputs of two other counters are connected in series with first one and via digital-to-analog converter are connected to inputs of summing amplifier whose output is linked to torque converter of vertical gyro. EFFECT: decreased time for determination of direction of meridian. 2 dwg
