RTC: Query RTCM Operating Parameters and Status
$PASHQ,RTC,[c1]
This command allows you to query 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 proprietary 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:+000 QA:100.0% OFFSET:00
SETUP:
MODE:OFF PORT:A AUT:N
SPD: 0300 STI:0000 STH:0
MAX: 0060 QAF:100 SEQ:N
TYP:01 02 03 06 09 16
FRQ:99 00 00 ON 00 00
BASE: LAT:0000.0000,N LON:00000.00000,W ALT:+00000.00
MSG:
THIS IS A TEST MESSAGE
Table 4.118 describes the items in the RTC response message:
Table 4.118. 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 type of message being 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 - 1023
STHE: This code number indicates the health of the base station 0 - 7
