✦ Synopsis
In this paper a methodology for the characterization of environment-related (shadowing and multipath) propagation effects on multi-satellite systems is presented. This work is focused on availability and performance evaluation of global navigation satellite systems (GNSSs). The definition of next-generation GNSSs specially designed for civil applications requires the precise understanding of propagation effects; these include not only ionospheric and tropospheric but also environmental effects, since a large group of their expected users will no longer be located in open areas with clear visibility of several satellites but in densely built-up areas subject to high blockage probabilities. Issues such as constellation definition, signal design, codeword structure, etc. require the aid of powerful analysis tools. The basic ideas for the specification of such multi-satellite propagation analysis tools are presented.
