    The problems discussed include that associated with the requirements process which leads to overspecification and an overly rigid approach to development, and a procurement system which is bloated and grossly inefficient. The bureaucracy in the DoD acquisition system has grown steadily from the 1960's to 1990's. Each problem encountered, and there have been serious ones, has resulted in the additi...

    Innovative field testing techniques are employed at Holloman Air Force Base to help the Global Positioning System (GPS) NAVSTAR Joint Program Office (JPO) test the Precision Lightweight GPS Receiver (PLGR). Characterizing the PLGR's accuracy in dynamic environments is of prime importance but testing also prescribes the evaluation of its ability to receive differential GPS corrections, real time, a...

    The handling of containers in terminals requires, in particular in the application of "chaotic storekeeping", optimal logistic organization-supported by technical and innovative methods. In this manner, it is possible to guarantee that the existing resources are used at maximal cost and time efficiency. The satellite supported DGPS location system represents a substantial contribution to this prob... View full abstract»

    Synthetic Aperture Radar (SAR) is an airborne (or spaceborne) radar mapping technique for generating high resolution maps of surface target areas including terrain. High resolution is achieved by coherently combining the returns from a number of radar transmissions. The resolution of the images is determined by the parameters of the emissions, with more data giving greater resolution. A requiremen... View full abstract»

    On February 10, 1993 an Air Force F-16 dropped an INS/GPS modified GBU-15 from an altitude of 35,000 feet and a downrange distance of 88,000 feet in adverse weather. The guided weapon impacted within 6 meters of the target, demonstrating the potential of INS/GPS technology to significantly improve air-to-surface munitions strategies and tactics. This landmark flight was successfully followed by fi... View full abstract»
