For the both earth observing satellites KompSat-3 (launch 2011) and KompSat-3A (launch 2013) DLR-OS got the order from the South Korean space agency KARI (Korea Aerospace Research Institute) to design and assemble the complete Focal Plate Assembly (FPA), each consisting of 2x PANchromatics and 4x MultiSpectral Focal Plate Modules (FPM).

Hereafter the K3A PANchromatic FPM will be described shortly.
