RTC: Query RTCM Operating Parameters and Status
$PASHQ,RTC,[c1]
This command queries for differential parameter settings and status, where c1 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 message has a free-form Ashtech format. Like the PAR response
message, the RTC response message does not have a header or message
identifier as shown in the following example:
STATUS:
SYNC: TYPE:00 STID:0000 STHE:0
AGE:+999 QA:000.00% OFFSET:00
SETUP:

Table 9.3 describes the items in the RTC response message:
Table 9.3. RTC Response Format
Parameter Description Range
STATUS This subsection of the RTC response contains status information
related to the performance of the remote differential station, such
as message synchronization status, the type of message being
received, the ID number of base station broadcasting the
corrections, etc. SYNC, TYPE, STID, STHE, AGE, QA, and
OFFSET fall into this subsection.
SYNC: An asterisk (*) appearing in this field indicates that synchronization
between base and remote has been established. Synchronization
has not been established if this field is blank. This field applies to
remote differential mode only. *
TYPE: Indicates RTCM message type received by the remote station. 1, 2, 3, 6, 9, 16
STID: The ID number of the differential base station. This ID number is
received from the base station. 0000 to 1023
STHE: This code number indicates the health of the base station. 0 to 7
