DUAL TRANSPONDER FOR RANGING AND DATA COMMUNICATION

Microcom will design a Dual Frequency Transponder which will be compatible with the requirements of both the Tactical Aircrew Combat Training System (TACTS) and the Mobile Sea Range (MSH) system. We will modify our existing R-Cubed Transponder (AN/URY-3) by adding an L Band Transceiver to provide the data relay link for TACTS ranges with a Transponder volume target goal of 108 cubic inches. We plan to combine as many functions as possible within the Transponder to eliminate duplication of circuitry. This will result in a smaller, lower cost, more efficient and reliable unit. Our goal is to produce a Dual Frequency Transponder with peak power outputs of 200 watts at 141 MHZ when used for MSR, and 25 watts at L Band when used for TACTS ranges. This Phase I study will provide an engineering analysis to determine the feasibility of adding an L Band Transceiver to the existing R Cubed Transponder design and will determine expected performance parameters for ranging accuracy, receiver sensitivity, and transmitter power output. Issues that will be addressed in the Phase I study will include performance, size and weight goals, environmental parameters, and initial board layouts. In addition to the engineering analysis, Microcom will prepare a design plan and submit a preliminary system design specification which will be the basis for development, test, and qualification of a Dual Frequency Transponder in the Phase II project.
