Abstract

The merger of the GIESim JTIDS simulation with JSAF added tactical communications modeling to JSAF, and posed several challenges that are overviewed along with solutions and lessons learned. Tactical communications play an increasingly critical role in military operations. JSAF is a large multi-forces simulation that is often employed for war-gaming, however JSAF currently does not model tactical communications. Also the merger of the JTIDS/Link-16 capabilities from GIESim with JSAF is a first step toward applying the GIESim rapid communications modeling approach to a large simulation environment. This paper addresses the physical and logical simulation architectures, modifications of HLA interfaces and internal logic, determination of mission goals and scenario development, associated network design, and component integration associated with the GIESim-JSAF merger. Both JSAF and the GIESim JTIDS simulation were modified to allow JSAF to pass a message through the JTIDS simulation. Substantial work was required to make this happen. Perhaps the greatest challenge was that JSAF did not have logic to handle tactical communications at all. Furthermore, JSAF needed to drive platform position updates into the JTIDS simulation so that accurate radio propagation calculations and correct network transmissions would occur. M&S interoperability between JSAF and the JTIDS simulation needed to be demonstrated in a way that tested interoperation and that had a quick impact on an observer. Therefore, an operationally relevant scenario was developed to demonstrate the value of adding communications modeling to JSAF. Current success and future possibilities will be presented.
