Sky Observer for Raspberry Pi (Beta) is a low-cost and modular 1090ES ADS-B receiver, decoder and tracker software runs on Raspberry Pi.
Sky Observer can receive and process ADS-B & Mode-S messages from commercial or homemade ADS-B/Mode-S receiver hardware, extract flight information and make tracking. It can also output flight information in standard ASTERIX category 21 format and JSON format.
Sky Observer is designed to run 7x24, you can safely leave it runing and forget after first setting up.
Sky Observer is capable to process the following types of ADS-B messages.
|ADS-B Message Type||DO-260||DO-260A||DO-260B|

Sky Observer is designed to work with any receiver hardware which can send received Mode-S messages to Sky Observer by LAN, serial or other interfaces.
Currently we are developing and testing it with Radar Cape
We appreciate if any one can support us to interface with other receiver devices!
Sky Observer is able to output received ADS-B tracks in Eurocontrol ASTERIX format.
The supported categories and versions are:
- Target reports in CAT021 version 0.23
- Target reports in CAT021 version 0.26
- Target reports in CAT021 version 2.1
Sky Observer is able to output ADS-B target reprots in JSON format through UDP or HTTP protocol.
