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 / Through the use of early iNET-prototype IP Transceiver technology, Kawasaki Heavy Industries, Ltd. (KHI) has been able to communicate with flight test vehicles during a recent research program. This technology provides a two-way high-capacity communication that has not been achieved with conventional telemetry and can be used not only for flight testing, but also for rescue work. KHI has been authorized to use S-band IP Transceivers since last year in Japan, and various communication tests have been performed. This paper describes Japan's first simulation of an iNET RF network which incorporated testing that performed data backfill, voice communication and video transmission. A data backfilling test was performed using retransmit of lock-off data (which is lost as the aircraft maneuvers) on command from the ground station. Moreover, a tethered aerostat is considered a very useful communication relay platform in the event of a large-scale disaster which results in the destruction of infrastructure. Also, the silence of an aerostat can be very important for search and rescue work.

Thesis (MScEng (Electrical and Electronic Engineering))--University of Stellenbosch, 2009. / ENGLISH ABSTRACT: Aerostats and Stratolites could play a major role in expanding current satellite and other technologies in the near future. A study was made on the development of aerostat platforms and the current state of Stratolite development. The aim was to develop an airship system that is capable of maintaining a specific position regardless of the presence of wind. The various applications of such a geostationary platform are discussed. A dynamic model of an airship was developed and a simulation was implemented in software. This was done to study the possibility of developing aerostats like these. A tethered airship system was developed and built to demonstrate that it is possible to control the position of an airship. The airship system uses current technology in an unique combination to fulfil the requirement of remaining stationary despite the influence of wind. Various control system design techniques were used to implement the controllers. Linear models of the airship system were identified practically and used to design the controllers. The controllers were tested in simulation as well as practically and the results of these tests are given. It was concluded that there exists potential for the development of Stratolite systems, although there exists a fair amount of challenges and obstacles that would need to be overcome before this technology could be implemented. / AFRIKAANSE OPSOMMING: Aerostats en Stratolites kan ’n besondere rol speel in die uitbreiding van huidige sateliet- en ander aardwaarnemingstoepassings. ’n Studie is gemaak oor die ontwikkeling van Aerostat platforms en die huidige stand van Stratolite ontwikkeling. Die mikpunt was om ’n lugskipstelsel te ontwikkel wat in staat is om ’n spesifieke posisie te handhaaf ten spyte van die invloed van wind. Die verskeidenheid van toepassings, waarvoor so ’n geostasionêre platform gebruik kan word, word genoem. ’n Dinamiese model van ’n lugskip is ontwikkel en die stelsel is in sagteware gesimuleer. Dit is gedoen om die moontlikheid te ondersoek om sulke Aerostats in die toekoms te ontwikkel. ’n Lugskipstelsel, wat aan die grond geanker word met ’n kabel, is ontwerp en gebou. Die stelsel is gedemonstreer en daar is bewys dat dit moontlik is om die posisie van die lugskip te beheer. Die lugskip gebruik huidige tegnologie wat in ’n unieke kombinasie saamgevoeg is om te illustreer dat dit moontlik is vir die lugskip om stasionêr te bly ten spyte van wind. Verskeie beheerstelsels ontwerptegnieke is gebruik om die beheerders mee te implementeer. Lineêre modelle van die lugskip is prakties geïdentifiseer en is gebruik om die beheerders te ontwerp. Die lugskip se beheerders is in simulasie sowel as prakties getoets en die resultate van hierdie toetse word gegee. Die projek bevestig dat daar ’n potensiaal bestaan vir die praktiese ontwikkeling van Stratolite stelsels. Daar is egter ’n hele paar uitdagings en probleme wat eers uit die weg geruim sal moet word, voordat hierdie tegnologie ’n alledaagse werklikheid sal word.

Problema – Lietuvoje nėra sukurtos laisvojo aerostato pilotų rengimo pagal Pasaulinės aviacijos federacijos reikalavimus ir Europos Komisijos reglamentą. Tyrimai Lietuvos oro balionų sporto organizacijose parodė, kad būtina sukurti tobulesnį oro pilotų rengimo modelį, kuris atitiktų Pasaulinės aviacijos federacijos reikalavimus ir Europos Komisijos reglamentą; būtina tobulinti oro pilotų (pradedant moksleiviais ir baigiant pageidaujančiais pagyvenusiais žmonėmis) rengimo sistemą bei didinant šio sporto masiškumą plėsti Lietuvos oreivių draugijos klubų ir kitų padalinių steigimo geografiją. Darbo tikslas – sukurti Lietuvos laisvojo aerostato pilotų rengimo modelį. Objektas – Lietuvos laisvojo aerostato licencijuotų pilotų rengimo modelis Darbo uždaviniai: 1. Apžvelgti specialistų kompetencijų ir laisvojo aerostato licencijuotų pilotų rengimo teorinius aspektus. 2. Sukurti laisvojo aerostato piloto kompetencijų teorinį modelį. 3. Parengti tyrimo metodiką empiriniam tyrimui ir atlikti anketavimą Lietuvos oro balionų sporto organizacijose. 4. Pagrįsti laisvojo aerostato licencijuotų pilotų rengimo modelį. Tyrimo metodai: mokslinės literatūros šaltinių analizė, anketinė apklausa bei statistinė duomenų analizė. Darbas susideda iš trijų dalių. Pirmoje pateikta literatūroje paskelbtų teorinių aspektų apie kompetencijas ir jų modelius lyginamoji analizė bei sukurtas laisvojo aerostato pilotų licencijuotų pilotų kompetencijų teorinis modelis. Jame yra keturios sudėtinės dalys: greta...

Investigations of Lithuanian air balloons sporting organizations have shown the need for improved air pilot training model that meets the requirements of the Federation Aeronautique Internationale (FAI) and European Union standarts and directives and the need to improve pilots (starting with students and ending with elderly people) training system and increase Lithuania ballooning Society by enlarging it‘s geography. The aim – to create the model of an unrestricted aerostat pilots training in Lithuania. The object - model of licensed unrestricted aerostat pilots training in Lithuania The goals: 1) Review the professional competence of specialists and licensed unrestricted aerostat pilot in theoretical aspects. 2) Create theoretical model of unrestrictedaerostat pilot‘s competencies. 3) To prepare research methodology for empirical investigation and create questionnairy for Lithuanian hor air balloon sport organizations. 4) Substantiate the training model of licensed unrestricted aerostat pilots. Research methods: scientific literature analysis, questionnaire survey and statistical data analysis. The work consists of three parts. First is comparative analysis of theoretical aspects about the competencies and their models published in the literature... [to full text]
