Example
Enter the following command to set the receiver as an RTCM base station outputting
differential corrections from port B:
$PASHS,RTC,BAS,B
IOD: Ephemeris Data Update Rate for RTCM Base Station
$PASHS,RTC,IOD,d
This command allows you to set 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.
This message is applicable to receivers in RTCM BASE mode only. A base receiver
continues to transmit corrections on the old ephemeris in the navigation solution
until it receives RTCM corrections on the new IODE.
$PASHQ,RTC,IOD,[x]
This command allows you to query for the time period for when the RTCM base
station switches to a new issue of the ephemeris data, where x is the optional port
designator for the output of the response. If a port is not specified, the receiver
sends the response to the current port.
The response is in the format:
$PASHR,RTC,IOD,d*cc
where d is the set IOD switch period in seconds.
MAX: Maximum Age Threshold for Differential Corrections
$PASHS,RTC,MAX,d1
This command allows you to set the maximum age for incoming RTCM differential
corrections, where d1 is any number between 1 and 1199. The receiver ignores
incoming corrections whose age exceeds the maximum age setting. The default
value is 60. The maximum age setting applies to remote differential stations only.
You can view the current maximum age setting by entering the query command
$PASHQ,RTC and checking the MAX field.
Enter the following command to set the maximum age to 30 seconds:
$PASHS,RTC,MAX,30
DEFAULT SETTING
RTC,MAX— 60
