You need a radio that can receive the ACARS frequencies, VHF around 130 MHz in the aviation band. It's a simple FSK over AM, like an old-school modem, so you just pipe your radio's audio into a software decoder. There are direct SDR approaches these days too. e.g. ADSB Exchange has a ready-to-go SD card image for Raspberry Pi if you have an SDR which can receive the relevant frequencies. https://www.adsbexchange.com/how-to-feed/ https://www.adsbexchange.com/how-to-feed/
- H8crilA 5y agoACARS is something else, it's like SMS for aircraft. Also interesting data. But this thread is about location: ADS-B (dependent broadcast) and to a lesser degree MLAT (secondary radar interrogation response), both of which primarily operate on 1090MHz. With an unmodified RTL-SDR you can receive both, not at the same time and you'll want to swap antennas since the ranges are so different, but still :). PS. The RTL-SDRs used for ADS-B often feature a modification: an analog filter centered at 1090MHz, which removes all other data but makes the 1090MHz reception better. You shouldn't have the filter if you want to play around on other frequencies with the same device.
