SWATH PATTERN IS OFFSET FROM THE SWATH
DIRECTION INDICATOR
• Implement measurements could be incorrect.
– Verify that measurements were entered as described at Physical
Layout screen.
– X measurements should be taken from the hitch pivot point to
where the seed is placed in the ground.
– Y coordinates are measured from implement center to the center of
each channel.
• Check row pattern setup at IntelliAg I/O screen.
• Check Physical Layout screen to verify layout is correct.
ROWS TURNING ON/OFF TOO EARLY OR LATE WHEN
ENTERING OR EXITING HEADLANDS
• Check Run In/Run Out overlap settings.
• Verify and check GPS calibration and run a new GPS calibration test, if
required.
• Verify that an additional delay value is not entered at the IntelliAg
Clutch Configuration screen.
• Verify implement measurements are correct.

• GPS has not been detected.
DATA LOSS AFTER POWER CYCLE
• Check power connections.
• Ensure ignition wire is conntected to switched source.
• Ensure console has continuous power.
GPS ACCURACY
RTK (1 inch pass-to-pass accuracy)
RTK is used with a reference receiver placed on a known reference point.
This receiver then communicates over a radio signal to the roving receiver
to determine position or navigation. RTK is a highly precise technique that
results in one inch year-to-year accuracy. RTK GPS requires two
specialized GPS receivers and two radios. One GPS receiver is set as a
base station with a 6 mile radius of the field you are working so it can send
the correction message to the roving receiver. Both receivers collect extra
data from the GPS satellites, known as L2 Band, that enables better
precision.
WAAS (6-8 inch accuracy) AND OMNISTAR HP (XP 3-5 inch
pass-to-pass accuracy) HP (2-4 inch pass-to-pass accuracy)
Waas and Omnistar services have many GPS receivers at known reference
locations that send the correction messages to control stations that uplink
the message to a geostationary satellite. The geostationary satellite (WAAS
or OmniSTAR) then sends the correction message to the GPS antenna on
the vehicle applying the correction.
