Book Description
The Joint Advanced Distributed Simulation (JADS) Joint Test and Evaluation (JT & E) was chartered by the Office of the Secretary of Defense (Acquisition and Technology) in October 1994 to investigate the utility of advanced distributed simulation (ADS) technologies for support of test and evaluation (T & E). The JADS Joint Test Force (JTF) conducted a System Integration Test (SIT) in which ADS was used to support the testing of an integrated missile weapon/launch aircraft system in operationally realistic scenarios. The SIT scenarios simulated a single shooter aircraft launching an air-to-air missile against a single target aircraft. Extensive testing was performed involving two different ADS architectures: (1) A linked laboratory configuration in which the shooter and target were represented by manned flight laboratories and the missile by an AIM-9M Sidewinder hardware-in-the-loop (HWIL) laboratory. (2) A live shooter/target configuration in which the shooter and target were represented by live F-16 fighters and the missile by an AIM-120 Advanced Medium Range Air-to-Air Missile (AMRAAM) HWIL laboratory. Testing was completed in October 1997, and evaluation of the results Supports the conclusion that each ADS configuration has utility for T & E of the corresponding air-to-air missile involved. This paper discusses the following: (1) Description of the two different architectures utilized in the SIT testing. (2) Technical challenges in implementing ADS. (3) Lessons learned from implementing ADS. (4) Conclusions on the utility of ADS-based testing of air-to-air missiles. (5) Benefits of implementing AD S-based testing of air-to-air missiles.

Book Description
The Joint Advanced Distributed Simulation Joint Test and Evaluation (JADS JT & E) was chartered by the Deputy Director, Test, Systems Engineering and Evaluation (Test and Evaluation), Office of the Under Secretary of Defense (Acquisition and Technology) in October 1994 to investigate the utility of Advanced Distributed Simulation (ADS) technologies for support of Developmental Test and Evaluation (DT & E) and Operational Test and Evaluation (OT & E). The program is Air Force led, with Army and Navy participation, and is nominally scheduled for five years. The JADS JT & E is tasked in three areas: Investigate the present utility of ADS for T & E; Identify the critical constraints, concerns, and methodologies when using ADS for T & E; Identify the requirements that must be introduced into ADS systems if they are to support a more complete T & E capability in the future. The JADS JT & E is executing its charter by evaluating the application of ADS to the T & E of representative military systems. The types of systems selected represent three slices of the T & E spectrum: a System Integration Test (SIT) which explores ADS support of air-to-air missile testing, an End-To-End (ETE) test which explores ADS support for Command, Control, Communications, Computers, and Intelligence (C41) testing, and an Electronic Warfare (EW) test which explores ADS support for EW testing. The JTF will broaden the conclusions developed in the three dedicated test areas by leveraging off of ADS activities sponsored and conducted by other agencies. The SIT consists of two phases. The first phase, the Linked Simulators Phase (LSP), has been completed and employed an all-simulator architecture for testing an AIM-9 Sidewinder missile. The second phase is now underway and links live shooter and target aircraft to an AIM-i 20 AMRAAM hardware-in-the-loop (HWIL) simulation at Eglin AFB.

Book Description
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 weapon/launch 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 T & E 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 T & E applications of the LSP ADS configuration are also given.

Book Description
The Live Fly Phase (LFP) of the Systems Integration Test (SIT) was executed by the Joint Advanced Distributed Simulation (JADS) Joint Test Force (JTF) and the 46th Test Wing at Eglin AFB, FL during 1997. 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 weapon/launch 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 LFP, the shooter and target were represented by live aircraft and the missile by a simulator. ADS techniques were used to link two live F-16 fighter aircraft flying over the Eglin Gulf Test Range to the AMRAAM AIM-120 hardware-in-the-loop (HWIL) simulation facility at Eglin. In order to successfully integrate these assets for a near real-time test, the JADS team learned several lessons during the risk reduction and test execution phases. The lessons highlighted here concern test control aspects, computer processing, and telemetry issues. Control of a distributed test dealt with tactical aircraft control, scenario and data collection decisions, collocation of critical project personnel, and voice communications. Computer processing lessons dealt with simulated GPS data, pre-processing live GPS data from several aircraft pods, creation of an aircraft to HWIL-missile interface, and contingency planning for real-time malfunctions. Telemetry issues concerned aircraft and terrain shielding, and an implementation to handle random sensor dropouts. These lessons would be applicable for other projects when coupling live and virtual assets for evaluation of fire control radars or precision guided munitions. Many lessons on control and processing also apply to simulation tests which link distributed facilities.

Book Description
The System Integration Test (SIT) investigated the ability of ADS to support air-to-air missile testing. This report describes the outcome of the SIT, the conclusions and lessons learned, and offers observations on the implications of SIT for the general class of precision guided munitions (PGM). SIT results indicate that activities ranging from parametric analyses to integrated weapons system testing are both practical and cost effective. Through a process of inductive reasoning we can transfer some of the SIT-based specifics to the general class of (PGM). In general, the elements of the SIT architectures are basic to all PGM cases. There is: (1) a launch platform or shooter; (2) PGM; (3) an intended target; (4) an operating environment (to include countermeasures); and (5) a test control center. The shooter, PGM and target can be represented in any of the three forms associated with distributed simulation: live, virtual, or constructive. We do not see a one-for-one transfer of SIT techniques to other tests. We do see a transfer of the principles, design processes, and methodologies used in SIT. We see no technical impediments, at the conceptual level, to implementing high-fidelity countermeasures in ADS. The SIT suggests strongly that ADS has good potential for improving PGM testing.

Book Description
This summary is designed to serve as a stand-alone document as well as part of this report. For that reason, the reader will find some duplication of verbiage and figures between the summary and the fill report. The Naval Air Warfare Center Weapons Division (NAWCWPNS) was a committed and effective partner for the Joint Advanced Distributed Simulation Joint Test and Evaluation (JADS JT & E) Joint Test Force (JTF) in the planning, preparation, and execution of the Linked Simulators Phase (LSP) of the System Integration Test (SIT). The JADS JT & E was chartered by the Deputy Director, Test, Systems Engineering and Evaluation (Test and Evaluation), Office of the Under Secretary of Defense (Acquisition and Technology) in October 1994 to investigate the utility of Advanced Distributed Simulation (ADS) technologies for support of Developmental Test and Evaluation (DT & E) and Operational Test and Evaluation (OT & E). The program is Air Force led, with Army and Navy participation. The JTF manning includes 23 Air Force, 13 Army, and 2 Navy. Science Applications International Corporation and Georgia Tech Research Institute provide contracted technical support. The program is nominally scheduled for five years. The JADS JT & E is directly investigating ADS applications in three slices of the T & E spectrum: a System Integration Test (SIT) which explores ADS support of air-to-air missile testing, an End-To-End (ETE) test which explores ADS support for Command, Control, Communications, Computers, and Intelligence (C4I) testing, and an Electronic Warfare (EW) test which explores ADS support for EW testing. The JTF is also chartered to observe, or participate at a modest level, in ADS activities sponsored and conducted by other agencies in an effort to broaden conclusions developed in the three dedicated test areas.

Book Description
The Live Fly Phase (LFP) of the Systems Integration Test (SIT) was executed by the Joint Advanced Distributed Simulation (JADS) Joint Test Force (JTF) and the 46th Test Wing at Eglin AFB, FL during 1997. The purpose of the SIT was to evaluate the utility of using advanced distributed simulation (ADS) to support cost-effective testing of an integrated missile weapon/launch aircraft system in an operationally realistic scenario. The SIT missions simulated a single shooter aircraft launching an air-to-air missile against a single target aircraft. In the LFP, the shooter and target were represented by live aircraft and the missile by a simulator. ADS techniques were used to link two live F-16 fighter aircraft flying over the Eglin Gulf Test Range to the AMRAAM AIM-120 hardware-in-the-loop (HWIL) simulation facility at Eglin. In order for this linking to have utility for the T & E of the AMRAAM missile under test, the latency variations between the live aircraft and the missile HWIL simulation facility had to be removed so that the aircraft entity state and missile launch data could be properly synchronized to the missile simulation. This paper presents the techniques used to synchronize inputs to the missile HWIL simulation and their effectiveness at achieving the required degree of synchronization. Also, the resulting latency is characterized, and conclusions on T & E applications of the LFP ADS configuration are given.

Book Description
Since T & E using ADS is relatively new and continues to evolve, there are a paucity of tools available for general use that allow new T & E ADS personnel to evaluate the quality of their ADS system The quality focus of the tools presented is upon tools to assist in the detection of time errors, network-induced errors, and PDU-generation errors. Tools were developed that proved useful. These will be presented. The purpose of JADS testing is to assess the utility of ADS for T & E. This purpose is being accomplish through the execution of three distinctly separate tests. The first of these is called the System Integration Test (SIT). The first phase of this test is the Linked Simulators Phase (LSP). It is this first phase of the first test that has recently been completed and which is the basis for the tools presented. The SIT LsP tests simulate a shooter aircraft launching an air-to-air missile against a target aircraft. The shooter, target, and missile are represented by geographically separated simulators. The shooter is represented by the F/A-18 Weapon System Support Facility (WSSF) at China lake, CA. The missile is the AIM-9 Sidewinder Simulation laboratory (SIMLAB), also at China Lake, CA. The target is represented by the F- 14 Weapons System Integration Center (WSIC) at Point Mugu, CA. Test control of this distributed test will be done from the Test Control and Analysis Center (TCAC) located at the JADS JTF in Albuquerque, NM. The SIT LsP test replicates a "baseline" live fire test. The test evaluation method is to compare ADS test results with results from the identical "baseline" test (This is a simplified view of the JADS testing ... but it suffices for this discussion). Data collection and storage, the data analysis system, and time synchronization topics are reviewed as preparatory material for the presentation of the tools that have been developed.

In the LFP, the shooter and target were represented by live aircraft and the missile by a simulator. ADS techniques were used to link two live F-16 fighter aircraft flying over the Eglin Gulf Test Range to the Advanced Medium Range Air-to-Air Missile (AMRAAM) AIM-120 hardware-in-the-loop (HWIL) simulation facility at Eglin. This configuration had both DT and OT characteristics. There was a DT flavor because an HWIL facility was used to simulate the missile. This allowed the detailed performance of missile subsystems to be monitored, typical of a DT test. The OT characteristics of the LFP resulted from the use of aircraft performing operationally realistic engagements. Two baseline scenarios were selected from the AMRAAM FOT & E(2) live fire test series and modified for replication in the LFP trials. There were four major test objectives of the LFP: (1) Assess the validity of AMRAAM data generated in the LFP ADS configuration. (2) Assess the ability of the LFP ADS configuration to perform AMRAAM testing. (3) Assess the ability to link live aircraft to a missile HWIL simulation. (4) Evaluate the ability of the LFP ADS configuration to support distributed missile testing. This paper describes the LFP testing that was conducted during 1997, presents the results from evaluating the test objectives, and summarizes the utility of the LFP ADS configuration for air-to-air missile T & E.

Book Description
The Joint Advanced Distributed Simulation Joint Test and Evaluation (JADS JT & E) was chartered by the Deputy Director, Test, Systems Engineering, and Evaluation (Test and Evaluation), Office of the Secretary of Defense (Acquisition and Technology) in October 1994 to investigate the utility of advanced distributed simulation (ADS) technologies for support of development test and evaluation (DT & E) and operational test and evaluation (OT & E). The Electronic Warfare (EW) Test evaluated the utility of ADS to support EW systems testing. The EW Test was built on four discreet efforts intended to provide insight into the limitations of technology supporting ADS, the fundamental requirements that ADS architectures must support for EW T & E, and the application of ADS to EW testing. These efforts were 1) JADS-sponsored and managed self-protection jammer test, 2) OSD CROSSBOW Committee-sponsored Threat Simulator Linking Activity, 3) Defense Modeling and Simulation Organization (DMSO)-sponsored High Level Architecture (HLA) Engineering Protofederation (EPF), and 4) Army-sponsored Advanced Distributed Electronic Warfare System (ADEWS) development program. Each effort is described and results are discussed in this report.
