BSI delivers 40 Viper DIS Radios to the United States Air Force Distributed Mission Operations Center (DMOC) at Kirtland Air Force Base, New Mexico.  Viper will be used in the DMOC’s battlespace to provide cost effective, realistic simulated radio communications.  Viper is a PC-based DIS radio that supports user defined communication plans and simulates physics based signal degradation, including propagation losses due to frequency spreading loss and Fresnel diffraction over terrain.
