Abstract :
A high shock (50 kG) survivable precision frequency source for use in miniature GPS receivers has been developed, enabling fast satellite acquisition in advanced gun-launched "smart" projectiles. The TCXO (temperature-compensated crystal oscillator) has demonstrated survivability through in-house gas-gun high shock testing. The critical element, the quartz crystal, has been shock-hardened, and the circuitry has been miniaturized using an ASIC.
