Full textThe terrestrial microwave telemetry links show limitation due their inherent features concerning bandwidth availability, frequency allocation and range. Also it supports only one aircraft per test and the data acquisition capacity can be enhanced. Following the flight tests trends, it proposes a telemetry link based on satellite communications deployed by off the shelf equipments allowing advantages as bandwidth availability, multiple aircrafts telemetry and almost global range into the reliability standards. By simple equations and typical flight tests data it demonstrates the feasibility of the telemetry system proposed for time and costs reduction to optimize flight tests programs.

Full textSatellitkommunikation är en allmänt känd metod för att kommunicera med avlägsna eller katastrofdrabbade platser. Ibland kan kommunikationen vara en fråga om liv och död, och det är därför viktigt att den fungerar bra. För tvåvägskommunikation (som internet) är det nödvändigt att antennen på jorden pekar mot satelliten med ett pekfel som inte är större än några tiondels grader. Exempelvis finns det lagar i USA som förbjuder pekfel större än 0,5°. I vissa fall måste antennen på jorden röra sig medan satellitkommunikation upprätthålls. Sådana fall kan vara när antennen är monterad på ett fordon och antennen således måste kompensera för fordonets rörelse för att peka mot satelliten. Denna applikation av satellitkommunikation kallas Satcom on the Move(SOTM). Genom att konstruera en simulinkmodell av ett fullständigt SOTM-system, inklusive fordonsdynamik, satellitposition, signalbeteende, sensorer och ställdon, kan olika reglerstrategier jämföras. Denna avhandling jämför en H2 - och en LQG-regulator för ett statiskt fall, samt ett dynamiskt fall. Det statiska fallet utförs med en sökalgoritm (spiralsökning) som syftar till att hitta en specifik satellitsignal på kortast möjliga tid för ett givet initialt pekfel. Det dynamiska fallet utförs genom att låta det simulerade fordonet köra i slalommönster och på ojämnt underlag. Regulatorerna är designade baserade på modern kontrollteori. Slutsatsen av denna avhandling är att H2-regulatorn presterar något bättre i det statiska testfallet, medan LQG-regulatorn presterar något bättre i de dynamiska testfallen. Resultaten påverkas emellertid kraftigt av de designade reglerparametrarna, vilket innebär att jämförelsen inte nödvändigtvis är sann för kontrollerna, utan snarare förde specifika reglerparametrarna.

Full textLEO satellite constellations allow to connect isolated or mobile users to the Internet, when terrestrial solutions are too expensive or impossible to deploy. Using such constellations allow to connect these areas with transmission delays close to terrestrial delays, and then to use the classic transport protocols such as TCP. However, this environment brings new impairments such as variable delays and important error rate between the satellite and the ground receiver. To counteract this high error rate, reliability schemes are introduced on the link between the satellite and the ground user. However, these schemes have a negative impact on the transport protocol (TCP), mitigating the throughput, and which has not been deeply studied yet. In this thesis, we first understand the impact of the reliability schemes on the transport layer, and then propose solutions to improve the efficiency of the transmissions

Full textThis research describes and analyzes a United States Navy Satellite Communications (SATCOM) performance monitoring model in providing status information to a network monitoring console to support naval operations. The environment is characterized by potentially adverse conditions that affect satellite performance. Current SATCOM systems are unable to provide performance information to the network's performance monitor because they are not Simple Network Management Protocol (SNMP) enabled and not integrated into the routable network. A network monitoring model defined by sense, decide, and act is central to this study. It represents enhanced monitoring by the subscriber station's monitor console for naval shipboard operations. This model delivers operational and RF environmental information to the SNMP MIB environment so that commonly used SNMP agents can request and send information for sending proper messages to the network's performance monitoring system. The proposed solution is explored through analysis of existing monitoring models together with observations of a tactical networking field experiment, in which equipment at the edge of the network and subscriber's SATCOM terminal is monitored for gathering critical performance details.

Full textAfin de prédire l'affaiblissement sur la liaison montante à partir de celui sur la liaison descendante qui opère à une fréquence différente, un modèle de similitude en fréquence a été ajouté au modèle de prédiction. La séparation des effets (gaz, nuage, pluie) est réalisée par un réseau de neurones, puis chaque composante est transposée à la fréquence voulue grâce à des coefficients de similitude spécifiques. L'incertitude sur ces coefficients de similitude implique une gestion combinée des erreurs de prédiction et des erreurs dues à la similitude.
Le modèle de prédiction avec similitude en fréquence a été développé avec des mesures de l'affaiblissement des balises 20/30 GHz du satellite OLYMPUS et est ensuite testé avec des données récentes de l'expérience SYRACUSE3 20/44 GHz. Les premiers résultats de cette expérience concernant les statistiques à long terme de l'affaiblissement sont ensuite présentés et comparés aux modèles standard de l'ITU.
Afin de mieux comprendre le lien entre l'affaiblissement et ses causes physiques, une approche basée sur les propriétés multifractales de la pluie est ensuite présentée. En effet, l'analogie entre la pluie et la finance peut être étendue, car ces deux phénomènes sont liés à des processus turbulents et possèdent des propriétés d'invariance d'échelle intéressantes. Malheureusement, l'analyse multifractale directe des séries temporelles d'affaiblissement ne donne pas de résultats satisfaisants. L'analyse multifractale est donc appliquée dans un premier temps à des séries temporelles de taux de pluie. Une évaluation de l'effet de l'intermittence pluie-non pluie sur l'analyse multifractale montre qu'elle provoque une cassure des relations d'invariance d'échelle et peut biaiser considérablement l'estimation des paramètres. L'analyse multifractale est alors réalisée évènement par évènement, c'est-à-dire avec des séries temporelles ininterrompues. Les résultats montrent que la pluie peut être modélisée par un FIF (Fractionally Integrated Flux) auquel on applique un seuil afin de reproduire l'intermittence pluie-non pluie.
La modélisation multifractale de la pluie est ensuite utilisée afin de simuler une liaison Terre-Satellite et de générer des séries synthétiques d'affaiblissement par la pluie. L'analyse de ces séries simulées permet de mieux comprendre pourquoi l'affaiblissement est difficile à modéliser. En particulier, bien que le champ pluie soit multifractal, les séries temporelles d'affaiblissement ne présentent pas de propriétés d'invariance d'échelle stables et peuvent même présenter un redressement du spectre de puissance aux hautes fréquences. Ces résultats montrent que le redressement du spectre observé empiriquement n'est pas dû uniquement au bruit de scintillation.

The increasing need for timely information in any environment has led to the development of mobile SATCOM terminals. SATCOM terminals seeking to achieve high data-rate communications require inertial antenna pointing to within fractions of a degree. The base motion of the antenna platform complicates the pointing problem and must be accounted for in mobile SATCOM applications. Antenna Positioner Systems (APSs) provide Inertially Stabilized Platforms (ISPs) for accurate antenna pointing and may operate in either an open or closed-loop fashion. Closed-loop antenna pointing strategies provide greater inertial pointing accuracies but typically come at the expense of more complex and costly systems. This thesis defines a nominal two-axis APS used on an EHF SATCOM terminal on a 707 aircraft. The nominal APS seeks to accomplish mobile SATCOM using the simplest possible system; therefore, the system incorporates no hardware specific to closed-loop pointing. This thesis demonstrates that the nominal APS may achieve accurate antenna pointing for an airborne SATCOM application using a hybrid open/closed-loop pointing strategy. The nominal APS implements the hybrid pointing strategy by employing an open-loop pedestal feedback controller in conjunction with a step-tracking procedure. The open-loop feedback controller is developed using optimal control techniques, and the pointing performance of the controller with the nominal APS is determined through simulation. This thesis develops closed-loop step-tracking algorithms to compensate for open-loop pointing errors.
(cont.) The pointing performance of several step-tracking algorithms is examined in both spatial pull-in and tracking simulations in order to determine the feasibility of employing hybrid pointing strategies on mobile SATCOM terminals. Keywords: Mobile SATCOM, Antenna Pointing, Inertially Stabilized Platform, Two-axis Positioner, Linear Quadratic Gaussian Control, Nonlinear Optimization.
