There are several new systems emerging in the Global Navigation Satellite Systems era. The US GPS system is under modernization, the European GALILEO has established ramp-up plans, the Russian GLONASS is going to be restored, and China has its own plans on the global Beidou/Compass navigation system. In addition, there are national satellite systems planned, e.g., in Japan and India, and the established continental geostationary WAAS and EGNOS augmentation systems. These all set new challenges to positioning receiver design, as multiple frequencies, modulations, message protocols, and system parameters have to be coped with. This tutorial gives an overview of the challenges and solutions in the receiver chain: antennas, RF front-end, receiver baseband algorithms, baseband hardware implementation, PVT (position, velocity, time) solution computation software, and also hybridization with sensors producing other than satellite-based location or kinetic information.



Service Modeling with SoaML

SoaML (Service oriented Architecture Modeling Language) is a new OMG standard for Service Modeling adopted in December 2009, with both a UML profile and a metamodel for modelling of services. This tutorial introduces the concepts and practical use of SoaML with corresponding tool and methodology support. The tutorial is provided in two parts. Part I provides an introduction to SoaML for Service Modeling and Service oriented architectures and Part II shows how SoaML can be used and extended in a wider context including a link to business modelling with BPMN 2.0, modelling of service variability, and support for semantic web services and agent modelling. It is also shown how SoaML can form a foundation for future enhancements, like support for P2P/Grid/Cloud etc. that can be build upon the SoaML metamodel and UML profile. The SoaML standard has been developed with support from the European FP7 SHAPE project and members of the SoaML standardisation team and the SHAPE project will present the tutorial. The tutorial will be using running examples, and the participants will get access to a SoaML toolkit for their own computer to use as part of the tutorial.
