GLOBAL POSITIONING SYSTEM FUZE OSCILLATOR DESIGN SPECIFICATIONS FOR OSCILLATOR FOR DIGITAL GPS TRANSLATOR

ONE OF THE MOST CRITICAL COMPONENTS FOR ACCURATE NAVIGATION SOLUTION BY A GPS RECEIVER IS THE FREQUENCY TIME BASE PROVIDED BY THE OSCILLATOR. THE REQUIREMENTS FOR OSCILLATOR ARE EVEN MORE CRITICAL FOR A GPS DIGITAL TRANSLATOR SYSTEM. THE PHASE I STUDY WILL ESTABLISH PERFORMANCE REQUIREMENTS FOR THE OSCILLATOR FOR GPS TRANSLATOR BASED UPON THE REQUIRED SYSTEM ACCURACY GOALS. THE REQUIREMENTS WILL SPECIFY, AT A MINIMUM, OSCILLATOR PARAMETERS FOR FREQUENCY ACCURACY, SETTLING TIME, HYSTERESIS, PHASE NOISE, G-SENSITIVITY AND ENVIRONMENTAL CONDITIONS. THE OTHER DESIGN DRIVERS WILL BE SIZE, POWER, AND COST. THE SECOND PART OF THE STUDY WILL ADDRESS VARIOUS OSCILLATORS WHICH MAY BE SUITABLE FOR THE GPS TRANSLATOR APPLICATION. A REPORT DEFINING THE FEASIBILITY OF ACHIEVING REQUIREMENTS AND SUGGESTING ALTERNATE SOLUTIONS WHERE TECHNOLOGY IS NOT ABLE TO SUPPORT THE VERY HIGH SHOCK ENVIRONMENT FOR THE OSCILLATOR WILL BE PROVIDED.
