The Linked Simulators Phase LSP of the Systems Integration Test SIT was executed by the Joint Advanced Distributed Simulation JADS Joint Test Force JTF and the Naval Air Warfare Center, Weapons Division NAWCWPNS between August and November 1996. The purpose of the SIT is to evaluate the utility of using advanced distributed simulations ADS to support cost-effective testing of an integrated missile weaponlaunch aircraft system in an operationally realistic scenario. The SIT missions simulate a single shooter aircraft launching an air-to-air missile against a single target aircraft. In the LSP, the shooter, target, and missile were all represented by simulation laboratories. ADS techniques were used to link NAWCWPNS manned flight laboratories representing the aircraft to an air-to-air missile hardware-in-the-loop HWIL laboratory representing the missile. In order for this linking to have utility for the TE of the AIM-9M missile under test the latency of the data exchanged between the laboratories must be sufficiently low and well-behaved so as not to adversely affect the fidelity of the missile laboratory performance. This paper presents the results of the evaluation of latency and its effects on LSP results. Conclusions for TE applications of the LSP ADS configuration are also given.
