Meteor_demod

Overview

The Meteor-M2 series demodulator is an excellent tool for enthusiasts of satellite weather data, particularly for those interested in decoding signals from the Meteor-M2 Russian weather satellite series. This free, open-source demodulator allows users to work seamlessly with I/Q recordings in .wav format. It's designed to output an 8-bit soft-QPSK file, which can be transformed into images using compatible decoding software. The user-friendly nature of the software makes it accessible to both novices and experts in satellite data processing, providing valuable insights into weather patterns based on satellite imagery.

With its diverse features and dynamic capabilities, this demodulator stands out in the field of satellite demodulation. From supporting multiple modulation schemes to enabling live demodulation on low-power devices like the Raspberry Pi Zero, it showcases innovative solutions for real-time data acquisition and analysis. Whether you're a hobbyist, researcher, or simply curious about meteorological data, the Meteor-M2 series demodulator is a remarkable piece of technology worth exploring.

Features
