SmarTrax HDOP Limit
- Horizontal Dilution of Precision (HDOP) is an indicator of the quality of the GPS signal.
A high HDOP indicates that not enough satellites are distributed evenly throughout the sky, diminishing the
accuracy of the guidance system. The number displayed is the maximum number SmarTrax MD will allow to
run. Raising this number may degrade system performance.
NOTE:
The default SmarTrax HDOP limit is 2.5. Increasing the HDOP limit may degrade SmarTrax
performance. Decreasing the HDOP limit may cause SmarTrax MD to disengage more often.
•
SmarTrax GPS Baud
- The rate the system uses to communicate with the GPS receiver. This value is typically set
to 19200, but it can be changed to match the baud rate of receivers that cannot be easily changed to 19200.
NOTE:
With the 600S GPS Receiver and SmarTrax MD software version 7.6 and newer, the GPS baud will
automatically change to 115200 to allow communication with the 600S for configuration or changing
settings.
•
SmarTrax GPS Frequency
- The GGA message update frequency in hertz (Hz).
•
Minimum GPS Correction
- This setting is used to select the correction source providing the minimum
accuracy allowable for SmarTrax operation. This selection may be used to prevent the SmarTrax system from
sudden course changes if the desired correction source is lost. For example, selecting RTK for this feature will
disengage SmarTrax if RTK corrections are lost.
