Reference of Icons
GPS Status
The current source and status of DGPS signal is displayed in the upper, left corner of the Home screen.
Note:
The standard GPS shield will be displayed if the Envizio Pro or Envizio Pro II field computer
cannot determine the type of corrections being sent from the DGPS receiver.
The status icon on the Home screen will display:
• Green if the status of GPS is okay.
• Yellow if an error condition has been encountered.
• Red if GPS is non-functional. Make sure the DGPS antenna cable connections are secure and the antenna
has a clear, 360° view of the sky.
RTK Fixed and Float Modes
When using an RTK correction source with the internal dual frequency GPS receiver, the GPS status indicator
may be used to determine whether the receiver is operating in RTK fixed or float modes. The RTK shield will
display:
• Green to indicate a fixed RTK position. This mode indicates that the receiver has a full RTK position fix and
is providing sub-inch corrections.
The GPS Health screen will display a value of 4 for the differential mode when operating in RTK fixed mode.
• Yellow to indicate that the receiver is operating in RTK float mode. This mode indicates that the receiver is
not able to provide a full RTK position lock due to the distance from the base station, visibility of the sky,
time of day or interference around the base station location. In the float mode, the receiver is still providing
a course RTK correction signal, but accuracy of the receiver may not be at a sub-inch level.
The GPS Health screen will display a value of 5 for the differential mode when operating in RTK float mode.
Direction of Travel
The last direction of travel detected by the field computer is displayed on the screen when setting
up a job on the field computer and may also be found on the GPS Health screen by selecting the
GPS Status icon.
If the direction of travel displays incorrectly during a field application, touch the direction of travel
icon to manually toggle the course over ground.
