Phase I

Contract Number: N0429A-92-C-0094

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

Phase II

Contract Number: N00123-93-C-0253
Start Date: 5/26/1993    Completed: 6/1/1995
Phase II year

The TACTS/R-Cubed Transponder shall be a design that combines the electrical functions of the AIS Transponder assembly, AIS Digital Interface Unit (DIU), and R-Cubed AN/URY-3 into a single, multi-functional unit. The design of the TACTS/R-Cubed Transponder is to yield a fully transparent Transponder which will be mechanically compatible with an F18 internal package and pod configuration, and fully compatible with an F18 internal package and pod configuration, and fully compatible with existing R-Cubed and TACTS/ACMI based ranges. This unit will require no modifications to existing TACTS/ACMI ground systems. Specification NAWCWPNS-RE-EL-947-92, dated 27 May 1992, will be used as a goal for the electrical and functional requirements for the R-Cubed portion of the transponder. Specification Number SP494-IC (System Specification for Aircraft Instrumentation Sub-System, P-4A AIS), dated 20 April 1982, will be used for the electrical and functional requirements for the TACTS portion of the transponder. Functions of the Transponder which are selectable, will be switched via a mutually agreed upon uplink message command. Non-Volatile Memory (NVM) will be provided in the TACTS/R-Cubed Transponder to store and use the last used transponder format after power down and power up. A scanning capability will be provided which is activated after a time interval where the TACTS/R-Cubed transponder has not received a message or has not detected frequency use at the frequency currently selected. The mechanical design requirements must satisfy both the F18 internal package and pod configurations.
