NOAA Weather satellites transmit High Resolution Pictures at 1.7 GHz. The transmission is not encrypted and the USRP SDR and GNU-RADIO can be used for reception and decoding. A steerable directional low noise antenna and a low noise amplifier are required for direct reception.

My Weather Satellite reception setup currently consists of the following:
1) I am still using the 2.5 m dish of the EME (Moon bounce) setup. But I will try using a much smaller antenna and an old IRTE SAT-TV rotator.
3) Helix feed off-set to the 23cm N2UO/W2IMU feed
4) TX/RX switch to isolate the LNA during 1296 MHz / 23cm transmission
5) Lorch 5DF6 band pass filter to suppress cellular interference
6) Home-made 1.7 GHz LNA followed by MMIC amp
7) USRP SDR + WBX daughterboard
8) Demodulation is done using GNU-Radio based POES-USRP on a Linux machine OR with the following GNU-Radio (188.8.131.52) flow graph running on Windows. Download HRPT GNU-radio companion .grc file from my dropbox .
9) For visualization/false color images David Taylor’s excellent HRPT reader is used.
Currently tracking/demodulation/visualization is entirely done on Windows.
By the way, I use GNU-Radio version 184.108.40.206 (not the latest) and instructions how to install this version on Windows 7 32 bit can be found here.
Below is the main flow graph I use on Windows. It outputs an .hmf file on a folder you have to setup in “File Sink”. This .hmf file can be opened with David Taylor’s HRPT Reader.
