RTCM3 Data Parsing Online

TAG gnssrtcm
Using browser capabilities to process files, the files will not be uploaded to the cloud.
When using for the first time, the rtcm3 processing program needs to be loaded, which may take several seconds to tens of seconds. Please be patient.

The byte range of the parsed file content, by default, the entire file is parsed
The rtcm3 message type to be parsed, and all supported rtcm3 message types will be parsed by default

RTCM3 Data Parsing Online-summary

The online RTCM3 data parsing tool supports the parsing of RTCM3 data from navigation systems such as GPS, Beidou, GLONASS, and Galileo. It can parse RTCM3 basic messages, ephemeris messages, and MSM messages, and allows for the downloading and parsing of results.

RTCM3 Data Parsing Online-instructions
  1. Open File : Open the rtcm3 data file. This tool does not impose any size limitations on the rtcm3 files it can open, meaning it can handle even massive rtcm3 data files (such as those in gigabytes).
  2. File Byte Range : In the file, select data within a specified byte range for parsing. The unit is byte. The starting index (inclusive) is greater than or equal to 0, and the ending index (exclusive) is greater than the starting index and less than or equal to the file size. The starting index defaults to 0, and the ending index defaults to the smaller value between the file size and the starting index plus 200MB. End Index - Start Index, the size of the byte range selected, with a maximum support of 200MB. If the opened file is very large, scrolling parsing is required.
  3. Message Type : Fill in the rtcm3 message type for parsing. The default is to parse all rtcm3 message types supported by this tool. For example, if you fill in 1042,1124-1127, then messages of types 1042, 1124, 1125, 1126, and 1127 will be parsed.
  4. After clicking on Parse, the following analysis results will be displayed:
    1. ALL : Display all parsed rtcm3 data frames, including message sequence number (the order of the message parsed in the selected data), message type, message name, message size (in bytes), starting index (the starting index position of the message in the file, inclusive), ending index (the ending index position of the message in the file, exclusive), parsing status, error message, etc.
    2. STATISTICS : Display statistical information on the parsing of rtcm3 data frames, including the total number of messages, the number of messages supported for parsing, the number of messages not supported for parsing, the number of error messages, and the quantity of various types of messages.
    3. ERROR MSG : Display the rtcm3 data frame with parsing errors, including CRC check errors, data frame format errors, etc.
    4. Message Table : Clicking on a specific message type will display a data list of all parsed messages of that type. The data list includes information such as the message type, message name, and data fields of the message. The values of the data fields are the original values parsed from the message and have not undergone secondary calculations (such as multiplication by a scaling factor, formula calculations, etc.). Clicking the tips icon in the column name of the data field will display the definition information of that field. This includes information such as field number, field name, field type, field unit, field scaling, and field description. Note: The field information is automatically generated by OCR recognition and may contain some errors, so it is for reference only.
  5. Display values of various data types in rtcm3:
    1. bit(n) : The data is displayed as a hex string in the data table, and represented as a base64 string in the downloaded JSON file.
    2. char8(n) : Represented as a string.
    3. intX : Represented as a number.
    4. uintX : Represented as a number.
    5. intSX : Represented as a number.
    6. utf8(N) : Represented as a string.
  6. Support parsing of rtcm3 message types.
