4.Select Status SBAS from the Window menu to see the number of valid SBAS messages that are being decoded for a specific SV number since the last power-up. When the Valid Messages count is not incrementing, it means that either the receiver is not tracking any SBAS satellites, or it is unable to demodulate the SBAS bit stream.

Refer to the L1 GPS Firmware Reference Manual for more details on individual SBAS messages that use the SBAS corrections and for an appendix on SBAS Positioning that includes an explanation of dynamic modes. Refer also to Message ID# 30, Receiver Configuration in the same manual.
