Connectivity in speed and GPS

Discover common issues and fixes about connectivity related to speed and GPS.

Updated June 29, 2020

Speed

The top right-hand corner of the home screen displays the current speed of the tractor. The bars under the speed source icon indicate signal strength.

Icon colors indicate:

  • White indicates speed source connectivity is good.
  • Yellow indicates communication is lost momentarily, there are errors in the signal, or the GPS signal is lost.
  • Red indicates the speed source is unusable.

There are three different icons that can be displayed:

  1. GPS receiver icon - This indicates the speed source is coming from the GPS system.
  2. Tractor or radar icon - This indicates the speed source is coming from the radar system.
  3. A capital “R” inside of a box - This indicates the tractor is moving in reverse.

GPS

Navigate to GPS communication by pressing the speed button in the top right-hand corner of the home screen.

For best GPS results:

  • Set the Baud Rate to 19200 or 38400 in the system outputting the GPS.
  • The communication quality should be as close to 100% as possible.
  • There should be at least three satellites within view.
  • The HDOP should be between 0 – 2.
  • Set NMEA messages GGA, RMC (or ZDA), and VTG at 5 Hz in the system outputting the GPS. Additional NMEA messages may degrade the GPS information with too much information.

GPS communication

GPS logs may be enabled at the bottom of the page if requested by Precision Planting Support. Press the “Reacquire GPS” button at the bottom of the screen to try to reacquire the GPS signal.

GPS corrections

Configure how the system handles the GPS signal.

Do not change any of the GPS correction settings unless instructed to do so by a Dealer or Precision Planting Product Support.

Bad GPS correction Change between calculated and GPS speed. Use calculated for lower-grade GPS systems.

Heading mode Change between calculated and GPS. Use calculated for lower-grade GPS systems.

Correction level Change from normal to high. High correction level will raise the minimum GPS quality percentage for mapping.

Primary packet Switch between GGA and RMC for the primary NMEA packet.

GPS nudge

Use to move the map data in situations where GPS shift has occurred. Use the +1 buttons to nudge the map in that direction.
