AbstractThe success of numerous weapons systems, now under active development, depends upon electronics capable of withstanding very high acceleration and mechanical shock. Most will use crystal oscillators. Applications include guided munitions, smartand penetrating weapons. For this program we are interested in the applications which incorporate on-board GPS receivers as part of the guidance system. The receiver requires a frequency source whose accuracy determines the time to acquire the firstsatellite. To meet the allowable thermally induced frequency shift this will be a TCXO - - a temperature-compensated crystal oscillator. Although the circuitry of a crystal oscillator is relatively shock inert, the conventional crystal resonators used areinherently susceptible to shock. To manufacture crystal oscillators shock-hardened up to 50,000 G there is a corresponding need for hardened resonators. PTI has been intimately involved over the past decade in the development of resonator shock-hardeningtechnology. Each technique developed to date has certain limitations, different for each. By combining techniques and adding new novel techniques we felt that inherent failure mechanisms could be eliminated. This first phase of this program demonstratedthat we can produce a much more rugged but still economical resonator to use in a high shock TCXO.
