Anti-Interference User Manual Ⅳ

1. Set Connection1 to connect to the USB2 port of the Mosaic MiniEVK (the corresponding virtual serial port can be viewed through the computer's device manager).
2. Set Connection2 to connect to the differential source via serial port or NTRIP, and confirm effective reception of differential data through "Show Data".
3. Link the differential data from Connection2 to Connection1, so that the MiniEvk board can receive the differential data.

Note: If using Qianxun NTRIP or differential data from other CORS stations, you need to set the port on the board receiving the differential data to output 1Hz GGA data. See the real-time output of NMEA data ports for specific settings.

• RTK Fixed Status Verification

Return to the RxControl software, where you can see the positioning accuracy in the Position Information section.

In the PVT information section at the bottom right, you can see if the current RTK status is RTK Fixed, as well as the satellite systems used for PVT calculation.

The DiffCorr light blinking at the bottom left indicates that differential data is being received in real-time.

 

NMEA Data

Real-time output through ports

• Using the RxControl software, navigate to Communication/Output Settings/NMEA Output/NMEA Output.

 

Intervals setting

d. Output port

e. NMEA data type

f. Output frequency

• Save settings: File/Copy Configuration/Current->Boot

Command line: sno,stream1,ubs2,gga,sec1 // Set USB2 port to output 1Hz GGA

Command line: eccf,current,boot // Save settings

 

Recording Data to a Memory Card

• The Mosaic MiniEvk supports a TF memory card, which can be used to record data to the card.

Using the RxControl software, navigate to Communication/Output Settings/NMEA Output/NMEA Output Intervals.

① Set the output port to DSK1

② NMEA data type

Command line: sno,stream1,ubs2,gga,sec1 // Set USB2 port to output 1Hz GGA

③ Output frequency

• Save settings: File/Copy Configuration/Current->Boot

Command line: eccf,current,boot // Save settings

 

Recording Data to a Computer File

Method 1: Using Datalink

The Datalink program can connect to the USB2 port of the Mosaic MiniEVK. Input commands in the serial port monitoring interface to set the output data, and check the "Log to file" option (see the Datalink program for details).

Method 2: Using RxLogger or RxControl Software Logging

① In the RxControl software, use the Logging/RxControl Logging function or run the RxLogger program, connect to the USB port of the Mosaic MiniEvk, and enter the following interface.

② Under the Global menu, set the Message Types To Log, and check NMEA.

Note: If checked, it needs to be set and recorded. If SBF is not needed, it should be unchecked.

③ Under the File Naming menu, set the file path and file name, with optional settings for individual file size and duration.

④ Under the NMEA menu, set the output data type and interval.

⑤ Click Start Logging to start recording to a computer file.

 

SBF Raw Data

SBF - Septentrio Binary Format is a proprietary binary format file for Septentrio, which records comprehensive information.

Port Output Raw Data

In the RxControl software interface, go to Communication/Output Settings/SBF Output, and set:

① Output port

② Data type - For the required data types, please refer to Chapter 4 SBF Reference in the Mosaic Firmware Guide.

③ Output interval

④  Save settings: File/Copy Configuration/Current->Boot.

Command line: sso,stream1,ubs2,PostProcess,msec200 // Set USB2 port to output 5Hz PostProcess data

Command line: eccf,current,boot // Save settings

 

Recording raw data to a memory card

The method for recording to a memory card is basically the same as for serial port output, just change the serial port number to DSK1.

Recording data to a computer file

The setup steps are the same as for recording NMEA data to a computer file, except change NMEA data to SBF data and ensure that the required SBF data types are selected.

Note: To record SBF data to a computer with a different recording interval, you need to use the RxLogger program. Recording SBF in RxControl cannot be set and defaults to 1Hz.

 

External Event

PPS Output

In the RxControl software interface, navigate to Navigation/Receiver Operation/Timing to set up PPS output and save the settings.

Command line: setPPSParameters,sec1,Low2high // Set 1 PPS output (max 100), pulse from low to high

Command line: eccf,current,boot // Save settings

 

Event

• In the RxControl software interface, navigate to Navigation/Receiver Operation/Timing to set up Event, and configure SBF data logging, making sure to select the Event data type so that position information at externally triggered moments is recorded.

Command line: sso,stream1,ubs2,PostProcess+Event,msec100 // Set USB2 port to output 10Hz PostProcess+Event data

• Save settings

Command line: eccf,current,boot // Save settings

 

SBF Data Analysis

SBF Analyzer

When installing the RxTools software, the SBF Analyzer is automatically installed. Below is a brief introduction to using the SBF Analyzer program:

• Double-click to run the SBF Analyzer program, or right-click on an SBF format file and select SBF Analyzer.

• Check the content you need to analyze, and click Analyze.

 

SBF Convertor

The SBF Convertor program can convert SBF to the desired common format.

• Run the SBF Convertor program or right-click on an SBF file and select Convert SBF.

• It can convert SBF to Rinex, ASCII files, etc.
• For Event applications, use ExtEventPVTGeodetic1 to view the position data recorded at externally triggered moments.

 

Troubleshooting

Diagnostic Report

• There are several ways to obtain a diagnostic report or its content: Connect the board using the RxControl software, go to File/Display Diagnostic Report or press the shortcut Ctrl+C, and then save the report as a PDF file.
• Through the web interface, go to Admin/About/Diagnostic Report, and then Save As to save it as a text file.
• Or, using a serial port assistant, input the following command and copy the content returned by the board to a file.

g. lstInternalFile, Identification

h. lstInternalFile, Permissions

i. getReceiverCapabilities

j. getReceiverInterface

k. lstConfigFile, Boot

l. lstConfigFile, Current

m. lstInternalFile, Ipparameters

n. getSbfOutput

o. getDataInOut

p. lstInternalFile, Error

q. lstInternalFile, SetupError

Support SBF Files

If technical support is needed to analyze data quality or troubleshoot board card anomalies, it is necessary to record Support SBF data. The steps for recording SBF are as follows: introduction to SBF raw data. By default, the Support SBF data can be set to 10Hz, and the recording frequency of Support SBF can be adjusted according to whether the scenario is stationary or moving. It is recommended to select Support+BBSamples to be recorded to an SD card or computer file.

Command Line: sso,stream1,dsk1,support+BBsamples,msec100 //Record support+BBsamples to SD card

Command Line: eccf,current,boot //Save settings
