Parser for Iridium SBD MO messages from Iridium Solar Edge devices, for sediment traps in the Tale of Three Systems project on R/V Sikuliaq in June-July 2023.
This provides a set of simple command-line tools to decode SBD messages and the information encoded in the messages.
To use these tools, it's recommended to install pipx and then use pipx to install the tools, via the following command in your terminal:
pipx install git+https://github.com/ethanjli/tots-iridium-sbd-parser.git
Then you can run the tots-sbd-decode tool (for decoding a single SBD file) in your terminal as:
tots-sbd-decode [sbd-filename]
where you should replace [sbd-filename] with the path of the Iridium SBD MO (mobile-originated) file you're trying to parse. If you want to decode an SBD MO message with a 3DES-encrypted payload, you can also provide a key file:
tots-sbd-decode [sbd-filename] --key [key-filename]
where you should replace [key-filename] with the path of the key file you want to use. The key file should consist of a 48-character hex-encoded string, for example:
8DE483E58FE9DFE3FCB3EE48C29C77850DEB7BBDC4EE6808
If you'd instead prefer to decode all SBD files in a CSV history report file downloaded from MetOcean LiNC, you can run the tots-report-decode tool in your terminal as:
tots-report-decode [report-filename]
where you should replace [report-filename] with the path of the history report CSV file you're trying to parse. You can also provide a set of decryption keys, so that keys will automatically be selected as needed based on the IMEI associated with each SBD message included in the report CSV file:
tots-sbd-decode [report-filename] --keys [keys-directory-path]
where you should replace [keys-directory-path] with the path of a directory which has keyfiles (of the same format as the keys used by tots-sbd-decode) whose filenames are of format [IMEI].3des-key (e.g. 300434064056620.3des-key) where the IMEI in the key's filename matches the IMEI specified in some row of the history report CSV file.
If you already have Poetry installed, you can run poetry install and then you can run any of the commands listed above, replacing tots-sbd-decode with poetry run tots-sbd-decode and tots-report-decode with poetry run tots-report-decode.
