After the channel and startup accuracy have been selected, press the Blue Right Arrow button shown in Figure 2-6 to continue
to the next step.
Precision Preference Selection
GeoSteer is designed to allow the user flexibility in selecting the accuracy level the system operates at. Depending on the
GeoSteer Feature Codes that have been unlocked, the geographic location, OmniSTAR Demodulator that may be installed, the
user can choose from Autonomous Pass-to-Pass all the way up to RTK. In RTK and OmniSTAR modes, the system also allows
the accuracy to “Flex” back to WAAS/EGNOS or Autonomous Pass-to-Pass when the RTK or OmniSTAR signal is lost for a
short time. To choose the accuracy level that GeoSteer will operate at, press the Change Mode button shown in Figure 2-8.
Figure 2-8 Set Precision Preference
The list of Available Precision Settings will display. This list will depend on which features have been unlocked, whether the
system detects an OmniSTAR Demodulator, and the geographic location the system believes it is located. Not all options will
be available to all users. Select the Precision Setting that the system will operate with and then press the Green Check button to
save that selection. Press the Red X button to cancel.
Figure 2-9 Available Precision Settings
Each of the selections has specific accuracy levels and operational requirements. An explanation of each setting is provided
below:
Note: “Flex” is a term that denotes the system switching from one accuracy level to another when a correction source is lost. In
most cases, this happens when the RTK data link between the Base Station and the GeoSteer is interrupted. This could happen
due to radio or cell communication loss or an obstacle between the GeoSteer and the communication source (ex. Base Station
Radio Modem or Cell Tower). “Flex” will not help if the GPS signals from the satellites are blocked by obstacles such as trees
or buildings.
