This video complements the setup guide to show you how to configure and set up supported Trimble receivers (R12/R12i and R10/R10-2) for use with Emesent's Backpack or Vehicle RTK units, view the RTK status in Commander, and process your scan in Aura.

Overview
This document shows how to configure and set up supported Trimble receivers for use with Emesent's Backpack or Vehicle RTK units.
The term "Trimble receiver", used throughout this guide, refers specifically to the devices supported by Vehicle RTK and Backpack RTK devices. Currently, these include the Trimble R12/R12i and R10/R10-2 receivers.
Scope
This document will not cover the setup of the Trimble receiver from scratch, connecting the receiver to the Field Controller, or connecting to a base station or network corrections service.
It is recommended that the receiver be configured through the Trimble web interface rather than the Trimble controllers to avoid overriding the receiver's settings.
Requirements
The following are required to set up the Trimble receiver:
Hardware | Details |
Computer | PC or Laptop Latest version of Chrome, Firefox, Safari, or Edge |
Emesent RTK unit |
Backpack RTK Vehicle RTK |
Emesent accessories |
GNSS adaptor Mounting plate |
Cable | Emesent Trimble GNSS cable |
Configuring the Trimble Receiver
Connecting to the Trimble Receiver
-
Turn on the Trimble receiver then connect to the receiver’s Wi-Fi network.
-
Once connected, enter 192.168.142.1 in the URL address bar on your Web browser.
-
Enter your credentials on the Login page.
-
The default username is admin
-
The default password is password
-
Checking the NMEA Installation
To avoid issues, check if the NMEA option is properly installed.
-
Go to Receiver Status > Receiver Options from the panel on the left. From the panel on the right, click Option Detail located at the bottom.
-
In the Options column, find NMEA in the list. Then in the Installed column, ensure an "X" is marked next to NMEA.
Configuring the NMEA Settings
Once connected, configure the NMEA settings to make sure the Trimble receiver can communicate properly with the Hovermap.
-
Go to I/O Configuration > Port Summary on the left panel. On the right panel, click Serial (under the Type column).
-
In the configuration window that appears, locate the two fields at the top of the page. Click on the drop-down arrow for the first field and select Serial1/Lemo from the list. Then for the second field, choose NMEA.
-
Under Serial Port Setup, configure the following settings:
-
Baud = 115200
-
Parity = N
-
Flow = Disabled
-
-
In the Input/Output section, you will see a list of NMEA messages. Click on the drop-down arrow beside each of the following messages and configure their settings:
-
GGA = 5 Hz
-
GSA = 5 Hz
-
GST = 5 Hz
-
ZDA = 5 Hz
-
SVG = 1 Hz
-
-
Click OK to save your settings. The screenshot below shows the Port Summary page after configuration.
Configure the Tilt and Antenna Height
-
Go to Receiver Configuration > Antenna on the left panel.
-
From the available options on the right panel, configure the following settings:
-
Antenna Measurement Method = Antenna Phase Centre
-
Antenna Height = 0.000
-
Using Tilt Compensation
If the Antenna Height is set to 0.000, tilt compensation settings will not apply. However, it is still recommended to disable tilt compensation for optimal performance. To do this, go to Receiver Configuration > INS then unselect the INS Enable option, then press OK to save the settings.
Receiver Motion Profile
If your Trimble receiver is mounted on a vehicle, to get the best results make sure that Receiver Motion is set to Kinematic or another appropriate model. This setting can be found under Receiver Configuration > Position. Click OK to save the setting.
Connecting to Hovermap
-
Attach the Hovermap and Trimble receiver to the Vehicle RTK or Backpack RTK unit. Refer to the Vehicle RTK User Manual and Backpack RTK User Manual for instructions.
NOTE: When using the R12, use the Trimble 50mm quick-release spacer and the 100mm Emesent spacer to ensure the correct offset. -
Once attached, plug the GNSS adaptor cable into the RTK mount and fasten the adaptor to the magnetic plate.
-
Plug the Trimble cable with the wire loop into the receiver and the other end (Black Lemo) into the Adaptor port. The Trimble receiver should now be set up to work with your Vehicle RTK or Backpack RTK unit.
Monitoring RTK Status
The Emesent Commander application provides clear visibility of the RTK status before and during the mission. This enables you to monitor RTK quality without leaving the app to check for information via Trimble’s native application.
If the settings are configured correctly and the Trimble receiver is properly connected, Emesent Commander will display the Position and Accuracy without errors. Any communication errors are displayed as a warning notification in the app.
Hovermap cannot detect an incorrectly set antenna height so ensure it is properly configured.
Processing RTK Data
-
Open Emesent Aura and in the Process tab, click Process Scan.
-
In the Configure New Scan Job panel, select the Process workflow.
-
Click Add Dataset then browse for the folder that contains the raw RTK data to be processed. Select that folder.
-
You will be prompted once RTK data is detected in your dataset. Toggle on Use RTK data.
-
In the Location field, enter the preferred name for the output folder. A subfolder is created, which stores all the processed results and data.
-
Click Processing Settings. Under Georeferencing in the General tab, select the RTK device and GNSS receiver used to capture the RTK data.
NOTE: For optimal results, ensure that the Georeferencing mode and GNSS receiver type match the hardware used during data collection. While the resulting point cloud remains usable, the accuracy may be affected. -
Under Base coordinate reference system, set the Coordinate Reference System in which the data was originally collected. This information is essential for accurate transformations and reprojections to the target CRS if you are reprojecting the point cloud.
-
Click Save to apply the settings and return to the main screen. Then, click Start to process the scan.
