Table 6.90 lists the RTCM commands.
AUT: Enable/Disable Auto Differential Mode
$PASHS,RTC,AUT,x
Turns auto differential mode on or off where x is Y (on) or N (off). When in auto-
differential mode the receiver generates raw positions automatically if differential
corrections are older than the maximum age, or are not available. Used only in
REMOTE mode.
When the receiver is in CPD (RTK) mode and fast CPD mode is off ($PASHS,CPD,FST,OFF), then
the rover receiver does not generates any positions if data from the base station is unavailable.
Example: Turn auto differential mode on
$PASHS,RTC,AUT,Y<Enter>
