DAM: Dual Automatic Mode

$PASHS,SBA,DAM
This command sets the DG16 to Dual Automatic mode.
This command sets the receiver to track SBAS satellites on Channel 1 and
Channel 2 and use this data in the navigation solution.
In Dual Automatic SBAS mode the DG16 automatically detects all available SBAS
signals and selects the best two satellites. Channel 1 tracks the best satellite
available, and Channel 2 tracks the second-best available satellite. In this mode,
the DG16 has no capability to continue to scan for other, better SBAS signals.
Therefore, once selected, the DG16 continues to track these two selected SBAS
satellites so long it is able. If the signal on one of the channels is lost, the DG16
scans the available frequencies to find another SBAS satellite.
The best SBAS satellite is determined based collectively on the satellite SNR, elevation angle,
continuity of signal reception, etc.
DAT: SBAS Output Message
$PASHS,SBA,DAT,c1,s1,[f1]
This command enables or disables the output of the SBAS messages on the
specified port. c1 is Port A, B, or C to where the messages output, s1 is ON or OFF,
and f1 is the optional frequency setting for the output ranging from 0.05 to 999
Differential Commands
