Receiver Independent Exchange Format (RINEX) is a data interchange format for raw satellite navigation system data. These files are useful to do PPK (post-processing).
In this tutorial we will guide you through the steps of generating RINEX files from your simpleRTK3B board powered by Septentrio Mosaic RTK module. SimpleRTK3B have onboard datalogging, so everything is easy.
There are two methods for saving logs:
- Using a computer: You can link your receiver to a PC during the datalogging process.
- Using a microSD card: This is ideal when you’re logging data in the field without a connected PC.
If you have a simpleRTK2B receiver, have a look at the tutorial How to build a portable PPK data logger with simpleRTK2B Pro receiver.
Required hardware:
- simpleRTK3B Pro
- USB to USB-C cable
- microSD card (optional if you will do measuring without connecting your receiver to your computer)
- a PC or computer
Required software:
How to generate RINEX files with simpleRTK3B?
- Insert the microSD card into the datalogger slot of your receiver.
If you are going to log data with your receiver connected to your computer, you can skip this step, as you can directly log the data to your PC.
- Connect your receiver to your computer via the USB port labeled with POWER+GPS.
- Open Septentrio web interface by typing 192.168.3.1 in your browser.
- Go to menu–>Logging. At Enable Logging choose Logging on. Click +New SBF stream.
- Choose Rinex.
- Press Ok and Save the configuration.
Via microSD card
Via computer running RxTools software
Via microSD card
- Now you can disconnect your receiver from your PC and do your measuring work. After finishing your measuring work, connect the microSD card to your PC. Store the files and simply rename them from *.TXT to *.SBF.
- Once the SBF data is available. Open RxControl. Go to Tools–>SBF Converter.
- This SBF Converter GUI tool (part of RxTools) can be used to convert binary data into RINEX format as shown below.
- If you are using the simpleRTK3B Heading module, you can select which antenna’s raw binary data to convert into RINEX format.
Via computer running RxTools software
- Open RxTools. Go to Tools–>RxLogger.
- Connect your receiver to RxLogger via Serial Port. Choose the COM port of your Septentio receiver and type in a connection name. Press Finish.
- Go to SBF. Enable SBF data output and logging as in the following picture:
- Once the SBF data is available, then the SBF Converter GUI tool (part of RxTools) can be used to convert binary data into RINEX format as shown below:
- If you are using the simpleRTK3B Heading module, you can select which antenna’s raw binary data to convert into RINEX format.
Now you have the RINEX file prepared and ready for post-processing! If you want to do this tutorial, we have all the products in stock and ready to be shipped:
