GOOD PASS

NOAA and Meteor weather satellites orbit at ~800km. When they pass overhead AwareStation captures their 137 MHz signal using a Discone antenna and decodes weather images automatically.

How the station works

The AwareStation PC at home runs SDR software connected to discone and specialist antennas. It scans the radio spectrum, logs signals, calculates satellite pass times, and pushes data to this page every 30 seconds. No antenna or receiver hardware is ever directly exposed to the internet.

📻

SDR Dongle

A low-cost USB radio receiver that can tune anywhere from 25 MHz to 1.7 GHz.

📡

Discone Antenna

A wideband antenna in the attic that receives signals across most of the spectrum.

🛰️

Weather Satellites

NOAA and Meteor satellites send live weather images at 137 MHz as they pass overhead.

✈️

ADS-B Aircraft

Every commercial aircraft broadcasts its position at 1090 MHz. The station picks these up and logs them.
