This tutorial shows how to use the Stop & Go with ReachView 3 workflow in Emlid Studio to get separate points with precise coordinates from the track of measurements.
With the Stop & Go with ReachView 3 feature, Emlid Studio allows you to get separate points with precise coordinates from the track of measurements using raw data logs recorded on a base and a rover and a CSV file from the ReachView 3 app. This technique can be compared to point collection, but all the required points are obtained after processing.
Stop & Go with ReachView 3 involves the use of a base placed at a known point and a rover attending all unknown points and occupying each one for a short time. That is why this technique called 'Stop & Go'.
The advantage of this technique is that it can be used when it is impossible to provide a real-time correction link between the base and the rover due to insufficient line of sight range, absence of the Internet connection, non-availability of the NTRIP service, etc.
To get separate points with precise coordinates, you will need the following:
- a RINEX observation file from the base
- a RINEX observation file from the rover
- a RINEX navigation file from the base or from the rover
- a CSV file from ReachView 3
If you recorded raw data in the UBX format or got corrections from the NTRIP service in the RTCM3 format, Emlid Studio will automatically convert them to RINEX using the background conversion feature.
Emlid Studio calculates all solutions using RINEX files from the base and the rover and averages them over time spans using a CSV file from ReachView 3 to provide separate points.
If you already post-processed RINEX files from the base and the rover and obtained a .pos file, go straight to the Generating corrected CSV section.
To process the data and get separate points, follow the steps below:
To add a file, simply drag and drop it from your desktop.
- Add RINEX files from the base and the rover as described in the Kinematic processing guide. After processing, the resulting .pos file will be automatically uploaded to the Processed solution field.
Generating corrected CSV
If you skipped the steps above, you need to add the .pos file manually. Drag and drop it to the PPK solution field.
To generate a corrected CSV, follow the steps below:
Add a .csv file from ReachView 3 and tick the required data quality to choose solutions to be averaged.
If you want to get cm-accurate results, tick Fix only.
- Click Start. The result will be shown on the plot.
Click the Show result files button to get the resulting corrected CSV file. Emlid Studio creates a copy of the .csv file named “name_of your-file_corrected.csv".
