Footnotes:
1. Accuracy and reliability may be subject to anomalies such as multi-path,obstructions, interference, satellite geometry and atmospheric
2. May be affected by atmospheric conditions, signal multipath, obstructions andsatellite geometry.
3. May be affected by atmospheric conditions, signal multipath, and satellite
geometry. Initialization reliability is continuously monitored to ensure highestquality.
