Abstract There has been a recent surge in interest for optical satellite communication (SatCom) utilizing lasers. It is clear to see why, as optical SatCom is capable of higher speed, lighter weight, higher directionality, and higher efficiency versus their radio-based counterparts. Research into optical SatCom has focused on devices operating in the short-wave infrared (SWIR), which is due to the maturity and commercial availability of such component’s thanks to significant development in terrestrial telecommunications networks. However, SWIR performs poorly in fog and heavy weather, prompting investigations into longer mid-wave and long-wave infrared bands for optical communication instead due to reduced atmospheric losses. This paper provides a comprehensive review of laser transmitters, detectors, and the science behind selecting longer wavelengths for optical SatCom to boost optical SatCom between ground stations and low earth orbit satellite constellations being deployed.

Abstract. The daily variability of the ionosphere can greatly affect HF or SATCOM communications. HF skywave operators plan frequency schedules months in advance, however, they also require daily knowledge of the ionospheric conditions in order to modify assignments. SATCOM operators also require daily information about the levels of scintillation, which are variations in phase, amplitude, polarisation and angle of arrival that can cause severe degradation of the received signal. Using a number of ionosonde measurements and geomagnetic and solar values, a Daily Ionospheric Forecasting Service (DIFS) has been developed, which provides HF and SATCOM operators with daily forecasts of predicted ionospheric conditions. The system uses in-house algorithms and an externally developed Global Ionospheric Scintillation Model (GISM) to generate HF and SATCOM forecasts. HF forecasts consist of a past summary and a forecast section, primarily displaying observed values and predicted categories for the Maximum Usable Frequency (MUF), as well as an Ionospheric Correction factor (ICF) that can be fed into the ionospheric propagation prediction tool, WinHF. SATCOM forecasts give predictions of global scintillation levels, for the polar, mid and equatorial latitude regions. Thorough analysis was carried out on DIFS and the results conclude that the service gives good accuracy, with user feedback also confirming this, as well.

The 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.

Satellite communication is a widely known method for communicating with remote or disaster-strickenplaces. Sometimes, thecommunication can be a matter of life and death,and it is thus vital that it works well. For two-way communication (such as internet) it is necessary for the antenna on Earth to point towards the satellite with a pointing error not larger than a few tenths of a degree. For example, regulations decided by the authorities in the U.S. forbid pointing errors larger than 0.5°. In some cases the antenna on Earth has to be moving while satellite communication is maintained. Such cases can be when the antenna is mounted to a vehicle, and the antenna thus has to compensate for the vehicle’s movement in order to point at the satellite. This application of satellite communication is called Satcom on the Move (SOTM). By constructing a Simulink model of an entire SOTM-system, including vehicle dynamics, satellite position, signal behavior, sensors, and actuators, different control strategies can be compared. This thesis compares the performance of an H2- and an LQG-controller for a static initial acquisition case, and a dynamic inertial stabilization case. The static initial acquisition case is performed with a search algorithm (SpiralSearch) aiming to find the satellite signalin the shortest possible time for a given initial pointing error. The dynamic inertial stabilization case is performed by allowing the simulated vehicle to drive in a slalom pattern and over uneven grounds. The controllers are designed based on modern control theory.The conclusion of this thesis is that the H2-controller performs slightly better in the static testcase,whereastheLQG-controller performs slightly better in the dynamic test cases. However, the results are greatly influenced by the tuning of the controllers, meaning that the comparison is not necessarily true for the controllers rather than the tuning parameters.
Satellitkommunikation 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.

L'accès à Internet par satellite permet de connecter des régions isolées de la terre ou des utilisateurs en mouvement, pour lesquels une solution terrestre peut s’avérer couteuse voire impossible. L’utilisation de constellations de satellite en orbite basse permet de transmettre avec des délais similaires à ceux des transmissions terrestres, permettant l’utilisation des protocoles de transport classiques comme TCP. L’utilisation d’un tel environnement engendre cependant des contraintes spécifiques à ce type de réseau, comme des délais de transmission variables et un important taux d’erreur, principalement lors de la traversée de l’atmosphère. Pour compenser ces forts taux de pertes, des mécanismes de fiabilisation doivent être introduit au niveau des couche basse. Ces mécanismes ont toutefois un impact négatif sur les performances des protocoles de transport, notamment TCP, limitant grandement le débit. Le but de cette thèse est de comprendre dans un premier temps les interactions entre les mécanismes de fiabilisation et les protocoles de transport, pour ensuite proposer des solutions permettant d’améliorer la qualité des transmissions
LEO 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

A method of generating constant envelope BPSK compatible modulation formats is described in which spectral containment is achieved via controlled phase rotations. These Shaped BPSK modulations can be considered BPSK/CPM hybrids. The instantaneous phase transitions of BPSK are tempered to become the continuous phase rotations of CPM. The SBPSK modulations described above are compared with classical BPSK as well as a Shaped BPSK modulation specified by the Joint Chiefs of Staff for use with Department of Defense 5kHz UHF SATCOM channels. It is shown that the use of SBPSK modulations can allow significant increases in the data transmission rate without exceeding the spectral "envelope" of a lower rate BPSK signal. Analysis also includes fractional out of band power curves for the modulated signals before and after transmission through a bandpass hard-limited channel. Equivalent SNR's are generated to quantify the simultaneous effects of decreased adjacent channel interference at the expense of I channel energy. Finally, probability of error curves vs SNR are presented for BPSK and SBPSK modulations transmitted through a band-limited and hard-limited channel.

This 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.

Aux fréquences de la bande EHF (20-50 GHz), les gaz, les nuages et surtout la pluie provoquent un affaiblissement du signal entre les stations de télécommunication terrestres et les satellites. Les séries temporelles d'affaiblissement présentent des caractéristiques particulières, tel que des périodes de grande variabilité (hétéroscédasticité) et des queues de distributions épaisses. Leur comportement statistique est similaire à certains cours de bourse ou taux de change, ce qui suggère que des modèles de prédiction originellement développés pour des applications financières pourraient être appropriés. L'analyse statistique des séries temporelles d'affaiblissement conduit à un modèle non-linéaire de type ARIMA-GARCH. Ce modèle permet d'obtenir de meilleures performances de prédiction que les modèles existants, notamment grâce à l'estimation de la variance conditionnelle de l'erreur de prédiction.
Afin 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.

Resumo:
The National Research Council of Canada (NRC) and Honeywell Aerospace (EMS Aviation Technologies Inc. Canada) completed prototype testing of its helicopter Satellite Communications (SATCOM, Aspire 200 Series) system for certification assessment. As the NRC Bell 412 is experimental (fly-by-wire control system, upgraded engines and displays), the Honeywell HSD-400i system payload represented a surrogate integration on a standard Bell civil utility transport helicopter. Following NRC's airworthiness clearance, ground testing was completed with data collected encompassing aircraft performance, SATCOM performance, and radio frequency (RF) energy surveys. There was no negative influence of the integration or associated testing on aircraft engine or transmission performance. NRC aircraft radio frequency measurements indicated safe SATCOM RF energy outputs. Externally, higher RF energy output occurred in the aircraft's first quadrant (i.e.; nose and right of nose). Internally, higher RF energy occurred in the aircraft's cockpit decreasing towards the aft-cabin. Honeywell measurements of throughput, bandwidth, and linking via real time data analysis indicated acceptable SATCOM performance. Data rates for SATCOM reception and transmission were analyzed where worst case connectivity was assessed to be 25% less than those for best and baseline case rates. Overall, analyses by Honeywell engineers indicated that acceptable performance is expected for Aspire-200 systems integrated into transport utility class helicopters such as the NRC Bell 412 providing knowledge for Honeywell's substantiation of future SATCOM product Special Type Certificate applications.
