FieldGenius data collection - RTK base station and rover

There are several different ways to collect data with FieldGenius so that it can be post-processed. The complete list of use cases can be found in the article FieldGenius data collection - Overview.

This article explains how to collect data using RTK base station and rover.

Step by step instructions

1.   Launch FieldGenius on you mobile device.

2.   In the Project Manager window, press New Project and  enter a project name.

3.   Project Settings let you review the parameters associated to the project such as Coordinate System and Units. Press OK when done.

4.   The next window helps you pair your receiver. Press Select Instrument to open Instrument Selection window.

5.   Select GNSS Rover.  If you have already created a profile for the receiver, press Connect and jump to step 10. To create a new profile, press Add.

6.   Enter a name for the receiver and press Save.

7.   Press Edit to set up the parameters for the receiver.

13.   Press the button labelled Standard Measure to define the Measurement Mode to be used to collect points.

Collecting features

15.   Once you finished customizing the tolerances, select one  of them using the upper right button in Instrument Settings window.

After the survey

20.   Once the survey is completed, download the data from the Mobile Device and from the SD card of the rover.

21.   Make sure all files are saved in the same folder (see an example below).

22.   The field data is now ready to be post-processed. Refer to the article How to process GNSS data recorded using FieldGenius for further instructions.

Note: File names given here are for demonstration only. They will vary depending on the receiver you’re using and how you named your project.

Project file from the rover. Import this file in the post-processor to process the features.

The binary (or RINEX) file from the rover will be automatically imported with the corresponding *.raw file.

 Observations: Number of epochs to record for a point.

 Solution: Minimum solution type to record a position. If you want to post-process your data, always use “AUTONOMOUS”; at best, RTK position will be recorded, at worse, a lower quality position will be recorded now and will be replaced later by a higher quality post-processed position.

 Elevation: Required elevation mask.

 PDOP: Minimum  PDOP to consider a epoch as valid.

 Satellites Computed: Minimum number of satellite to consider a epoch as valid (5 is good).

 StdDev Horizontal: Minimum horizontal standard deviation to consider an a epoch as valid (always put a high number if you want to post process your data).

 StdDev Vertical: Minimum vertical standard deviation to consider an a epoch as valid (always put a high number if you want to post process your data).

 Post Process: Do not check this option.

Document information

8.   Enter the antenna height. In Model and Communication, enter the make, the model and the communication port for the receiver.

      In this example, we are using Altus APS-3 connected via Bluetooth on COM1.

9.   Press Connect to initiate the connection.

14.   To set the tolerances, press Instrument Settings and Sensor Configure. There are different tolerance settings to choose from. See a detailed information about Tolerance Setting below.

16.   To collect a feature, press on the action button.

17.   When finished collecting data, stop the raw data logging on the rover by going to Instrument Settings > Raw Data Logging > Stop Logging.

18.   To close the project and the software, press the main button, select Exit and confirm by pressing on Yes.

19.   Finally, stop the base receiver by powering it off.

Rover setup

10.   In Map View, press Instrument Settings button then Raw Data Logging.

11.   On the next screen, make sure the Logging Rate value is set to 1 second.

12.   Press Start Logging. Shortly after, <auto name> will be replaced by the name of the new log file. Press Close to continue.

It is CRITICAL to start the raw data logging before following the next steps.
