WAAS-SBAS is enabled by issuing Message ID 133, (MID 133) is supported in One Socket
Protocol (Formerly Sirf Binary Protocol mode), and then the accuracy improves to 300 cm ~
100 cm with it enabled, depending on Open Sky Conditions (Multi-Path interference). With
MID 133 not enabled, the accuracy is near 1500cm.
Some examples of these are (GPS Aided GEO Augmented Navigation) GAGAN
How do we enable WAAS-SBAS on the W2SG0084i?
