103 – Query/Rate Control
This command is used to control the output of standard NMEA messages GGA,
GLL, GSA, GSV, RMC, and VTG. Using this command message, standard
NMEA messages may be polled once, or setup for periodic output. Checksums
may also be enabled or disabled depending on the needs of the receiving
program. NMEA message settings are saved in battery-backed memory for each
entry when the message is accepted.
The table below contains the values for the following example:
1. Query the GGA message with checksum enabled
$PSRF10 3 ,00,01,00,01*25
104 – LLANavigationInitialization
This command was used to initialize the receiver with the current position (in
lattitude, longitude and altitude coordinates), clock offset, and time, enabling a
faster fix. Increased receiver sensitivity and the removal of Selective Availability
(SA) have made this unneccessary. The command is retained for its ability to
reset the module, but the initialization fields are no longer supported.
The table below contains the values for the following example:
$PSRF104,0,0,0,96000,0,0,12,4*1A
2. Enable VTG message for a 1 Hz constant output with checksum enabled
$PSRF10 3 ,05,00,01,01*20
3 . Disable VTG message
$PSRF10 3 ,05,00,00,01*21
