52 Ag Leader Integra and Versa Firmware Version 4.3 / Edge Firmware Version 5.1
General
The General screen displays the status of a number of
operational parameters GPS Mode parameter displays
the current GPS mode of the receiver.
• PDOP (Positional Dilution of Precision) is a measure of the strength of the satellite configuration. When
visible GPS satellites are close together in the sky, the geometry is weak and the DOP value is high;
when far apart, the geometry is strong and the DOP value is low. Thus a low DOP value represents a
better GPS positional accuracy.
• Heading displays the heading of the vehicle in degrees.
- You will not be able to autocalibrate or autosteer your vehicle before the Heading item displays a value.
• Height displays the vehicle’s altitude above sea level.
• # of satellites displays the number of satellites being tracked by the receiver.
• Vehicle Position displays the latitude and longitude of the vehicle.
Satellite Tracking
The Satellite Tracking screen displays the status of the
tracked satellites. Use the left and right arrows to
select a PRN and view the information specific to that
PRN
The screen displays the signal to noise ratio (SNR) for
each satellites being tracked for L1, L2 on the left
antenna and L1 for the right antenna. The SNR is also
depicted in a bar graph format. An overview of eight
satellites can be displayed.
• Elevation: the elevation of the satellite above the horizon.
• Signal Strength: The strength of the signal for the selected satellite.
• Antenna A display: The light blue bar is L1 signal strength, the dark blue bar is L2 signal strength.
• Antenna B display: The light green bar is L1 signal strength, the dark green bar is L2 signal strength.
• Base Station display: The light red bar is L1 signal strength, and the dark red bar is L2 signal strength.
Note: The Signal View window shows the number of satellites being tracked and their signal
strength. Signal strength below 15 is marginal. A signal strength above 40 is good. It is necessary
to track more than five satellites and it is preferable to track eight or more satellites.
