International Telemetering Conference Proceedings / October 21, 2002 / Town & Country Hotel and Conference Center, San Diego, California / What do you do when your downlink telemetry needs outstrip your downlink bandwidth capability? The telemetry needed to support construction and operation of the largest, most complex engineering project ever undertaken, the International Space Station (ISS), already requires utilization of the full capacity of the downlink S-band capacity, yet there are additional systems and capabilities still to be added by NASA and the International Partners. The ISS Command and Telemetry Team has developed a method of swapping packets of telemetry that are intended for special operations, while simultaneously sending essential systems telemetry and less critical telemetry that is needed on a continuous basis. To support this attempt to “make available all of the data at least some of the time” the team developed concepts for grouping telemetry into families that would always be selected as a group and then created a set of metadata associated with these groups. This metadata is pre-defined to support automated selection and scrubbing of telemetry to correspond to major upgrades in the command and control software for the ISS. The new process will at least double the effective S-band downlink bandwidth. It will also provide automated selection, scrubbing, reporting and verification of telemetry selections.

International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California / An S-band telemetry transmitter has been developed for Expendable Launch Vehicles (ELV's) that can downlink data through NASA's Tracking and Data Relay Satellite System (TDRSS). The transmitter operates in the 2200 to 2300 MHz range and provides a number of unique features to achieve optimum performance in the launch vehicle environment: · Commandable QPSK or BPSK modulation format. · Data rates up to 10 Mbps. · Commandable concatenated coding provides superior link performance. · Premodulation filtering produces excellent spectral containment characteristics. · Phase noise of less than 3 degrees rms is maintained through launch and ascent vibration profiles. · A 30 watt nominal RF output power provides a robust RF link. · Two RF antenna output ports with commandable selection of all power out to either port or power split evenly between ports. · Operating modes and conditions of the unit can be monitored through a number of bilevel and analog outputs. · A ruggedized mechanical design provides a reliable communications link for launch vehicle environments.

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 / This paper looks at the migration paradox from a holistic perspective, revisits the Smarter Antenna concept and looks for synergetic solutions. The architecture presented also builds on the momentum of the relentless migration to network technology (that has already transformed telemetry data centers) and pushes it to the vehicle. The results are reduced costs and exciting new functionality, such as better situational awareness for mission conduct and range safety. Spatial and temporal domains are harnessed as aggressively as the frequency domain to enable denser spectral utilization and other exciting benefits. Imagine a Test Range no longer reliant on tracking systems (almost)!

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 / A new advanced 2.4 meter telemetry tracking antenna system allows for successful autotracking of high dynamic targets. The system is designed to work at C, S, and L bands. One of these systems at L/S-band was recently implemented and tested in the field. The testing included tracking aircraft during maneuvers such as rolls, spins, and antenna tower fly-by at high rates of speed. This paper examines test results and some of the features of the new system that allow for continuous tracking.

International Telemetering Conference Proceedings / October 21, 2002 / Town & Country Hotel and Conference Center, San Diego, California / Recent changes in spectrum availability as well as higher demands for spectrum have motivated the development of telemetry transmit systems capable of fully operating over both L and S telemetry bands. However, enabling operation within these two bands poses new problems in system design. This paper presents a prototype system capable of operating between 1.4 and 2.4 GHz, which supports continuous phase modulation (CPM) waveforms such as pulse code modulation (PCM), frequency modulation (FM), and shaped offset quadrature phase shift keying (SOQPSK). The system architecture is detailed, and the prototype performance is discussed.

Thesis (MMus (Music))--University of Stellenbosch, 2010. / AFRIKAANSE OPSOMMING: Die Kersfeesorkeste is ‟n Christelike tradisie binne die Kleurling-gemeenskap van die Wes-Kaap wat dissipline en goeie waardes by lede van hierdie gemeenskap inboesem en musiek in voorheen benadeelde en minderbevoorregte sektore van die samelewing bevorder. Die geskiedenis en agtergrond van die Kersfeesorkeste is soortgelyk aan dié van die Kaapse Klopse en die Maleierkore, wat veral prominent na vore kom tydens die Kersfees- en Nuwejaarsfeestelikhede in die Kaap. Alhoewel hierdie drie groepe ‟n nou verbintenis tot mekaar het en dikwels deur die publiek saamgroepeer word, funksioneer hulle onafhanklik van mekaar en is daar beduidende verskille in kultuur, repertoire, kleredrag, organisatoriese struktuur en samestelling. Hierdie studie fokus op die Perseverance Kersfeesorkes en ondersoek dié orkes in sy vele fasette binne die raamwerk van wat in die musiekwetenskap deesdae “gemeenskapsmusiek” genoem word. Die kenmerke van die begrip “gemeenskapsmusiek”, soos dit in die laaste 15 jaar in ander lande geformuleer is, word aan die hand van die Perseverance Kersfeesorkes getoets om uit te vind of die Perseverance Kersfeesorkes as ‟n voorbeeld van gemeenskapsmusiek beskou kan word en, omgekeerd, of die begrip “gemeenskapsmusiek” aan die hand van hierdie geval in alle opsigte gepas is of dalk aangepas moet word. / ENGLISH ABSTRACT: Christmas Bands are a Christian tradition within the Coloured community of the Western Cape that instils discipline and values amongst members of this community and promotes music within previously disadvantaged and under-privileged sectors of society. The history and background of the Christmas Bands is similar to that of the Cape Minstrels and Malay Choirs, who are very prominent during the Christmas and New Year festivities in the Cape. Although these three groups have a close connection they function independently of each other. There are significant differences amongst these groups in respect of culture, repertoire, uniform, organisational structure and composition. This study focuses on the Perseverance Christmas Band and examines this band in all its different facets within the framework of what, in current musicological terminology, is called “community music”. The characteristics of the concept of community music, as they have been formulated in other countries over the last 15 years, are tested against the Perseverance Christmas Band to determine whether the Perseverance Christmas Band should be understood as a example of community music and, vice versa, whether the concept of community music itself is valid when measured against the Perseverance Christmas Band or whether it needs adjustment or expansion.

The objective of the proposed research is to create new reconfigurable RF and millimeter-wave circuit topologies that enable significant systems benefits. The market of RF systems has long evolved under a paradigm where once a system is built, performance cannot be changed. Companies have recognized that building flexibility into RF systems and providing mechanisms to reconfigure the RF performance can enable significant benefits, including: the ability support multiple modulation schemes and standards, the reduction of product size and overdesign, the ability to adapt to environmental conditions, the improvement in spectrum utilization, and the ability to calibrate, characterize, and monitor system performance. This work demonstrates X-band LNA designs with the ability to change the frequency of operation, improve linearity, and digitally control the tradeoff between performance and power dissipation. At W-band frequencies, a novel device configuration is developed, which significantly improves state-of-the-art silicon-based switch performance. The excellent switch performance is leveraged to address major issues in current millimeter-wave systems. A front-end built-in-self-test switch topology is developed to facilitate the characterization of millimeter-wave transceivers without expensive millimeter-wave equipment. A highly integrated Dicke radiometer is also created to enable sensitive measurements of thermal noise.

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 reports the analysis of L-band channel sounding experiments conducted along the flight line at Cairns Army Airfield, Ft. Rucker, Alabama. Propagation data from multiple antennas on a helicopter to multiple receiving antennas on the ground are used to compute power delay profiles. Analysis of the results reveals delay spreads of the multipath channels between 200 ns and 400 ns, with the longer delay spreads resulting when using a receive antenna with lower gain and higher sidelobe levels. The data also shows that on average, diversity signaling from three aircraft-mounted antennas can lead to gains in signal-to-noise ratio of approximately 13 dB, with the gain dependent on the multipath characteristics observed by the ground antenna.
