• Common Airborne Processing System (CAPS) 2.0: Data Reduction Software on a Personal Computer (PC)

      Hunt, Trent W.; TYBRIN Corporation; Eglin Air Force Base (International Foundation for Telemetering, 1997-10)
      CAPS 2.0 provides a flexible, PC-based tool for meeting evolving data reduction and analysis requirements while supporting standardization of instrumentation data processing. CAPS 2.0 will accept a variety of data types including raw instrumentation, binary, ASCII, and Internet protocol message data and will output Engineering Unit data to files, static or dynamic plots, and Internet protocol message exchange. Additionally, CAPS 2.0 will input and output data in accordance with the Digital Data Standard. CAPS 2.0 will accept multiple input sources of PCM, MIL-STD-1553, or DDS data to create an output for every Output Product Description and Dictionary grouping specified for a particular Session. All of this functionality is performed on a PC within the framework of the Microsoft Windows 95/NT graphical user interface.
    • Mission Integrated Decommutation and Analysis System (MIDAS): Extracting Data from Digital Tape Recordings on a PC

      This paper presents the Mission Integrated Decommutation and Analysis System (MIDAS), a multi-threaded, multi-processing application developed in Microsoft Visual C++ for Windows NT by the Air Force Development Test Center (AFDTC) Eglin AFB, Florida. The primary function of MIDAS is to support post-test processing of instrumentation data by decommutating, logging, and reporting MIL-STD-1553B or pulse code modulated (PCM) encoded data extracted from MARS-II digital tape recordings. MIDAS processes multiple data streams from a single recording, and can process multiple recordings in parallel. MIDAS also serves as a diagnostics tool for investigating data processing anomalies reported during normal production runs. MIDAS is part of an integrated suite of applications developed to provide AFDTC development test and operational test customers with quickly delivered, high-quality data products. Software development is underway to support the processing of Digital Data Acquisition and On-Board Recording Standard (DDAS) packetized telemetry data. DDAS is derived from the Consultative Committee for Space Data Systems (CCSDS) standard. [MARS-II is the digital acquisition and recording system supported by MIDAS. MARS-II was developed by DATATAPE, Incorporated, Pasadena, California. It records up to 20 gigabytes of mission data across as many as eight channels of MIL-STD-1553B or PCM encoded data. Digital recording technology provides an alternative to traditional analogbased telemetry ground systems.]

      In this paper, the Miniature Data Acquisition Transceiver System (Mini-DAT), a Type II PC-Card based data acquisition and transceiver system is described. The Mini-DAT was developed by ViaSat and is currently in use at the Air Force Research Lab (AFRL) at Eglin AFB. AFRL is investigating the use of this Industrial, Scientific and Medical (ISM) band system for data collection with advanced munitions. The Mini-DAT combines the advantages of PC-Card technology with an off the shelf interfacing and packaging approach to provide a large array of capabilities in a very small package. The system provides everything needed to collect analog, discrete and digital data, process the data and transfer the data in a wireless fashion using the latest license free spread spectrum modulation technology. The advanced design of the Mini-DAT allows for operation in harsh remote environments, collecting data unattended and accessed remotely. A graphical user interface (GUI) is provided via a Windows 3.x and 95 software package that can be easily customized for specific applications. The Mini-DAT provides fast and reliable error-free data transfer over the 2.4GHz ISM communication band. It operates over a shared 80MHz bandwidth, allowing multiple access of a number of portable units operating simultaneously in the same band.
    • Telemetry Definition and Processing (TDAP): Standardizing Instrumentation and EU Conversion Descriptions

      Campbell, Daniel A.; Reinsmith, Lee; Eglin Air Force Base (International Foundation for Telemetering, 1997-10)
      Telemetry format descriptions and engineering unit conversion calibrations are generated in an assortment of formats and numbering systems on various media. Usually this information comes to the central telemetry receiving/processing system from multiple sources, fragmented and disjointed. As present day flight tests require more and more telemetry parameters to be instrumented and processed, standardization and automation for handling this ever increasing amount of information becomes more and more critical. In response to this need, the Telemetry Definition and Processing (TDAP) system has been developed by the Air Force Development Test Center (AFDTC) Eglin AFB, Florida. TDAP standardizes the format of information required to convert PCM data and MIL-STD-1553 Bus data into engineering units. This includes both the format of the data files and the software necessary to display, output, and extract subsets of data. These standardized files are electronically available for TDAP users to review/update and are then used to automatically set up telemetry acquisition systems. This paper describes how TDAP is used to standardize the development and operational test community’s telemetry data reduction process, both real-time and post-test.

      The U.S. Air Force has developed GPS-based instrumentation systems to support both test and training activities. In support of recent large-scale exercises, interfaces were developed to employ existing test and training assets in a synthetic battlefield. The writers propose exploration of similar approaches to overcome the challenge of developing a common approach to test and training instrumentation.
