GPHDTDUALANTENNA

Synchronous NMEA heading log

Platform: OEM7720, PwrPak7D, PwrPak7D-E1, PwrPak7D-E2, CPT7

This log contains actual vessel heading in degrees True (from True North). It provides the same information as the GPHDT log, but with synchronous output.

You must have an ALIGN capable, dual antenna receiver to use this log.

If the NMEATALKER command is set to AUTO, the talker (the first 2 characters after the $ sign in the log header) is set to GP (GPS satellites only), GL (GLONASS satellites only), GA (Galileo satellites only), GQ (for QZSS satellites only), GB/BD (for BeiDou satellites only) or GN (satellites from multiple systems).

Message ID: 2045

Log Type: Synch

Recommended Input:

Example 1 (GPS only):

$GPHDT,75.5664,T*36

Example 2 (Combined GPS and GLONASS):

$GNHDT,75.5554,T*45
