Navigation using Radio-Frequency Observables from LEO Constellations with Possible Aiding from an Inertial Navigation System

McLemore, Brian Kenneth 12 January 2023 (has links)
Analyses are performed on the potential of using radio-frequency signals from massive LEO satellite constellations. This work aids in the creation of a navigation system independent of current GNSS. A tightly-coupled carrier Doppler shift/INS filter is developed to determine the feasibility of using signals of opportunity from LEO satellites for navigation purposes. This portion of the work makes two major contributions to the field of satellite-based radio-navigation systems. The first contribution is an analysis that shows GNSS-like position accuracy is possible using only INS measurements and carrier Doppler shift from LEO communication constellations. The second contribution is that INS quality, signal availability, and constellation design can significantly impact the navigation accuracy of a carrier Doppler shift/INS Kalman filter. An analysis of the costs and benefits of using model replacement over a Markov model in the dynamic propagation step of a tightly-coupled carrier Doppler shift/INS Kalman filter is performed in the next part of this work. This portion of the work makes contributions to the field of satellite-based radio-navigation systems. The main contribution is an analysis that shows Gauss-Markov models can be used instead of model replacement without increasing navigation error. Next, a DOP analysis is developed for systems using pseudorange and carrier Doppler shift measurements in point-solution batch filters that do not rely on INS data or dynamic propagation. This section's contributions to the field of satellite-based radio-navigation systems include a combined pseudorange and carrier Doppler shift DOP analysis using a novel DOP metric and an example of how to use the DOP analysis to identify the constellation characteristics, such as alternating ascending and descending nodes, that the OneWeb constellation could change to increase navigation accuracy. / Doctor of Philosophy / This dissertation presents research on using large communication satellite constellations as an independent backup to GPS. Simulated data are used to study the feasibility and navigation accuracy of such a system. Also investigated are different implementations of the algorithms used to navigate. Finally, a general analysis is developed to quickly approximate the navigation accuracy of a system that uses multiple measurement types.

Sensor Package Analysis and Simulation for Direct Sensor-to-Satellite Links

Al-Saleh, Mohammad 19 January 2008 (has links)
This thesis investigates the design and the performance of low-power microsensors that communicate directly to a satellite or a constellation of satellites. Information is spread using pseudo noise (PN) or Barker codes. The sensors use a single circular microstrip patch element with a wide beamwidth or a miniature phased array antenna that continuously scans to access the satellite(s). The array beam is controlled with a beam-forming network (BFN), which contains 3 or 4-bit phase shifters, which can be made in micro-electro-mechanical systems (MEMS) or in monolithic microwave integrated circuits (MMIC). The antennas are designed using array simulation program called 'ARRAY' and the results are used in another simulation program called Advanced Design System (ADS) to simulate the whole sensor package that uses one of the antennas. The simulation results show that a sensor as small as 2.35 cm in diameter is able to send information with data rate of 1 kbps at bit error rate less than 10?? to low-earth orbit (LEO) satellites with a transmitted power of 27.5 microwatts (-15.6 dBm). / Master of Science

"The Case of Mary Phagan,'A Story About the Story of a Murder': Constructing a Crime"

Shelton, Regan Virginia 28 April 2000 (has links)
On April 27, 1913, the body of thirteen-year-old Mary Phagan was discovered in the basement of her workplace in Atlanta, Georgia. Over the course of the following two years, her employer, Leo Frank, would be tried and convicted for her murder. Another employee, Jim Conley, a black janitor originally implicated in the crime, provided the evidence used to convict Frank. In my thesis, I explain the multiple identities created to describe the victim and her accused murderer(s). Press reports, trial records, and secondary historical accounts of the crime all reveal a fascination with the young female victim and a desire to solve the mystery of her death. By examining personal identity as a cultural construction, I re-evaluate the manner in which we define and describe crime. Phagan's murder became a cautionary tale, a narrative of sexual danger within the model city of the New South. My thesis illustrates the importance of understanding murder as an event occurring within and shaped by a social context. The murder of Mary Phagan and the Frank case demonstrate how we ascribe meaning to tragic events and how variables such as race, class, gender, and age affect the outcome of criminal procedures. / Master of Arts

Lisboa menina e moça: a personificação da cidade nas letras de fado / Lisbon as a girl and young woman: personification of the city in the lyrics of fado

Casarini, Marcelo 23 April 2012 (has links)
A partir das letras de fado acerca da cidade de Lisboa cuja colheita, inédita, foi parte inicial desta investigação o presente trabalho procura mostrar de que modo a cidade de Lisboa é vista e representada por seus habitantes. A análise de um corpus de 183 canções que cantam a cidade enquanto tal (e não elementos dela: o castelo, o Tejo, bairros, telhados, personagens), revelam que Lisboa é quase sempre uma mulher. Em seguida, o presente estudo dedica-se a interpretar, utilizando como método o círculo filológico da estilística de Leo Spitzer, o fenômeno da personificação de Lisboa no fado, primeiro por uma perspectiva diacrônica e depois sincronicamente. Por último, dedica-se a revelar que tipo de mulher é Lisboa, e sua relação com as vendedoras ambulantes (varinas, saloias, minhotas) e meretrizes que historicamente frequentavam as ruas da cidade e hoje frequentam apenas o imaginário popular. E principalmente a relação de Lisboa-mulher com o mito da Maria Severa. / Based on the lyrics of fado for which there has been no previous research or collection into one study this thesis seeks to show how the city of Lisbon is seen and represented by its inhabitants. The analysis of a corpus of 183 songs that sing the city as such (and not elements of it: the castle, the Tagus, neighborhoods, roofs, characters), shows that Lisbon is most of the time portrayed as a woman. Subsequently, the present study interprets, using the \"philological circle\" proposed by Leo Spitzer as a method, the phenomenon of personification of Lisbon in fado, first by a diachronic perspective and then synchronically. Finally, it investigates what kind of woman Lisbon is, and its relationship with the female street vendors (varinas, saloias, minhotas) and harlots who historically inhabited the city\'s streets but today are present only in the imagination of its people. Particular attention is paid to the relationship between the Lisbon-woman and the myth of Maria Severa.

A recusa teimosa: ensaios sobre o pensamento conservador / The stubborn refusal: essays on conservative thought

Simões, Bruno Costa 01 July 2010 (has links)
O presente estudo parte da proposta de um pacto narrativo com o leitor, envolvendo uma dupla operação: renunciar, provisoriamente, o formato usual de uma tese dirigida contra ou a favor do pensamento conservador (sem perder de vista o posicionamento político e filosófico em questão), e assumir, enquanto isso, a complexidade da perspectiva de autores que se apropriaram e polemizaram questões políticas e temas filosóficos tendo em vista o seu tempo. Quanto ao gênero em questão, a proposta de desenvolver uma reunião de ensaios procura delimitar as configurações teóricas que permitiram o incremento de um pensamento conservador. A partir das leituras que Carl Schmitt e Leo Strauss estabeleceram sobre a filosofia de Thomas Hobbes, uma das principais problematizações tratadas aqui é a que vê na filosofia hobbesiana a fundação do liberalismo. Para tanto, a questão da adesão ou da separação entre a filosofia política e a filosofia natural torna-se bastante polêmica no tratamento que ambos os intérpretes dão a Hobbes. Como críticos dos rumos da política contemporânea, Schmitt e Strauss entenderam a instauração filosófica do racionalismo moderno como a base teórica que permitiu, a um só tempo, a consolidação de um Estado político que superou a ordem passada, o incremento de um regime absoluto de dominação da sociedade e a abertura que viabilizou, pelo desenvolvimento técnico da nova ciência da natureza e pelo rebaixamento moral da finalidade da vida humana, a ascensão liberal. Como uma tentativa de compreensão da força e das consequências que tais intérpretes tiveram, o presente estudo ainda explora uma recepção crítica brasileira da obra de Strauss que questiona e limita a interpretação da fundação hobbesiana do liberalismo. / This study proposes a narrative pact with the reader, involving a double operation: a temporary renouncement of the usual format of a thesis directed against or in favour of conservative thinking (without losing sight of the political and philosophical positioning in question), and assuming, meanwhile, the complexity of the perspective of authors who take political issues and philosophical subjects aiming at polemizing and debating problems that belong to their own times. As to the literary genre, the proposal of making up a set of essays aims to delimit the theoretical settings that enabled the development of a conservative thought. Considering the interpretations that Carl Schmitt and Leo Strauss set out concerning the philosophy of Thomas Hobbes, a major question treated here is that which sees the Hobbesian philosophy as the foundation of liberalism. For this purpose, the issue of adherence or separation between political philosophy and natural philosophy becomes quite provocative in the way both authors treat Hobbes. As critics of the contemporary political directions, Schmitt and Strauss consider the settlement of modern philosophical rationalism as the theoretical basis that made at the same time possible the consolidation of a political State that overcame the former order of politics, the instauration of an absolute regimen of domination of the society and, finally, the breach which, through the technical improvement of the new science of nature and the debasement of the moral purpose of human life, made the liberal ascension feasible. As an attempt to understand the strength and the consequences that such interpreters had, this study also explores the Brazilian critical reception of the works of Strauss, which discusses and delimits the interpretation of the Hobbesian foundation of liberalism.
