Smart Modularized Advanced Reusable Telemeter (SMART)

Daniels, R. M., Sheaffer, D. A. 10 1900 (has links)
International Telemetering Conference Proceedings / October 26-29, 1992 / Town and Country Hotel and Convention Center, San Diego, California / The SMART (Smart Modularized Advanced Reusable Telemeter) is an advanced telemetry system. The SMART system enhances the quality of a weapon system by providing an adaptable built-in telemetry capability for the weapon. Existing weapon telemetry systems are centralized, separate components which require many fault-prone interconnections. This system reduces the number of interconnections and provides higher performance than current systems. The modular system uses a high data-rate serial data link that connects remote measurement modules located throughout the unit-under-test. A smart processor is used to analyze and compress data from the various modules prior to transmission, making more effective use of the telemetry bandwidth. The smart processing unit also adapts the measurement units for changing test conditions on-the-fly. The system will allow more complete testing of the weapon system and solve a broader range of problems. The goal of the SMART project is to utilize the most advanced technology to overcome the current design methodologies that have perpetuated shortcomings in present systems. This project is being conceptualized to encompass a broader range of telemetry applications beyond the present weapon systems at Sandia.

Automated Generation of Telemetry Formats

Jones, Charles H., Gardner, Lee S. 10 1900 (has links)
International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California / The process of generating a telemetry format is currently more of an ad-hoc art than a science. Telemetry stream formats conform to traditions that seem to be obsolete given today's computing power. Most format designers would have difficulty explaining why they use the development heuristics they use and even more difficulty explaining why the heuristics work. The formats produced by these heuristics tend to be inefficient in the sense that bandwidth is wasted. This paper makes an important step in establishing a theory on which to base telemetry format construction. In particular it describes an O(nlog n) algorithm for automatically generating telemetry formats. The algorithm also has the potential of efficiently filling a telemetry stream without wasting bits.

AN XML SCHEMA FOR AIRBORNE TELEMETRY BASED ON THE IRIG TMATS STANDARD

Scardello, Mike, Harris, Jim, Downing, Bob 10 1900 (has links)
International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, Nevada / XML is a simple and powerful way to handle on data transfers between organizations, applications and/or computer systems. Currently, there is a significant effort within NASA to transition to XML vocabularies as the means of exchanging electronic data. XML can provide a useful way to transfer telemetry attributes data between customers and systems. The current standard for airborne telemetry data description is the Telemetry Attributes Transfer Standard (TMATS). TMATS is a well-defined, structured specification that will map into XML extremely well. This makes XML an excellent choice to supplement TMATS for the interchange of telemetry attribute information. The Western Aeronautical Test Range (WATR) at NASA Dryden Flight Research Center (DFRC) is defining an XML Schema that will be used in support of the WATR Integrated Next Generation System (WINGS). This paper describes this work in progress.

EFFECTS OF MULTIPATH-INDUCED DELAY DISTORTION ON PCM/FM FOR ENCANISTERED MISSILES

Vines, Roger M. 10 1900 (has links)
International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Coupling a distortion-free telemetry signal from an encanistered missile by using a pickup antenna inside the canister can be difficult, because the RF energy leaving the missile antenna travels through the canister and is reflected and absorbed in a complex manner before being received by the pickup antenna. In this paper the distortion incurred by a PCM/FM signal is described and used to predict the resulting distortion on the video after demodulation. Effects on bit error rate are presented as a function of delay distortion and bit rate. A demonstrated method of receiving a relatively undistorted telemetry signal using a pickup antenna is described.

REMOTE TELEMETRY CONCEPTS

STIERS, R., LYDON, T. 11 1900 (has links)
International Telemetering Conference Proceedings / November 04-07, 1991 / Riviera Hotel and Convention Center, Las Vegas, Nevada / A Remote Telemetry Station (RTS) was developed to support Boeing’s requirement to relocate its flight test telemetry range away from Seattle, Wa. As requirements to relocate the test range were investigated high level requirements were documented and various approaches were evaluated. The end result of the analysis and requirements definition was the procurement of the Remote Telemetry Station (RTS). The RTS is capable of supporting many sites, tracking and receiving up to 1024 Kbits/sec of telemetry data, providing fully redundant two-way radio communication in the UHF and VHF bands, linking all the data back to Seattle and appearing transparent to the users. The RTS was designed and developed by a Boeing/Veda Incorporated team. The end result of this joint design and development effort is a system that meets all Boeing requirements in a highly integrated, extremely efficient, and very flexible package providing for growth through the year 2000.

A Small Telemetry System

Sanzhong, Li, Xianliang, Li, Qishan, Zhang 10 1900 (has links)
International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California / A small PCM telemetry system designed for the flight test telemetry task of a new rotorcraft is introduced in this paper. It can provide a flexible frame format which is completely set up by user in advance, to meet the requirements needed in different flight testing phases. In this telemetry system, the data are low in rate and volume but very valuable with stringent quality and transmission accuracy. Data encrypting and channel encoding techniques are employed to guarantee the quality and security of the data. The system architecture based on microprocessors is adopted in order to process the data flexibly. Real-time data processing, monitoring and post-flight analysis are performed by PC type computers. All key components of the system may be programmed. The cost of the total system integration is relatively reduced.

Using the Telemetry Attributes Transfer Standard

Takacs, Theodore, Jr. 10 1900 (has links)
International Telemetering Conference Proceedings / October 25-28, 1993 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Telemetry attributes are the detailed items of information needed for a receiving/processing system to acquire and process data from a given test item. There are currently as many different ways to describe telemetry attributes as there are different organizations which provide them (instrumentation groups and aircraft/missile manufacturers) and use them (telemetry processing systems/test ranges). The Telemetry Attributes Transfer Standard (TMATS) has been developed as a method of standardizing the transfer of telemetry attributes information. This paper describes the TMATS standard and discusses its purpose and application.
