To get up and running – the guide follows these key steps.

  • Configure Emlid Reach RS3 using Emlid Flow to stream NMEA
  • Connect the receiver to Windows PC over Bluetooth
  • Configure 12d Field to connect to the Emlid receiver
  • Configure 12d Field to use tilt corrections

… based on the following software & firmware versions:

  • Emlid Reach Firmware version 32
  • Emlid Flow App version 10.9
  • 12d Field version 15 C1p

Watch the video, or follow the steps with screenshots below.

Configure Emlid Reach using Emlid Flow to stream NMEA

For the best performance, 12d software benefits from position streaming rates using NMEA to be at least 5Hz – preferably 10Hz. In order to output at 10Hz, the GNSS update rate needs to be 10Hz.

Step 1 – Open Emlid Flow, connect to the receiver

Go to  Settings > GNSS settings 

Set the GNSS update rate to 10Hz

Step 2 – Set Position streaming settings 

Go to Settings > Position streaming 1 > Bluetooth

In Bluetooth, set Format to NMEA

NMEA settings should be configured to:

  • Do not compensate receiver position
  • Talker ID – set to GN
  • GGA and GST set to 10Hz
  • GSA and GSV set to 0.5Hz
  • RMC, VTG, ZDA and EMP turned off.

Step 3 – Enable Reach RS3 to be found as a Bluetooth device by the Windows tablet

Go to Settings > Bluetooth > Discoverability > On

 

Connect to the receiver on Windows

Step 4 – Add a new bluetooth device on Windows in the Bluetooth & other devices menu

Select the Reach device from the list to pair it to your computer.

Configure 12d Field to talk to the Emlid receiver

Step 5 – Download the installer file 

Install 12d Field 15 C1p or later, which has the Emlid driver built in.

Step 6 – Configure N values and Projection

Using the following guide – ensure you select the correct zone with the projection you are using https://12dwiki.com.au/12df-using-a-gsb-for-n_values-instead-of-winter-files-and-tdf_hel/

Step 7 – Configure 12d to use Emlid GNSS

A. Open 12d Field from within 12d Model
B. Change the setup

C. Instrument selection

Primary type: GNSS

Primary instrument: select GNSS-Emlid

Choose: Set to keep the settings

 

 

D. For Phase centre use 134mm (0.134) for the RS3

In Geodetics section
– Localisation type: None
– Projection:  Use the custom projection defined in step 6 above.
– N value source: 12d

Choose: Set to keep the settings

 

 

E. Select the correct device from the list of Bluetooth devices. 

Click “Search for bluetooth devices” if it does not
appear – this can take a while.

When search is complete, Select the Reach RS3
from the list of Bluetooth devices and
choose Set to keep the settings.

F. The Testing Connectivity screen will appear.

If successful, a check box will appear against
each stage of the test.

The GNSS status window should appear – Green confirms the setup is working correctly.

Step 8 – Use tilt corrections

Press the button to configure tilt. 

From the Tilt dropdown select Use tilt corrections.

 

 

 

 

 

 

 

Step 9 – Check status

Press GNSS status button to check the status of the solution, position and tilt corrections.

The three tabs show Status, Position and Tilts information

 

Check, check and check again

Now you are receiving NMEA strings from Emlid Flow and you should be able to get a FIX solution in 12d Field. We need to confirm if the Phase Centre Offset and Geoid-Ellipsoid separation values are being applied properly, and if the tilt is working.

Step 10 – Check against high quality PSM

Go to a nearby permanent mark with a high quality horizontal and vertical position and do some checks. Record an observation from within Emlid Flow, ensuring you have the correct Geoid selected.

Do the same within 12d and compare the coordinates – are they close to each other? Are they close to the published coordinates for the mark?

Happy 12d Fielding!
