Applications of Microfabricated Atomic Clocks<br />
• Size (1 cm 3 )<br />
• Power (30 mW)<br />
Integration in portable,<br />
battery-operated devices<br />
• Precise timing: higher-per<strong>for</strong>mance, more reliable operation<br />
Key application areas:<br />
• Global positioning and navigation (GPS)<br />
• Faster acquisition time<br />
• More precise altitude determination<br />
• Direct P(Y)/M code acquisition → anti-jam capability<br />
• <strong>Position</strong> solution with < 4 satellites visible<br />
• Wireless communications, network synchronization<br />
• Fewer dropped cell phone calls<br />
• Avoidance of data accumulation<br />
• Data logging, seismology, remote sensors…<br />
• Others we don’t even know about
