International Telemetering Conference Proceedings / October 17-20, 1994 / Town & Country Hotel and Conference Center, San Diego, California / This paper describes a method for determining high resolution time, space, and position information for a test range flight vehicle using four tracking receivers. Equipped with GPS time systems, each receiver records the exact time at which a time marker embedded in the transmitted TM data stream is received. With this information, the time difference of arrival for the time markers at three of the receivers can be calculated referenced to the fourth. Using this time difference, the position of the transmitter can be determined. The accuracy with which the received signal time delay can be calculated depends on the accuracy of the GPS time system at each receiver. The effect of time accuracy on positional resolution is evaluated.

International Telemetering Conference Proceedings / October 22-25, 2001 / Riviera Hotel and Convention Center, Las Vegas, Nevada / The Range Instrumentation and Control System (RICS) is a network of personal computers (PCs), routers, and switches designed to transport time-space-position information (TSPI) and/or other data between multiple Test Sites and data reduction facilities. The typical use of RICS will be the transport of TSPI data from a System Under Test (SUT) to a Focus Site for real-time display and post-mission analysis of the data. This capability will be expanded to include the transport of telemetry (TM), video, and communications data via the RICS. This paper will discuss the overall hardware design of the RICS. It will further describe the programmatic issues encountered during the implementation phase of the RICS project. The paper will describe the initial design criteria, the selection of hardware to implement the design, problems encountered with the implementation of the hardware, solutions and workarounds to the problems encountered, and lessons learned during the entire process.

International Telemetering Conference Proceedings / October 18-21, 2004 / Town & Country Resort, San Diego, California / Joint Advanced Missile Instrumentation (JAMI), a Central Test and Evaluation Investment Program (CTEIP) initiative, is developing advanced telemetry system components that can be used in an integrated instrumentation package for tri-service small missile test and training applications. JAMI demonstrated significant improvement in the performance of low-cost Global Positioning System (GPS) based Time-Space-Position Information (TSPI) tracking hardware that can be used for world-wide test and training. Acquisition times of less than 3 seconds from a cold start and tracking dynamics to over 60 Gs were demonstrated. The design of a programmable Flight Termination Safe and Arm device has been completed. High dynamic testing results of GPS and Inertial measurement Unit (IMU) devices and problems encountered are discussed. Actual testing data will be compared with the original system design requirements. Integration of the JAMI components into weapon systems is now underway. This paper discusses the progress of the program during the past year and the efforts planned for the final year of 2005.

International Telemetering Conference Proceedings / November 04-07, 1991 / Riviera Hotel and Convention Center, Las Vegas, Nevada / The Global Positioning System of satellites and pseudosatellite ground stations (GPS) is designed to provide very accurate Time, Space, and Position Information throughout the entire world. It is also being used to provide such information to unmanned vehicles operating on test ranges throughout the United States, as a replacement/ adjunct for tracking radar as well as a form of guidance. What is proposed in this paper, for which a patent has been applied, is that the existing L-Band RF link carry command information, when required, as well as TSPI information.

ITC/USA 2011 Conference Proceedings / The Forty-Seventh Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2011 / Bally's Las Vegas, Las Vegas, Nevada / This paper describes a short distance telemetry network which measures and relays time, space, and position information among a group of ground vehicles. The goal is to allow a lead vehicle to be under human control, or perhaps controlled using advanced autonomous path planning and navigation tools. The telemetry network will then allow a series of inexpensive, unmanned vehicles to follow the lead vehicle at a safe distance. Ultrasonic and infrared signals will be relayed between the vehicles, to allow the following vehicles to locate their position, and track the lead vehicle.

International Telemetering Conference Proceedings / October 29-November 02, 1990 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Global Positioning System (GPS) translator signals have been used to track U.S Navy Trident missile test launches for the past 15 years. Absolute position accuracies of better than 20 meters in real-time and 8 meters in post mission have been consistently demonstrated. Flight qualified GPS translators 40 cubic inches in size have been developed for the U.S. Army Exoatmospheric Re-entry Vehicle Interceptor Subsystem (ERIS) program and are currently available for use by U.S. and allied government test ranges. More widespread use of GPS translators is constrained, however, by the great expense and size of the custom ground equipment currently used to acquire GPS translator signals and compute the position and velocity of the vehicle. To address this problem, the U.S. Air Force Western Space and Missile Center (WSMC) placed 3S under contract to design a lower-cost GPS translator processor based mainly on using commercial telemetry equipment. This paper describes how a working prototype was constructed to demonstrate the feasibility of the Translator Record and Interface System (TRIS). This prototype shows that TRIS can be built from a combination of commercially-available telemetry equipment, GPS equipment developed for the U.S. Air Force Range Applications Joint Program Office (RAJPO), and a few elements of custom equipment.

International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, Nevada / The Western Aeronautical Test Range (WATR) operates the ground stations for research vehicles operating at the NASA Dryden Flight Research Center (DFRC). Recently, the WATR implemented a new system for distributing Time, Space, and Position Information (TSPI) data. The previous system for processing this data was built on archaic hardware that is no longer supported, running legacy software with no upgrade path. The purpose of the Radar Information Processing System (RIPS) is to provide the ability to acquire TSPI data from a variety of sources and process the data for subsequent distribution to other destinations located at the various DFRC facilities. RIPS is built of commercial, off the shelf (COTS) hardware installed in Personal Computers (PC). Data is transported between these computers on a Gigabit Ethernet network. The software was developed using C++ with a modular, object-oriented design approach.

International Telemetering Conference Proceedings / October 22-25, 2001 / Riviera Hotel and Convention Center, Las Vegas, Nevada / A flexible, modular method is needed to connect test range data systems to central real-time computer networks. This is achieved by the development of a real-time, networked, VME-based range interface system. Flexibility is achieved by a modular hardware and software design. The modular hardware consists of standard network interfaces, COTS VME interfaces, and a VME single board computer (with an onboard PCI bus). The modular software is implemented in C++ using the VxWorks real-time operating system. This paper describes the conceptual design and development of the Modular Range Interface (ModRI).
