station latitude and longitude as the reference point for all GPS position calculations for jobs, 3rd party exports, etc. If the
base station latitude and longitude changes, all job data would be shifted by the same amount which would not be good.
To prevent jobs from shifting when using an unsurveyed base station, when the GeoSteer system starts communicating
with a base station, it first compares the location transmitted by the active base station to the list of internal base stations
locations in the GeoSteer system. If it finds a base station location in its internal list within 32.8 feet (10.0 m) of the location
being transmitted, the GeoSteer system assumes that the base station transmitting is the same one stored in the database.
The GeoSteer system then uses the latitude and longitude stored in the internal database that was originally sent by the
base station as the reference point instead of the one that is currently being transmitted. This ensures that if the position
the unsurveyed base station transmits changes slightly, it does not have any effect on the existing jobs and other data
within the GeoSteer system.
If the GeoSteer system does not find a base station within the distance limit in its internal database, it assumes that it is
listening to a different base station and creates a new internal base station in its database with the new information.
As long as the information on the GeoSteer system is not being shared with other devices, the GeoSteer system can
AutoSteer with an unsurveyed base station with no problems. The GeoSteer system will store jobs and A/B lines and will
be able to repeat those jobs so long as the base station’s GPS antenna is NOT physically moved. Though the GeoSteer
system can operate in this situation, it is not recommended. If additional systems are added to the fleet in the future, all
current jobs and data will not be compatible or transferable to the new systems as the base station reference point the
new systems store in their internal database will be different from the original one. Information will be shifted between
systems.
Because of the limitations of running with an unsurveyed base station, it is highly recommended that the operator allows
the base station to survey in (this takes around 24 hours in most cases). The Base Station Location screen provides the
information to know if a base station has completed the 24 hour survey and once it has, update the internal base station
position to reflect the new surveyed position. A base station that has surveyed in will always send the same latitude and
longitude. Any additional GeoSteer systems that detect it will then also get the same position. This allows all the system to
seamlessly share information among them.
To access the Base Station Location screen, select the GPS tab
from the main AutoSteer Setup screen, press the RTK button,
and then select Base Station Location from the list on the right.
The information and button available in the Base Station
Location screen are:
Saved Location
—This is the location the GeoSteer system has
stored in its internal database for the base station it is receiving
data from. This value will not change.
Currently Received Location
—This is the location that the
active base station is currently transmitting. If the base station is
not surveyed in, this position will slowly change, however if the
base station is surveyed in, this position will stay the same.
Difference
—This displays the distance between the Saved Location and the Currently Received Location. This value will
be zero if the Saved Location was stored from a surveyed base station.
Base Completed 24hr Survey
—This indicates whether or not the base station the GeoSteer system is receiving data
from has completed a 24 hour survey. It will provide the following responses
No
—The base station has not completed the survey and the position it will transmit may be different over time.
Yes
—The base station has completed the survey and the position it will transmit will always be the same.
Update
—This button tells the GeoSteer system to update the latitude and longitude for the Saved Location to match the
Currently Received Location. This should only be performed after the 24 hour survey has completed.

NOTE!: The Update function only works with the base stations that use Novariant's INX correction protocol. This will
not work with base stations providing CMR+ or RTCM.
