International Telemetering Conference Proceedings / October 25-28, 1993 / Riviera Hotel and Convention Center, Las Vegas, Nevada / The Strategic Arms Reduction Treaty (START) introduces an important new element into the Mission planning and operation processes of the Western Range and its users. In the past, safe and successful completion of a ballistic or space operation was the primary mission of the Range. Under START, the Western Range has the added responsibility of playing a major role in the verification process necessary for a safe reduction of the world's ballistic nuclear weapons. This paper describes the impact of the Treaty on both the Western Range and its users while outlining how the Range has adapted to meet the challenges introduced by the Treaty.

International Telemetering Conference Proceedings / October 26-29, 1992 / Town and Country Hotel and Convention Center, San Diego, California / A Digital Output Recorder (DOR) system was developed by JAYCOR under contract to Defense Nuclear Agency (DNA) for the recording of high-speed digital data from test hardware exposed to radiation during an Underground Nuclear Test conducted at the Nevada Test Site (NTS) in 1991. Electronics hardware for the system is based on the well-supported Versa Module Europe (VME) bus which has become an industry standard for digital process and control systems. The system collects, identifies, and telemeters the data from several interfaces using the VME bus to a common data collection point above ground. The system was designed with built-in flexibility and expandability to meet digital data recording requirements on future underground tests (UGTs).

International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, Nevada / This paper describes the implementation of a Feher-Patented Quadrature Phase Shift Keying (FQPSK) waveform variant that reduces overall design complexity, which in turn results in a telemetry transmitter that provides all the benefits of the existing FQPSK-B waveform, in a 3.0 x 2.0 x 1.0 volume. This variant is referred to the as the FQPSK-JR version. This waveform differs from the “near constant” envelop response of the qualified Herley airborne FQPSK-B telemetry transmitter in terms of the time domain wavelet transition functions and the amplitude scaling term associated with those functions. The end result is a “constant envelop” design, which employs simplified antialias filtering and more efficient digital design techniques.

International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada / The telemetry system has been used in many important fields. Generally speaking, it’s easy to judge whether the system operation is successful or not. But when it is running normally, it is not easy to evaluate the medium state (between success and fail) of the telemetry system, likes a man’s spirit state. In this paper, a method with fuzzy theory is brought forward to evaluate the “Spirit State” of the telemetry system. This method can be used to evaluate the telemetry system, or to evaluate other important system states. By this method, the estimation to the mission will be very exact and reliable.

International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada / The 412th Test Wing, Range Division has developed an all-terrain van system to receive real-time telemetry and also to display the processed data for remote location flight-testing. The vans are refurbished Ground Launch Cruise Missile (GLCM), Launch Control Centers (LCC). The vans were a joint development effort between the Range and the Advanced Fighter Technology Integration (AFTI) program office. The van systems were specifically designed to support Ground Collision Avoidance System (GCAS) testing. However, the van systems have been successfully used to support other customers, with remote telemetry needs, due to the systems Commercial Off the Shelf (COTS) design. This document will describe the design, layout and rationale for the systems design. This paper will also provide the systems capabilities with top-level block diagrams.

International Telemetering Conference Proceedings / October 28-31, 1985 / Riviera Hotel, Las Vegas, Nevada / A key milestone for every telemetry design is that date when everyone agrees on a definition of the design requirements. Unfortunately, specifications often become obscured as test constraints change, additional requirements are uncovered, test objectives are more clearly defined, and budgets are cut in half. Historically, telemetry designs using technology, hardware, and philosophy that pre-date Christopher Columbus have caused obvious rigidity to the system design and its operation. Once completed, program managers become ruefully aware that these systems are difficult (if not impossible) to modify and are always very costly to change. Telemetry systems available today offer the flexibility necessary to accommodate a frequently changing measurement list. Not only can the measurement list be changed, it can be changed during the course of a test in progress. If requirements expand, hardware may be added. If the test is a non-destructive test, the system can be configured for use on future programs.

International Telemetering Conference Proceedings / October 30-November 02, 1989 / Town & Country Hotel & Convention Center, San Diego, California / Computer Sciences Corporation, Realtime Data Systems Center has developed, integrated, tested, and delivered several large telemetry systems to various ranges over the past eight years. One key to the success of these systems has been the ability to build on a software base to meet unique range processing requirements for aircraft, missiles, and related weapons systems. Reusable software means reduced procurement and life cycle costs. The ability to successfully reuse software for new systems with new requirements lies not only in the fundamentals of modular system design, but in the ability of the people to comprehend the design, and adapt the software to new requirements. As advanced telemetry processing needs meet reduced budgets, the successful systems integrator will be relying more and more on an ability to adapt existing systems to meet new challenges.

International Telemetering Conference Proceedings / October 30-November 02, 1989 / Town & Country Hotel & Convention Center, San Diego, California / The telemetry group has begun a new program in conjunction with Goddard Space Flight Center to investigate the possibilities of using parallel processing configurations for the real-time processing of Space Station data. In order to evaluate the potential configurations, a program based on using discrete-event simulation models is being used. This modeling software allows for generic configurations to be modeled and the relevant parameters to be modified to see the effects on performance. This paper represents a description of the work we will be undertaking over the next 18 months and the environment to be used in creating the simulation models at NMSU.

International Telemetering Conference Proceedings / October 30-November 02, 1989 / Town & Country Hotel & Convention Center, San Diego, California / This paper describes the changes in signal conditioning techniques used on flight test programs in recent years. Improved sensors require improved signal conditioning. Advanced distributed data acquisition systems, used on major flight test programs, move the signal conditioning closer to the sensor for improved performance and reduced wiring throughout the vehicle. These distributed systems use digital communication between the master controller and the remote conditioning units for improved accuracy and noise immunity. This requires sample- and-hold amplifiers, analog-to-digital converters, and serial encoder/decoders to be located at the signal conditioning location. The changes in signal conditioning designs are driven by the sensors, the architecture of the data acquisition systems, and by vehicle designs (smaller aircraft, smaller missiles, composite structures, and hypervelocity vehicles). A look at the signal conditioning technology employed in many of these systems as well as what is anticipated in the future is described in this paper.

International Telemetering Conference Proceedings / October 17-20, 1988 / Riviera Hotel, Las Vegas, Nevada / The evolution of telemetry ground station systems over the past twenty years has tracked the evolution of the mini-computer industry during that same time period. As the various mini-computer vendors introduced systems offering ever increasing compute power, and ever increasing capabilities to support multiple simultaneous users, the high end of the telemetry ground station systems offered by the industry evolved from single stream, single user, raw data systems to multi-user, multiple stream systems supporting real-time data processing and display functions from a single CPU or, in some cases, a closely coupled set of CPUs. In more recent years we have seen the maturation of networking and clustering concepts within the digital computer industry to a point where such systems coupled with current workstation technology, now permit the development of large telemetry ground station systems which accommodate large numbers of simultaneous users, each with his or her own dedicated computing resources. This paper discusses, at a hardware block diagram and software functional level, the architecture of such a distributed system.
