Latitude: -32.113, Longitude: 116.013 Software: WXtoImg version 2.11.2 beta Receiver: unknown Antenna: 2m Yagi. Weather satellite images recorded at Mesa, USA. Latitude: 48.210, Longitude: 9.140 Software: WXtoImg version 2.10.11 Receiver: APT-06AD. So those who want to try something simple to decode can be advised to hurry up. Weather satellite images recorded at Perth, Australia. Weather satellite images recorded at Trochtelfingen - Haid, Germany. The NOAA satellites are about 20 years old, and when they finally will retire, the new ones will most likely be digital and format will be much more complex (the new Russian Meteor-M2 satellite is already transmitting digital data at 137 MHz). This website is powered by WXtoImg (2.10.7) - damn clever. Interesting to mention, that there are not so many operational radio communication systems in the world, the signal of which can be decoded using 20 lines of code. FAQ Technical and status information on the NOAA weather satellites.
Of course the image is only grayscale (or in Dmitrii's case he decided to use greenscale), but adding false color and various other image enhancements are just standard image processing techniques.
Satellites can be polar orbiting (covering the entire Earth asynchronously), or geostationary (hovering over the same spot on the equator). This is then followed by a for loop that calculates the pixel luminosity from the decoded data, and plots it onto an image file. A weather satellite is a type of satellite that is primarily used to monitor the weather and climate of the Earth. Dmitrii's post shows how a simple Hilbert transform is used on the APT audio which is essentially the entire decoding step.

The software supports recording, decoding, editing, and viewing on most versions of Windows, Linux, and Mac OS X.WXtoImg supports real-time decoding, map overlays, advanced colour enhancements, 3-D images, animations, multi-pass images, projection transformation (e.g.

Over on his blog post Dmitrii Eliuseev explains how only 50 lines of Python code are required to decode an image from the received APT audio. WXtoImg is a fully automated APT and WEFAX weather satellite (WXsat) decoder. However many people may not know how simple the APT signal DSP code is. NOAA 17) 6 maximum elevation of satellite pass 7 azimuth at maximum elevation (E or W) 8 direction of pass. There are already many image decoders for the NOAA APT weather satellites available, with the most common and feature rich program being the abandoned freeware " WXtoIMG".
