My receiving setup

Raspberry Pi 4B + QFH antenna

A Raspberry Pi 4B paired with a homemade QFH antenna, capturing weather satellite images from NOAA and Meteor-M2 as they pass overhead — recorded, decoded and archived without me lifting a finger.

How it works

01Antenna

Homemade QFH antenna

A Quadrifilar Helix — circularly polarized and hand-built for the job. It gives clear, reliable reception of the satellite downlink regardless of pass geometry.

02Compute

Raspberry Pi 4B

The heart of the station, running rnv3 to receive and decode passes, turning raw signal into finished weather maps.

03Storage

Pushed here as it happens

The station sends every decoded pass and its images to this site the moment they are ready — an event webhook straight from the Pi into Supabase, ready to serve.
