AbstractWith the increased concerns for reducing cost and improving reliability in today's telemetry systems, many users are employing simulation and automation to guarantee reliable telemetry systems operation. Pre-Mission simulation of the telemetry system will reduce the cost associated with a loss of mission data. In order to guarantee the integrity of the receive system, the user must be able to simulate several conditions of the transmitted signal. These include Doppler shift and dynamic fade simulation. Additionally, the simulator should be capable of transmitting industry standard PCM data streams to allow pre-mission bit error rate testing of the receive system. Furthermore, the simulator should provide sufficient output power to allow use as a boresite transmitter to check all aspects of the receive link. Finally, the simulator must be able to operate at several frequency bands and modulation modes to keep cost to a minimum.

Temporal, Spectral, and Spatial Treat Simulation Using a Towed Airborne Plume Simulator (TAPS)Taylor, Rick; Redmond, Neal; Balding, Jeff; Science Applications International Corporation; Center for Countermeasures (International Foundation for Telemetering, 2009-10)Efforts are underway to develop Infrared countermeasure (IRCM) systems to defend aircraft against IR guided surface-to-air (SAM) and air-to-air (AAM) missiles. One such system is the Large Aircraft Infrared Counter Measure (LAIRCM) which employs temporal, spatial, and spectral missile warning techniques. There is no current technique however, for installed system flight testing of such countermeasures in a realistic temporal, spatial, and spectral environment. This paper is an introduction to the Towed Airborne Plume Simulator (TAPS), a system designed to address this test shortfall. The TAPS operational concept is described as well as techniques for simulating missile signatures.
APPLICATIONS AND DESCRIPTION OF THE 9000SE PCM SIMULATOR FOR SIMULATION OF PCM DATAConell, David; Terametrix Systems International (International Foundation for Telemetering, 1991-11)This paper will discuss the needs and requirements of a PCM encoder data simulator. The 9000SE PCM encoder data simulator allows for the simulation of flight PCM data as well as bit error rate (BER) test patterns designed for link stress analysis. In addition, the open architecture of the 9000SE as an ISA bus device allows for the incorporation of the simulator into application specific realtime systems.
Aeronautical Channel Simulation in Network Simulators for Incorporation into OPNETDean, Richard; Zhang, Tianyin; Jaber, Nur; Morgan State University (International Foundation for Telemetering, 2010-10)This paper discusses channel simulation using OPNET Modeler in support of iNET. It shows how wireless communication is simulated, how to simulate the special aeronautical channel of iNET, and how to deliver the aeronautical channel, test article, and ground station as reusable components for future simulation. Network simulation is a critical tool for iNET and it enables design decisions that cannot be made analytically due to the complexity of the problem. This work addresses the incorporation of the aeronautical channel into the OPNET Modeler tool set as this piece of iNET is unique and is not available in OPNET Modeler.
