Example
Enter the following command to turn auto differential mode on:
$PASHS,RTC,AUT,Y
BAS: Set Receiver in Differential Base Station Mode
$PASHS,RTC,BAS,c1
This command sets the DG16 to operate as an RTCM differential base station,
where c1 designates the output port (A or B) for differential corrections. You can
view the current RTCM mode setting by entering the
$PASHQ,RTC command and
checking the MODE field.
Example
Enter the following command to set the receiver as an RTCM base station outputting
differential corrections from port B:
$PASHS,RTC,BAS,B
FMT: Differential Output Format
$PASHS,RTC,FMT,s1
This command sets the differential output format to either RTCM or RTCA. s1 is
either TCM or TCA.
RTCM and RTCA can also be used in place of TCM and TCA respectively.
IOD: Ephemeris Data Update Rate for RTCM Base Station
$PASHS,RTC,IOD,d
This command sets the time period before the RTCM base station switches to a
new issue of the ephemeris data (IODE) where d is the time between 0 and 90
seconds. The default is 30 seconds.
