GK-2A IR Colour Enhancement

Unfortunately the LRIT downlink only transmits a single Infrared channel called IR105 (10.4μm) due to throughput constraints. This means false colour imagery cannot be created using data from the LRIT downlink alone.

However, interesting imagery can still be created from this single cha...

COMS-1 LRIT Key Decryption

June 26, 2018 - sam210723

Like NOAA's series of GOES meteorological satellites, COMS-1 (128.2°E) operated by the Korea Meteorological Administration (KMA) has both LRIT and HRIT downlinks for disseminating real-time meteorological data. Unlike GOES, these downlinks are encrypted using single-layer DES and decryption keys are controlled by KMA th...
