International Telemetering Conference Proceedings / October 13-16, 1986 / Riviera Hotel, Las Vegas, Nevada / The Experimental Flight Test organization of the Boeing Commercial Airplane Company has an onboard data reduction system known as the Airborne Data Analysis/Monitor System or ADAMS. ADAMS has evolved over the last 11 years from a system built around a single minicomputer to a system using two minicomputers to a distributed processing system based on microprocessors. The system is built around two buses. One bus is used for passing setup and control information between elements of the system. This is burst type data. The second bus is used for passing periodic data between the units. This data originates in the sensors installed by Flight Test or in the Black Boxes on the airplane. These buses interconnect a number of different processors. The Application Processor is the primary data analysis processor in the system. It runs the application programs and drives the display devices. A number of Application Processors may be installed. The File Processor handles the mass storage devices and such common peripheral devices as the printer. The Acquisition Interface Assembly is the entry point for data into ADAMS. It accepts serial PCM data from either the data acquisition system or the tape recorder. This data is then concatenated, converted to engineering units, and passed to the rest of the system for further processing and display. Over 70 programs have been written to support activities on the airplane. Programs exist to aid the instrumentation engineer in preparing the system for flight and to minimize the amount of paper which must be dealt with. Additional programs are used by the analysis engineer to evaluate the aircraft performance in real time. These programs cover the tests from takeoff through cruise testing and aircraft maneuvers to landing. They are used to analyze everything from brake performance to fuel consumption. Using these programs has reduced the amount of data reduction done on the ground and in many cases eliminated it completely.

International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California / The yawsonde is a device used at the U.S. Army Research Laboratory (ARL) to investigate the in-flight behavior of spinning projectiles. The standard yawsonde consists of a pair of solar cells and slits that respond to solar rays. The sun is used as an inertial reference to measure the pitching and yawing motions of the projectile. An FM telemetry package transmits the sensor data to a ground receiving station for analysis. The standard yawsonde package is housed in an M577-type artillery fuse body. The spinning motion of the projectile serves as the sampling rate for the measurements. When the spin rate is not significantly higher than the yaw rate, multiple sets of sensors must be used to effectively increase the sampling rate. The pinhole yawsonde sensor was developed for projectiles that require multiple sets of sensors in a very limited space. This pinhole yawsonde consists of a number of sensors located behind pinholes placed around the projectile's circumference. Since each pinhole makes a yaw measurement, many measurements, or samples, are taken with each projectile spin revolution. More pinhole sensors may be added to increase the measurement sampling rate. One application of this yawsonde is to aid in evaluating the performance of tactical devices and inertial systems onboard projectiles with limited space for instrumentation.

International Telemetering Conference Proceedings / October 17-20, 1994 / Town & Country Hotel and Conference Center, San Diego, California / The rapid technology growth in the aerospace industry continues to manifest itself in increasingly complex computer systems and weapons systems platforms. To meet the data processing challenges associated with these new weapons systems, the Air Force Flight Test Center (AFFTC) is developing the next generation of data acquisition and processing systems under the Advanced Data Acquisition and Processing Systems (ADAPS) Program. The ADAPS program has evolved into an approach that utilizes Commercial-Off-The-Shelf (COTS) components as the foundation for Air Force enhancements to meet specific customer requirements. The ADAPS program has transitioned from concept exploration to engineering and manufacturing development (EMD). This includes the completion of a detailed requirements analysis and a overall system design. This paper will discuss the current status of the ADAPS program including the requirements analysis process, details of the system design, and the result of current COTS acquisitions.

International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada / The technology growth in the Aerospace industry, as manifested and embodied in the current fighter technology, presents many challenges in the area of flight test and data processing. Past papers have delineated the concepts brought to bear in the design and implementation of the AFFTC’s latest generation of telemetry data systems in the Advanced Data Acquisition and Processing System (ADAPS) program. The current deployed system incorporates the planned approach of commercial-off-the-shelf (COTS) and government-off-the-shelf (GOTS) elements as basic to the system solution. The state of the program has advanced through full development, delivery and performance testing. The system is currently deployed in support of flight testing at Edwards AFB. This paper will present the status of the program.

International Telemetering Conference Proceedings / October 27-30, 1997 / Riviera Hotel and Convention Center, Las Vegas, Nevada / The growing need to transmit larger telemetry streams from the receiving site to the processor location over greater distances is requiring newer and more creative techniques. This paper reports efforts to use Asynchronous Transfer Mode (ATM) technology and inverse multiplexing to provide an economical system to interface telemetry streams into the public network for reliable transmission. Cost savings are available immediately for programs that are willing to meet the synchronization criteria today. Lab testing has shown the feasibility of using cost efficient techniques for data transmission. This document describes the investigation that is currently underway that could provide a significant change to the way telemetry data is transmitted from receiver sites to data processing sites. Instead of using dedicated lines with dedicated bandwidth regardless of the program being supported, the approach that has been tested in a lab environment would allow the dynamic allocation of bandwidth using ATM over a variety of carrier services. The combination of ATM and inverse multiplexing allows telemetry data rates above 1.5 Megabits per second (Mbps) to be transmitted over multiple T1 (1.544 Mbps) lines. Previously, the only choice when data rates exceeded 1.5 Mbps was to use an entire DS-3 (45 Mbps). Now it is possible to transmit intermediate sized data rates (1.5 to 8 Mbps) by bonding multiple T1s to provide the desired data throughput.

International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California / PC based instrumentation and telemetry processing systems are attractive because of their ease of use, familiarity, and affordability. The evolution of PC computing power has resulted in a telemetry processing system easily up to most tasks, even for control of and processing of data from a very complex system such as the Common Airborne Instrumentation System (CAIS) used on the new Lockheed-Martin F-22. A complete system including decommutators, bit synchronizers, IRIG time code readers, simulators, DACs, live video, and tape units for logging can be installed in a rackmount, desktop, or even portable enclosure. The PC/104 standard represents another step forward in the PC industry evolution towards the goals of lower power consumption, smaller size, and greater capacity. The advent of this standard and the availability of processors and peripherals in this form factor has made possible the development of a new generation of portable low cost test equipment. This paper will outline the advantages and applications offered by a full-function, standalone, rugged, and portable instrumentation controller. Applications of this small (5.25"H x 8.0"W x 9.5"L) unit could include: flight line instrumentation check-out, onboard aircraft data monitoring, automotive testing, small craft testing, helicopter testing, and just about any other application where small-size, affordability, and capability are required.

ITC/USA 2015 Conference Proceedings / The Fifty-First Annual International Telemetering Conference and Technical Exhibition / October 26-29, 2015 / Bally's Hotel & Convention Center, Las Vegas, NV / The aeronautical industries have been suffering financial cutbacks and the market has to face new challenges associated with new companies. Telemetry community has been facing the increase of the electromagnetic spectrum usage for a variety of applications (e.g. 4G), after all telemetry is everywhere. In view of these issues and focused on the inherent requirements of the Flight Test application, the IPEV R&D group proposes the iPCM Telemetry architecture as solution for the existing reliability and bandwidth issues associated with the telemetry link. In this article, as a proof-of-concept of the iPCM architecture, it has been performed an experimental assembly. The results demonstrate the iPCM's ability to regenerate corrupted data providing the required data integrity and reliability, besides the capability to dynamically select the FTI transmitted parameter list to optimize the bandwidth link.
