Web4 visible satellites are not enough to provide integrity, 5 visible satellites: if an anomaly is detected, the measurement from that specific satellite is discarded and therefore only 4 satellites are left. WebWAAS stands for Wide Area Augmentation System. Even though the FAA created it, many GPS receivers now use it to formulate more accurate positions. WAAS uses a separate network of ground stations and satellites to calculate any errors in the existing GPS network and help your receiver correct them.
