## What it is
Stratux is an open-source ADS-B weather and traffic receiver built on a Raspberry Pi with RTL-SDR dongles, serving aviation data to electronic flight bag apps like ForeFlight and FltPlan Go. This cyoung repository is the deprecated original branch; active development has moved to the b3nn0/stratux fork.

## Use cases
- receive ADS-B weather and traffic in the cockpit
- build a DIY ADS-B receiver with Raspberry Pi and RTL-SDR
- feed weather and traffic to ForeFlight or other EFB apps
- add GPS and AHRS attitude data to a homebuilt avionics setup
- track aircraft traffic with a low-cost software-defined radio

## When to choose
- you want a low-cost open-source ADS-B receiver for general aviation
- you need an EFB-compatible weather/traffic feed without subscription fees
- you enjoy building your own avionics hardware on a Raspberry Pi

## When to avoid
- you want the actively maintained version - use b3nn0/stratux instead
- you need certified or guaranteed-reliable aviation equipment
- you expect support or issue tracking on this deprecated branch

## Facets
- artifact type: application
- maturity: abandoned
- function: networking, monitoring, self-hosted
- domain: hardware, embedded-systems
- platform: embedded, iot, self-hosted
