What you will need
Hovermap unit with Vehicle RTK or Backpack RTK mount and Trimble GNSS receiver configured as per [MISSING: link to Trimble hardware setup article]
Access to a web browser
RTK base station (optional)
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.
Procedure
Step 1: Connect 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 to access the Trimble web interface.
Enter your credentials on the Login page.
The default username is admin and the default password is password.
Step 2: Check the NMEA Installation
Hovermap cannot detect an incorrectly set antenna height so ensure it is properly configured.
To avoid issues, check if the NMEA option is properly installed.
Go to Receiver Status > Receiver Options from the panel on the left. Find the Options panel on the right side of the page.
In the Options column, find NMEA in the list. Then in the Installed column, ensure an "X" is marked next to NMEA.
Step 3: Configure 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 side, click the Configure button for the port that corresponds to the RS-232 Port 1 connection.
In the configuration window that appears, locate the two fields at the top. Set Input to "None" and Output to "NMEA".
Under Serial Port Setup, configure the settings below
Once set Click OK to save your settings. The screenshot below shows the Port Summary page after configuration.
Setting | Value |
|---|---|
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:
Message | Rate |
|---|---|
GGA | 5 Hz |
GSA | 5 Hz |
GST | 5 Hz |
ZDA | 5 Hz |
SVG | 1 Hz |
Step 4: 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:
Setting | Value |
|---|---|
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.
Outcome
The Trimble receiver is now configured for use with Hovermap and ready to capture RTK scan data.
