Getting connected to the Web Interface
Connection between the sensor and your device is established via Bluetooth.
➜ The following instructions are based on using Windows 10.
- Power on the iCG120.
➜ If you intend to use the Web Interface with iCG120 make sure the external Bluetooth antenna is attached. - On your computer go to Start Menu > Settings > Devices. ➜ Activate Bluetooth if not yet switched on.
- Click "Add Bluetooth or other devices".
➜ Make sure that computer and sensor are in reach for a Bluetooth connection. - Click Bluetooth and select the sensor from the list. Wait for the connection to be established.
➜ The sensor can be identified by its serial number. - Go to Start Menu > Settings > Network & Internet. Under Advanced Network Settings click "Change Adapter Options".
In the Network Connections page double-click on "Bluetooth Network Connection".
Finally, right-click on the sensor that you have just added and select Connect using > Access Point from the context menu. - Enter one of the following options into your browser:
• 172.16.0.1
• http://www.icgsetup.leica-geosystems.com
User name is "leica".
When you log in for the very first time enter the serial number of your sensor as default password. - Before you can proceed and use the Web Interface you will next be prompted to change the default password.
• As Old Password enter the serial number of your sensor.
• Define a New Password.
• Enter the new password again to confirm it.
• Press Change to set the new password.
• Use the new password for future log-ins. - Start configuring the iCG120 using the Web Interface.
➜ For mobile devices it is only required to pair the sensor via Bluetooth.
Web Interface - Frame
The header section contains a status information bar. 
The footer includes information on the connected receiver, its serial number and firmware version. 
➜ The frame will always be visible independent of which tab you open for further configuration.
Status information bar
The status bar shows the satellite status, internet connection, antenna configuration and receiver status information.
Home
The Home page is a pure status information page.You will find detailed information on:
• Position/Tracking Status of the connected antennas
• Status of the RTK link
• Status of the communication devices
• Analytics services
Sensor Configuration
The Configuration page allows for configuring device settings such as:
• GNSS settings
• RTK Bridging/PPP settings
• Activation of a coordinate system
• Bluetooth
• Network settings for the Internet connection
• NMEA
• Remote Peripherals
• Security
• Time
• System language
Enable or disable Active Primary Antenna Switch. This feature allows for the receiver to switch automatically between Antenna 1 and Antenna 2 as primary antenna when obstructions prevent Antenna 1 from normal operation.
Enter the Elevation Cutoff to be applied for satellites near the horizon and a Height Offset, if required.
Use RTK Bridging to increase uptime when facing short outages on the RTK infrastructure.
➜ RTK Bridging is available for all RTK formats.
Activate or de-activate PPP. PPP is a Precise Point Positioning service independent of RTK. Being independent from a reference station or a network, it is required that the correct reference frame is selected/generated.
A different Talker ID can be manually entered once it is set to User.
For CQ Control choose between Position only, Position & Height or Height only. When CQ Control is active the CQ Limit must be defined.
Antenna Transpose allows for streaming Antenna 1 and Antenna 2 positions on seperate outputs (NMEA Output 1 and NMEA Output 2).
Once an NMEA link is configured, each NMEA message can be set to stream
at the desired Rate.
Refer to NMEA Message Formats for more details on NMEA messages.
For ORP, besides the desired rate, the following output formats are available: Position 1, Position 1 & 2 or Position 1, 2 & Heading. The Height is
set automatically according to the coordinate system used: Ellipsoidal for
WGS84 and Orthometric for Local Grid.
Refer to ORP – Orientation and Position for further information on ORP.
In the RTK page you can configure the sources for correction of the selected modem/radio.
Refer to: RTK Configuration
Security Configuration
The Security section on the Configuration page allows the configuration of a One-Time password as alternative login.
RTK Configuration
The RTK page allows for configuring the real-time kinematic data link.
➜ In order to use NTRIP/TCP as data link, an Internet connection is required and the Network must be set accordingly (see below).
➜ TCP Local is used by iCON site, Remote Radio is only available when the iCG120 is connected to a CR50 with radio.
The required Bandwidth can be selected from the drop-down list. Bandwidth is dependent on the currently selected frequency.
FEC (Forward Error Correction) allows for safeguarding data integrity in determent of data throughput. This feature requires a match on both, Base and Rover, and availability is dependent on the selected transmission Protocol.
The current Status of the radio is shown.
RSSI indicates radio signal reception quality:
• High: ≥ −80 dBm
• Medium: −81 to −95 dBm
• Low: −96 to −105 dBm
Services: The Services page allows for active services to be configured.
➜ In order to make use of the available services, an internet connection must be established on the sensor. See also: Sensor Configuration
➜ Click the About button to get detailed information on the scope and implications of using iCON Analytics.
Utilities: The Utilities page allows for firmware updates, adding license keys and uploading antenna lists from the connected device or from a USB flash drive on the sensor.
➜ No internet connection required on the sensor.
➜ If a USB flash drive containing firmware files is connected to the sensor, you can directly select the upgrade file from the dropdown list.
To delete files from the sensor press Delete All or select a file from the drop-down list and click Delete (only available for coordinate systems).
Or Click Delete All to delete all User Files, all SSH Public Keys or all Coordinate Systems stored in the internal memory on the sensor.
System Info
The System Info page shows read-only information on the sensor hardware and system status.
Support
The Support page allows for log files handling service ports and resetting single components.
➜ A USB flash drive must be connected. See also: Using USB Memory Devices
Support logs contain LB2 logs taken at a medium rate. If high rate LB2 logs are needed, enable LB2 Logging.
➜ LB2 logs contain raw data information from the visible satellite signals and are required for troubleshooting position or tracking performance issues. Roughly 10 min of LB2 logging are usually
sufficient.
➜ Log file size grows rapidly over time when LB2 is enabled.
Select MC Mode Override to pause CAN communication with the machine temporarily for troubleshooting.
➜ MC Mode Override is always disabled while booting the instrument.
Select HDR to enable interference mitigation measures for positioning on the device.
