General Direction To Target Indicator; Dgps Receiver Setup - Raven RGL 600 Operation Manual

GENERAL DIRECTION TO TARGET INDICATOR

A General Direction to Target Indication is displayed on an alphanumeric display digit to show
the direction towards various targets. An example is the left most digit of the guidance offset
error display when the offset error is less than 100. From the perspective of the operator, this
is a general pointer to the swath line (or other target) that is in control.

DGPS RECEIVER SETUP

The Smartbar uses position and course information provided by certain messages from your
GPS receiver. Referring to the GPS receiver documentation, configure it to output $GPGGA
messages and $GPVTG messages. Alternatively, you could configure your GPS receiver to
output only $GPRMC messages.
Note that your GPS receiver documentation may drop '$GP' from the message names, and
refer to them as GGA, VTG, and RMC.
Set the GPS receiver communications BAUD rate and message output rate as high as
possible. The Smartbar works with standard BAUD rates from 4800 to 38400 and message
output rates up to 10 position solutions per second (hertz). The Smartbar responds best when
the GPS receiver communications is at 38400 BAUD and the message output rate is at 10
hertz.
If the message output rate is 10 hertz, the GPS receiver BAUD rate must be at least 19200.
If the message output rate is 5 hertz, the GPS receiver BAUD rate must be at least 9600. A
BAUD rate of 4800 is only practical if the message output rate is 1 hertz.
