THE APPLICATION OF DIGITAL DEMODULATION TECHNIQUE FOR FREQUENCY MODULATION SIGNAL IN TELEMETRY RECEIVER

Peng, Song, XiaoLin, Zhang, Xue, Cao, Xia, Qi 10 1900 (has links)
International Telemetering Conference Proceedings / October 18-21, 2004 / Town & Country Resort, San Diego, California / Combined with an example of digital telemetry receiver design, this paper mainly discusses the application of software radio in telemetry receiver. The paper begins with an introduction of applying high efficiency digital filter and math analysis in quadrature digital frequency modulation and demodulation to digital frequency conversion technique. Next, Simulink/Matlab is used to simulate digital telemetry receiver. The method of simulation, analysis and calculation of performance and result of simulation are all available. In the end, the paper discusses digital telemetry receiver design and implement by making use of software radio technique, the circuits apply HSP50214 chip of Intersil Co., CPLD implements of Altera Co. and PC Bus. The sample is an expansion card for personal computer. Result of test, performance of the receiver and conclusion are given out, which show fine performance of receiver and can be apply to practice. The lever of this technology has reached first class in the world.

A COMPACT, LIGHTWEIGHT, LOW POWER, MULTI-FUNCTION TELEMETRY RECEIVER/COMBINER SYSTEM PROVIDES "HANDS OFF" AUTOMATION FOR SYSTEMS COST REDUCTION

O'Cull, Douglas C. 10 1900 (has links)
International Telemetering Conference Proceedings / October 17-20, 1994 / Town & Country Hotel and Conference Center, San Diego, California / With the increased concerns for reducing cost and improving reliability in today's telemetry systems, many users are employing simulation and automation to guarantee reliable telemetry systems operation. This places an increased demand on the remote capabilities of the equipment used in the telemetry system. Furthermore, emphasis has been placed on the ability to decrease the space and power consumption of the telemetry system to facilitate transportability of the a single telemetry system to multiple sites. Finally, today's telemetry systems demand that all equipment provide multiple functions to provide the maximum performance for the lowest system cost.

Design and Performance of Card Level Telemetry Receivers and Combiners

O’Cull, Douglas 10 1900 (has links)
International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California / This paper will discuss the design and performance of card level telemetry receivers and combiners. This will include products that have been designed to operate in compact computer controlled environments such as VME chassis, VXI chassis and personal computers using ISA buses. The paper will discuss design considerations required to overcome limitation of this environment such as noise and space. The paper will also discuss the performance of a telemetry receiver and combiner in this environment. This will include performance test results such as bit error rate test, phase noise measurements and combiner improvement measurements. Finally, the paper will discuss typical applications of card level telemetry receivers and combiners.

PREPARING A COTS GROUND TELEMETRY RECEIVER FOR USE IN THE INTERNATIONAL SPACE STATION

Champion, James 10 1900 (has links)
International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Within the industry, telemetry receivers are used in ground-based telemetry receiving stations to receive telemetry data from air or space-based sources. Equipment for the typical telemetry application is widely available. But when requirements create the need for a space-based telemetry receiver to uplink data from the ground, what are the choices for equipment? In such situations, adapting COTS equipment may present the only solution to meet delivery and budgetary constraints. The first part of this paper provides technical and contractual points a COTS supplier needs to consider when bidding on a COTS contract. The second part of this paper covers a project concerned with modification of a general-purpose ground telemetry receiver for use on the International Space Station. The information within the paper is useful to other engineers and companies considering contracts to modify COTS equipment for use on Shuttle or other space-based projects.

An Open Systems Architecture for Telemetry Receivers

Parker, Peter, Nelson, John, Pippitt, Mark 10 1900 (has links)
An open systems architecture (OSA) is one in which all of the interfaces are fully defined, available to the public, and maintained according to a group consensus. One approach to achieve this is to use modular hardware and software and to buy commercial, off-the-shelf and commodity hardware. Benefits of an OSA include providing easy access to the latest technological advances in both hardware and software, enabling net-centric operations, and allowing a flexible design that can easily change as the needs of customers may change. This paper will provide details of an OSA system designed for a telemetry receiver and list the benefits of OSA for the telemetry community.

FLEXIBLE NETWORK TRANSCEIVER NEXT GENERATION TELEMETRY NETWORKING

Brown, K. D., Klimek, John 10 1900 (has links)
ITC/USA 2005 Conference Proceedings / The Forty-First Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2005 / Riviera Hotel & Convention Center, Las Vegas, Nevada / This paper describes the Flexible Telemetry Transceiver (FNT)-a modular, scalable, standards-based, software configurable, microwave wireless telemetry network transceiver. The FNT enables flexible, high-rate, long-range, duplex, network services across multipoint to multipoint wireless channel.
