Table 4.79: RTC Message Structure
Item Description
STATUS Asterisk (*) denotes sync to last received RTCM message between base and remote
stations (remote only).
TYPE RTCM message type being sent (base) or received (remote). Types 1,2,3,6,16,18/
19
STID Station identification received from the base station. 4 characters, 0 through 1023
STHE Station health received from the base station. See $PASHS,STH for details.
AGE In base mode, displays the elapsed time between the beginning of transmission of
message types 1, 9, 18/19. In remote mode, displays the age of the received
messages in seconds.
QA Displays the communication quality factor betwee base and remote. Defined as 100
x number of good measurements, divided by total number of messages. Remote only.
OFFSET The number of bits from the beginning of the RTCM byte, in case of bit slippage.
MODE RTCM mode. BAS (base), REM (remote) or OFF (default).
PORT Communication port, A or B (default is A).
AUT Automatic differential mode, ON or OFF (default).
SPD RTCM bit rate. Burst mode transmits RTCM messages at the current configured serial
port baud rate. Rates are 0 (burst mode), 25, 50, 100, 110, 150, 200, 250, 300,
1500.
STI User-assigned station ID. 4 characters, 0 through 1023
STH Station health. See STHE.
MAX Specifies the maximum age, in seconds, required for a message to be used (remote
only). Range is 0 through 999, 60 is default.
QAF Sets the criteria to be applied when evaluating the quality of communication between
base and remote. Remote only. Range is 0 through 999, default is 100.
SEQ Check for sequential received message number for the message to be accepted (base
only. N = no (default), Y = yes.
TYP RTCM message type that the sensor can generate (base only. Type 1, 2, 3, 6, 16,
18/19.
EOT End of transmission data. CRLF (default), CR, or NONE
FRQ RTCM message send frequency. The period is in seconds for types 1 and 18/19, and
minutes for all other types. 99 = continuous, 00 = disabled. Default is 1 for type 1,
OFF for type 6, and 1 for 18/19.
MSG For base mode, contains the message, up to 90 characters, that is sent from base to
remote when message type 16 is enabled. In remote mode, displays the message, up
to 90 characters, that is received from base.
