• AERIAL CABLE TEST CAPABILITY INSTRUMENTATION SUPPORT

      Stephenson, Henry B.; Newton, Henry L.; White Sands Missile Range (International Foundation for Telemetering, 1992-10)
      The U. S. Army is developing an aerial cable range for testing missile weapon system components and other DOD material. The main component of the aerial cable range will be a three-mile-long Kevlar cable, fully suspended between two mountains, with an elevation difference of 2450 feet. Test vehicles (targets, test platforms, and retrieval trolleys) will travel along the cable at different speeds and different altitudes that conform to different test requirements. The main electronic support system for the aerial cable range will be the Ground Command and Control System (GCCS). The GCCS is being designed to control targets, retrieval trolleys, test fixtures, and test platforms on the aerial cable range. The GCCS will control up to four vehicles on the aerial cable at the same time. In the long term, the goal is to control test vehicles of 20,000 pounds in weight and 550 knots/hour in speed. The initial capability will control targets and test platforms of 10,000 pounds, at speeds of up to 250 knots/hour. The GCCS will consist of: • Telemetry links to communicate to and from various vehicles • A position measuring system to determine the position of the vehicle on the aerial cable • A control system to generate all commands necessary to activate events in the airborne vehicles • An operator console The control room will have the capability to display the vehicle parameters, meteorological data, lightning prediction data, video and real-time simulation.
    • How The User Relates to a Large Range Telemetry System

      Chavez, Tomas; Strock, O. Jud; White Sands Missile Range; Loral Data Systems (International Foundation for Telemetering, 1992-10)
      The Telemetry Data Handling System (TDHS) at the Telemetry Data Center in White Sands Missile Range (WSMR), New Mexico, has been in operation since January 1990. It is one of the world's largest integrated range telemetry systems, and certainly the most versatile in weapons support capability. The system supports one of the world's busiest test ranges, serving all U.S. Military Services as well as NASA and others. This paper looks at the White Sands system from the user's view, examining the ways in which it is configured for several weapons tests in a typical day, and the way in which it can run foreground launch support and background pre-launch activities simultaneously. This system has grown in functional capability since its installation, both in hardware and in software. This paper analyzes that growth to see the reasons and methods. Also, near-term additional growth is addressed.
    • SALINAS PEAK TELEMETRY ACQUISITION SYSTEM

      Montano, William G.; Hernandez, Francisco Jr; White Sands Missile Range (International Foundation for Telemetering, 1992-10)
      The Salinas Peak location is ideal for a Telemetry Acquisition and Relay Station. The Telemetry facility consists of a new building and the Telemetry Acquisition System (TAS) from Atom Peak. Salinas Peak is located in the San Andres Mountains, 68 miles north west of the White Sands Missile Range (WSMR) launch complexes. Salinas Peak provides better coverage for all Range Telemetry (TM) missions, and has excellent line-of-sight to the launch areas, impact areas and the Telemetry Acquisition and Relay System (TARS) mobile microwave relay stations.

    • TELEMETRY TRANSMITTER ACCEPTANCE TESTING AT WHITE SANDS MISSILE RANGE

      Wyman, Richard J.; White Sands Missile Range (International Foundation for Telemetering, 1992-10)
      White Sands Missile Range (WSMR) is the largest overland test range, operated by the Department of Defense, in the United States. It encompasses approximately 4000 square miles of south-central New Mexico. WSMR supports various missile, weapons system, and instrumentation development tests of the Army, Navy, Air Force, NASA, and other agencies, and controls the airspace and electromagnetic (EM) radiation on and around WSMR. Due to the large number of users at WSMR, the EM spectrum has become increasingly crowded and EM radiation control has become extremely important. For this reason, WSMR Regulation 105-10 (Telemetry Radio Frequency (RF) Spectrum Utilization) was adopted and states that all TM transmitters proposed for use at WSMR must be approved. These transmitters are approved upon determination that they meet the requirements set forth in the current Range Commander’s Council (RCC) Inter-Range Instrumentation Group (IRIG) Document titled “Telemetry Standards”. (NOTE: This document will hereafter be referred to as RCC Document 106). This determination is performed by the White Sands Missile Range Director of Information Management (WSMR-IM) in the form of acceptance testing and analysis. This acceptance testing consists of the verification and analysis of the transmitter’s frequency stability, output power, and spurious and harmonic emission levels, in order to prevent EM interference between the many range users. The current test methodology will be explored in sufficient detail so that potential range users will know the procedures used to qualify TM transmitters for use at WSMR. Past methods and future testing considerations will also be briefly examined.
