NTRIP
110 GeoSteer System
• OmniSTAR Flex to WAAS/EGNOS/Autonomous Mode – This mode is displayed only if the GeoSteer detects that an
OmniSTAR Demodulator has been installed on the GeoDock. If the system is running in OmniSTAR mode, the user has
the option to “Flex” back to WAAS, EGNOS, or Autonomous Mode if the OmniSTAR signal is lost for some reason. The
mode the system will “Flex” to will depend on which region the GeoSteer is located. WAAS and EGNOIS are available in
North America and Europe respectively. Autonomous Mode is available for the rest of the world. Once the OmniSTAR
signal has been required, the system will return back to OmniSTAR mode.
• WAAS/EGNOS Only – This mode is only available where WAAS or EGNOS are available. The GeoSteer will only use
the WAAS/EGNOS signal for corrections even if an OmniSTAR or RTK signal is available.
• Autonomous Pass-to-Pass – This mode is only available in areas where WAAS or EGNOS are not available. The
GeoSteer will use the GPS signals themselves to calculate reduce the error of the position. This mode allows the system to
run with no correction sources.
Follow the procedure below to change the Precision Settings:
1. From the GPS menu, press the Precision Settings button.
2. Press the Gray Up/Down buttons or directly select the desired Precision Mode from the list.
3. Press the Apply button to activate the selection.
4. The Active Mode will change to show the mode has changed.
NTRIP
Note: The NTRIP button is only available if NTRIP Feature Code has been activated. Contact your AutoSteer dealer for costs
and NTRIP availability.
The NTRIP (Network Transport of RTCM via Internet Protocol) is a standard communications protocol for providing RTK
correction data over the internet. NTRIP requires a way to access the Internet while the vehicle is moving through the field.
This is usually accomplished by connecting the vehicle to the Internet with a Cell Modem with a data plan. GeoSteer has a
built in Cell Modem that allows the system to connect directly to the Internet and receive NTRIP data once properly set up.
NTRIP also requires a NTRIP provider. The NTRIP provider provides RTK information to the vehicle over the Internet
connection. Some areas have access to this information for free. Other areas may be required to pay a fee for these services. It
is up to the user to locate and negotiate access to the NTRIP provider’s data.
Note: Actual NTRIP coverage may vary depending on availability, equipment, terrain, signal strength, weather conditions and
other limitations. Contact your AutoSteer dealer for information on NTRIP service providers in your area.
NTRIP data providers can send data in multiple formats. GeoSteer currently supports the following data stream types:
• CMR+
• RTCM 2x
• RTCM 3x
The NTRIP screen enables user to setup a connection to an NTRIP based RTK correction source via the internal Cell Modem
and contains the following options:
• General – Provides the basic information about the NTRIP stats and connection information.
• Profile – This provides a list of the various NTRIP streams that have been configured.
To access the NTRIP screen, press the NTRIP button from the GPS screen.
