Note:  If Implement Steering is available, verify the Implement Steering GPS in addition to the machine’s GPS.

To access GPS information:

1. Select Settings on the bottom left of the Home screen. The Settings Menu will open.
2. Select GPS on the Settings menu.
3. Select the DIFF tab to view and select GPS Differential Differential Global Positioning System is an enhancement to standard GNSS/GPS messages to provide better position accuracy. Setup information such as available differential Differential Global Positioning System is an enhancement to standard GNSS/GPS messages to provide better position accuracy. Type and PRN Pseudo-Random Number.

   Note:  It is recommended to keep differential Differential Global Positioning System is an enhancement to standard GNSS/GPS messages to provide better position accuracy. settings set to Auto unless directed otherwise.

4. Select the PORT A tab to view and edit information on the GPS: Port A Configuration screen. If desired, select additional port tabs to view and edit GPS information for those ports. In some cases Port may be referred to as COM.

   

   Note:  Port A is not configurable.

5. Select PORT B tab to configure a generic GPS receiver. Generic GPS NMEA National Marine Electronics Association Out must have the following settings:

   • GGA at 10hz

   • VTG at 10hz

   • ZDA at 0.2hz

   Optionally, the follow settings are allowed:

   • GSA at 0.2hz

   • GST at 0.2hz

   • GSV at 0.2hz

   A baudrate of 115200 is highly recommended.

   Note:  The radar out is always functioning when a GPS receiver is detected, and pulses at 45 Hz per 1 mph or ~27.5 Hz per 1 kmh or ~100 Hz per meter.

6. Select the INFORMATION tab to view information on the number of satellites visible, Elevation, GPS Quality, HDOP Horizontal Dilution of Precision, Diff Age, Diff ID, Messages, and Differential Differential Global Positioning System is an enhancement to standard GNSS/GPS messages to provide better position accuracy. type.

   Note:  The image below shows an example of what a GPS satellite array may look like above an implement. The blue dots are GPS satellites current being used for corrections. The GPS satellites that are grayed out indicate satellites not being used for correction.

   

7. Select Accept to save the displayed settings and return to the Settings menu.

View GPS Solution Information

To view solution information supplied by the GPS:

1. Select the Settings icon on the bottom right of the screen. The Settings Menu will open.

2. Locate and select the GPS module. The GPS Global Settings prompt will display.

3. Select the GPS Diagnostics button to the right of the desired GPS receiver. The GPS Solution Information page will be displayed.

   

4. The following information about the current GPS solution is displayed on this screen:

   Latitude/Longitude

   The current geographic coordinates of the ROS device.

   Elevation

   The current GPS elevation above sea level.

   Satellites

   Displays the number of satellites currently used in the position solution.

   Differential ID

   Depending upon the correction source used, this value will display the differential Differential Global Positioning System is an enhancement to standard GNSS/GPS messages to provide better position accuracy. source identification such as the differential Differential Global Positioning System is an enhancement to standard GNSS/GPS messages to provide better position accuracy. satellite PRN Pseudo-Random Number, a base station ID, etc. Some correction sources will not populate this field.

   Differential Age

   This value is the age of the last differential Differential Global Positioning System is an enhancement to standard GNSS/GPS messages to provide better position accuracy. update. The differential Differential Global Positioning System is an enhancement to standard GNSS/GPS messages to provide better position accuracy. age should not rise above a few seconds to ensure accurate position corrections during field operations depending on correction type.

   HDOP

   Horizontal Dilution of Precision (HDOP Horizontal Dilution of Precision) is a value indicating the geometry of the satellites used in the position solution. Lower values indicate better positioning of the used satellites.

   GGA Quality

   Displays the current differential Differential Global Positioning System is an enhancement to standard GNSS/GPS messages to provide better position accuracy. fix status. This value will display:

   • ‘0’ or ‘1’ if no differential Differential Global Positioning System is an enhancement to standard GNSS/GPS messages to provide better position accuracy. corrections are being received, single solution.

   • ‘2’ when the DGPS Differential Global Positioning System is an enhancement to standard GNSS/GPS messages to provide better position accuracy. receiver has locked on to a differential Differential Global Positioning System is an enhancement to standard GNSS/GPS messages to provide better position accuracy. source (SBAS or converging with GS/OmniSTAR corrections).

   • ‘4’ for RTK Real-time Kinematic fixed mode for fine GPS course correction mode.

   • ‘5’ for fixed GS or OmniSTAR XP/HP correction modes or RTK Real-time Kinematic float mode.

   UTC Time and Date

   Universal coordinated time and date information is displayed in these fields (Greenwich Mean Time).

   Messages

   Displays what NMEA National Marine Electronics Association messages are being received by ROS and the frequency at which they are being received.
