A crystal reference oscillator with improved g-sensitivity is realized through the use of an appropriately oriented single axis accelerometer. Components of acceleration normal to the plane of zero g-sensitivity of the oscillator are sensed by the accelerometer which returns a correction voltage to the electronic frequency control input of the oscillator. A model is developed that permits determination of accelerometer position relative to the oscillator without prior knowledge of crystal orientation. Author
