:signal_strength: 1090ES ADS-B Out Add-on
This repository contains "ADS-B Out" encoder for Tx-capable SDR hardware.
It is currently written in architecture independent Python language and can be used as an add-on for existing open source "ADS-B In" solutions. One known good example is Stratux.
ES (1090 MHz) variant of ADS-B surveillance technology is being considered here.
For UAT ADS-B (978 MHz) option, please, visit this repository: https://github.com/lyusupov/UAT-test-signal
