Since I am only interested in aircraft which operate locally, and I don't need geographic displays etc. (already well supported by websites such as [ADSBexchange](https://adsbexchange.com/)).\n\nIn addition, I want to know more about the aircraft than is reported via ADSB (i.e. aircraft model and registration).  To learn more, I use [ADSBexchange](https://rapidapi.com/adsbx/api/adsbexchange-com1) which offers an inexpensive REST API.  For best results, I collect from ADSBexchange on each observation.\n\nTo learn about nearby aircraft, I have set up multiple collection stations to observe ADS-B and UAT broadcasts.  The observed broadcasts are collected into a PostGreSQL instance for analysis and simple reports are generated.\n\nUML Component Diagram [here](https://github.com/guycole/mellow-hyena/blob/main/uml/hyena-component.png)\n\n## Collection\nADSB Collection runs on a standard [Raspberry Pi](https://www.raspberrypi.org/) using a [rtl-sdr](https://osmocom.org/projects/rtl-sdr/wiki/rtl-sdr) running [dump1090](https://github.com/antirez/dump1090) or [dump978](https://github.com/mutability/dump978).\n\nCollection runs once per minute from cron(8).  The collected output is written to json formatted file and uploaded to [AWS S3](https://aws.amazon.com/pm/serv-s3) for later processing.\n\nThere can be multiple collection stations writing to AWS S3.\n\nMore on ADSB collection [here](https://github.com/guycole/mellow-hyena/tree/main/src/adsb-collect/README.md) and UAT collection [here](https://github.com/guycole/mellow-hyena/blob/main/src/uat-collect/README.md)\n\n## Processing\n\nProcessing consists of moving collected ADSB observations from S3 to a machine for parsing and loading into postgres.  \n\nMore on observation processing [here](https://github.com/guycole/mellow-hyena/blob/main/src/back-end/README.md)\n\n## Reporting\n\nmellow-hyena produces simple reports about upload and observations.  \n\nMore on reporting [here](https://github.com/guycole/mellow-hyena/blob/main/src/back-end/README.md)\n\n## Relevant Links\n\n1.
