Trimble R6 and R7 GPS/R8 GNSS Receiver Operation
PTNL,GGK_SYNC
Time, Synchronized Position, Position Type, DOP
The PTNL,GGK_SYNC message has the same format as the PTNL,GGK message, but
outputs Synchronized 1 Hz positions even in Low Latency mode. An example of the
PTNL,GGK_SYNC message string is shown below. Tabl e A.8 describes the message
fields.
$PTNL,GGK_SYNC,172814.00,071296,
3723.46587704,N,12202.26957864,W,
3,06,1.7,EHT-6.777,M*48
Note – The PTNL,GGK_SYNC message is longer than the NMEA-0183 standard of 80
characters.
