I currently receive images from two different types of satellites.
The first being the 3 operating NOAA Satellites (NOAA 15, 18 & 19)
The second being from the Russian Meteor Satellite METOER M n2
The NOAA images are decoded and processed using WXtoimg and the Meteor images are processed using MeteorGIS. Both programs take the latest images and make a composite over the last few hours.
Meteor Sometimes changes the sensors that it sends down. When using sensors 1, 2 &3 the RGB123 image will update. Currently as of writing 28/08/21 it is using sensors 2, 4 & 6. during this time the thermal, IR & IR Rainfall Images will update.
