Internal heated quartz resonator with low sensitivity to an accelerator

The paper describes results of development of the internal heated quartz resonator novel design. Such a resonator is built on composite heating of the crystal plate technique and possesses a unique compromise of high frequency stability with 15 s warm-up time, 4 mA heating current and less than 5/spl middot/10/sup -10/ 1/g acceleration sensitivity. The paper shows that the performances of the oscillator based on the IHR are very attractive for various global radionavigation and communication mobile systems.
