Free-space optical communications for tactical applications WP1. Systems and applications from a user perspective

Free-space optical communication (FSO) techniques have the potential to provide new capabilities for information transfer and communication services on the future battlefield. In particular, applications requiring high capacity in terms of bandwidth and relatively high security need to be considered. This work is a part of an information exchange program Technical Arrangement No 108.077 within CEPA entitled "Free-space Optical Communications for Tactical Applications" and contains findings in work package 1. This study was concerned with the use of FSO communication in military applications focussing on tactical scenarios and the future requirements. Several applications were identified and discussed. Tactical reconnaissance utilising a small UAV was found to be a very attractive application involving FSO echniques. Several of the generic scenarios supported this conclusion. Technology demonstrated in an FSO communication link to a light weigth UAV can also be used in other applications involving e.g. littoral environments, optical tagging, helicopters and communication at shorter ranges between troops and vehicles. In addition to the UAV application communication requirements with respect to network enabled capabilities and naval environments were discussed.
