Multipaths are one of the major sources of errors for satellite navigation systems. The goal of this article is to present some advances on propagation channel modelling for GNSS mobile users and to show how GNSS receiving algorithms are sensitive to the modelling of the channel. Two channel characteristics are analysed in the paper: the resolution of the environment level of detail, and the resolution of the channel, meaning the number of significant echoes in the tapped-delay line. Particular focus is made on mitigation techniques using antenna arrays to reject multipath. The influence of the channel model will be then interpreted considering three different types of GNSS receiver algorithms, namely conventional DLL/PLL, beam forming and SAGE/STAP algorithm.

This paper describes a wave propagator that can be used to simulate radio occultation measurements. The wave propagator is used to simulate a number of radio occultations based on European Centre for Medium-range Weather Forecasts ECMWF atmospheric profiles. The output from the wave propagator is used as input to a Full Spectrum Inversion FSI retrieval module, which calculates geophysical parameters. These parameters are compared to the ECMWF atmospheric profiles. We also compare the output from the wave propagator with that of a 3D ray tracer. Such comparisons can be used to reveal system errors and get a better understanding of the physics of the problem and the retrieval errors in the inversion of radio occultation measurements.

Reconfigurable on-board antenna systems are a potential solution to mitigate the effect of atmospheric fades in broadband SatCom. The on-board power is dynamically shared among the users according to the time and space-varying meteorological conditions in the service area by tuning the antenna radiation pattern. An efficient algorithm of dynamic on-board power allocation is presented here. Preliminary results show the superiority of the adaptive technique over a state-of-the-art fixed antenna system in terms of on-board power reduction to achieve a given service availability target.

Propagation effects such as rain or clouds attenuation cause deeper fades in the Ka-band than at lower frequencies. In this collaborative paper, the main results of four long-term Ka-band propagation campaigns are presented. The experiments are carried out in Ottawa, Canada; Aveiro, Portugal; Madrid, Spain; and Toulouse, France. Attenuation statistics are derived from satellite beacon data collected over 6 years at Aveiro, 5 years at Ottawa and Madrid and 2 years at Toulouse. Multi-year measurements allow the production of more stable statistics reflecting the long-term behavior of propagation phenomena and to investigate its year-to-year variability. The beacon signal data was monitored and collected on a continuous basis over the whole measurement period. After a brief introduction of the experiments, rain rate and excess attenuation results are discussed, first for a common measurement period and later for the whole database available. Seasonal attenuation statistics for Ottawa and Aveiro are compared. Finally, fade duration and fade slope statistics derived at three locations are presented and discussed.

The main objective of the ESA ARTES 5.1 Contract 20887/07/NL/LvH “Verification of Propagation Impairment Mitigation Techniques” with Politecnico di Milano as Prime, ONERA and Space Engineering as subcontractors, was to validate the channel models and related input data appropriate for the design, analysis and/or control phase of Propagation Impairments Mitigation Techniques PIMTs, both for the Broadcasting Satellite Service BSS and the Interactive Multimedia Broadband Service IMMBS. For the BSS scenario, which is the focus of this paper, the On Board Antenna Pattern Reconfiguration OBAPR PIMT is investigated, using as channel models the rain field generators able to provide the spatial distribution of rain across the service area on the basis of large-scale meteorological forecasts. Their performance were tested using either radar data or a large dataset of beacon measurements collected in Europe during the OLYMPUS experiment.

This paper addresses the integration of a Fade Mitigation Technique FMT within a centrally managed MF-TDMA satellite network in the context of guaranteed QoS delivery. Burst Length Control BLC is introduced as a suitable FMT and the methodology of its design and implementation within the existing DVB-RCS standard is described and simulated. The proposed technique provides compensation for rain attenuation at the expense of capacity utilisation. Within any fixed partition of the MF-TDMA space, by considering the space-time properties of rain attenuation, suitable geographical multiplexing of rain-attenuated and non-attenuated links allows the optimisation of the channel capacity utilisation while still exploiting the statistical multiplexing of the sources on the return channels.

Despite that theoretical, design and experimental studies connected with the creation of large deployable antenna reflectors have already been carried out for quite a long time, this area still remains of lively interest and has good application prospects. An example is the program of the European Space Agency ESA on the creation of a qualified variant of a 15 m deployable space offset reflector. It should be said that by the time the ESA adopted a decision on the implementation of this program, a deployable space reflector 7 m in diameter had already been created in Georgia and, in 1999, this space reflector was successfully tested aboard the orbital station “Mir” according to the joint Georgian--Russian program.Georgian Institute for Space Constructions, continues developing new design principles for large space deployable systems Transformable Space and Ground Structures in Russian, A Monograph, Georgia--Germany--Liechtenstein, 1995.In the paper we describe the invention of an absolutely new design of a space antenna for symmetric and nonsymmetric radio telescopes, which has been developed by the team of Georgian designers headed by Professor E. Medzmariashvili.The novelty consists in that new engineering and technological effects we obtained by synthesis of ring-shaped and rib-umbrella type systems.In particular, the central hinge that connects the main levers of the pantograph is arranged asymmetrically. As a result of this asymmetrical arrangement, during deployment the consoles folded along the package longitudinal axis and connecting the adjacent sections move in radial directions from the center to the periphery and, simultaneously, deploy in an umbrella-like manner.

Channel state estimation is one of the key processes carried out at the physical layer of Satellite Systems employing Fade Mitigation Techniques such as Adaptive Coding and Modulation ACM. An accurate and reliable channel estimate is needed to fully realize the capacity gains accrued by using ACM. In this paper the SNR estimation algorithms, which perform the role of channel state estimators, are analysed from a system point of view to get a quantitative idea on the number of received symbols needed to get a reliable estimate, and the impact of interference noise on it. A DVB type satellite system has been investigated for the study. An improvement over the Maximum Likelihood ML estimator using Bayesian principles is suggested and illustrated.

Project objectives: The core of ANASTASIA (Airborne New Advanced Satellite Techniques & Technologies in a System Integrated Approach) research is to provide on-board Communication, Navigation and Surveillance (CNS) solutions to cope with the foreseen doubling of air traffic by 2020. ANASTASIA will carry out research of future technology and system architectures for navigation, resulting in the development of a new generation of airborne Global Navigation Satellite System (GNSS) receivers for all phases of flight. Such systems will offer accurate and safe global navigation while reducing avionics cost through the optimisation of the number and complexity of on board equipment. On the communication side, work will concentrate on the design and implementation of a prototype Satcom system that will meet the evolving European Air Traffic Management (ATM) requirements. Research will also be made into higher bandwidth services, systems and airborne equipment to efficiently meet long term future aircraft communication requirements, including both ATM and passenger needs. The future needs of Surveillance will be consolidated with the requirements and key technology tests from Communications and Navigation. Expected results: The main goal of ANASTASIA is to pave the way for the introduction of new satellite-based technologies into aircraft operations in both Navigation and Communications. The main outcome of ANASTASIA will be recommendations for future civil aircraft operation and a set of evaluated technologies and avionics architectures achievable from 2010 that will enable more autonomous, satellite-based aircraft operation. Paper focus: After a general description of the rationale of the project and of its global CNS objectives, the focus is made in this paper on the communication side where more detailed objectives and initial results are presented.
