If changed parameter values are saved by the $PASHS,SAV,Y set command, after the next power-
up, the response to the $PASHQ,RTC query command will display the saved quantities instead of the
defaults. $PASHS,RST always reinstates the defaults.
SEQ: Check Sequence Number
$PASHS,RTC,SEQ,c
Checks sequence number of received messages and, if sequential, accept corrections;
if not, don’t use correction, where c is Y (check) or N (do not check). Default is N.
Used only in REMOTE mode. Valid only at beginning of differential operation.
After two sequential RTCM corrections have been received, differential operation
begins.
Example: Check sequence number
$PASHS,RTC,SEQ,Y<Enter>
FRQ Indicates the output period for message types 1, 2, 3, 9, 16, 31, 32, 34, and 36. A 0
indicates message disabled, a 99 indicates continuous output, and any other number
specifies the number of seconds between transmissions for message types 1, 9, 31, and
34, and the number of minutes between transmissions for all other messages. Default
for message types 1 and 31 is 99, for types 6 and 6G is OFF, and for all other messages
is 00.
BASE For base mode, displays the antenna position of the base station in latitude, longitude,
altitude above reference ellipsoid, and reference coordinates to use when computing
corrections. Antenna position is entered with commands POS.
MSG For base mode, contains the text message, up to 90 characters, that is sent from the base
to the remote when message type 16 is enabled. In REMOTE mode, displays the text
message, up to 90 characters, that is received from the base.
MSG(GLO) For base mode, contains the text message, up to 90 characters, that is sent from the base
to the remote when message type 36 is enabled. In REMOTE mode, displays the text
message, up to 90 characters, that is received from the base.
