rs1090

rs1090

rs1090 is a Python binding to the rs1090 Rust library to decode Mode S, ADS-B and FLARM messages. It takes its inspiration from the Python pyModeS library.

The direction ambitioned by rs1090 boils down to:

• improving the performance of Mode S decoding in Python;
• exporting trajectory data to cross-platform formats such as JSON or parquet;
• providing efficient multi-receiver Mode S decoding;
• serving real-time enriched trajectory data to external applications.

Installation

pip install rs1090

Usage

For single messages:

>>> import rs1090
>>> rs1090.decode("8c4841753a9a153237aef0f275be")
{'df': '17', 'icao24': '484175', 'bds': '06', 'NUCp': 7, 'groundspeed': 17.0, 'track': 92.8125, 'parity': 'odd', 'lat_cpr': 39195, 'lon_cpr': 110320}

For batches of messages:

>>> import rs1090
>>> rs1090.decode(msg_list)
...
>>> rs1090.decode(msg_list, ts_list)  # includes CPR to position decoding
...
>>> rs1090.decode(msg_list, ts_list, reference=(lat0, lon0))  # useful for surface messages
...

For FLARM messages (also as batches):

>>> msg = "7bf2381040ccc7e2395ecaa28e033a655d47e1d91d0bf986e1b0"
>>> rs1090.flarm(msg, 1655279476, 43.61924, 5.11755)
