Decimal digits in GGA:
Sets the number of decimal digits in GGA output.
Decimal Digits in RMC and GLL
Sets the number of decimal digits in RMC and GLL output.
NMEA Talker ID: (Default is “P”)
Assign a unique talker ID to these non-constellation message types. This NMEA talker ID
relates to the following message types; RMC, GGA, VTG, GST, GLL, and ZDA.
Note: Constellation related messages are automatically assigned on selection of
constellation type.
•
GP” indicates the GPS constellation
•
“GL” indicates the GLONASS constellation
•
“GN” indicates satellites for all constellations
Delay from Fix to Start of Output:
Message output can be delayed related to time of the current fix. This establishes a
known offset from the receipt of the NMEA message to the time stamp within the
message; thus permitting reliable time transfer. This feature only applies to the high
priority message list 3.
If the start of a NMEA out message is being used for timing purposes the “fix rate”
should be set to 1 second and message list 3 used.
For >5Hz fix rate operation this parameter should be set to zero.
GLONASS satellite Format:
(default ID is based on slot)
Selects satellite ID based on “frequency” or “slot” (as reported in almanac and
ephemeris data).
NMEA output
:
The TW5340 will output messages that are specified in up to 3 lists. Each of the
message lists can be output at a different rates.
