Clock Estimation<br />
• Clock estimation uncertainties vs. clock stability<br />
– For stationary receiver with good satellite geometries<br />
– Under such ideal conditions, clock stability does not severely<br />
compromise location uncertainty<br />
– But it does compromise clock synchronization (frequency<br />
tracking)<br />
– Tends <strong>to</strong> corrupt the navigation solution<br />
