Summary
146 Max talks about the seven different kinds of minimums used on WAAS-based GPS Approaches. These include LPV, LNAV/VNAV, LNAV, LP, LNAV+V, LP+V, and circling minimums. To measure GPS errors, the FAA has installed GPS receivers at 38 locations in North America. Error information from these sites is uplinked to two new geosynchronous satellites that retransmit it to WAAS-capable receivers.
