ECOMOS is a multinational effort within the framework of an EDA Project Arrangement. Its aim is to provide a generally accepted and harmonized European computer model for computing nominal Target Acquisition (TA) ranges of optronic imagers operating in the visible or thermal infrared (IR).

The project involves close co-operation of the defence and security industry and public research institutes from France, Germany, Italy, The Netherlands and Sweden.

ECOMOS uses and combines well-accepted existing European tools to build up a strong competitive position. This includes two TA models: the analytical TRM4 model and the image-based TOD model. In addition, it uses the atmosphere model MATISSE.

The international cooperation work is supported by the national organizations DGA/DT/ST/IP/CGN/OP (France), WTD 91-500 (Germany), IT MoD –CISAM (Italy), DMO/ST/DWS/RMS/SW&IT/ST (The Netherlands) and Försvarets materielverk FMV (Sweden).
