Personal Satellite Services

Future Personal Satellite Services (PSATS) represent a trendy research area due to its importance that it may have in the our daily lives. Being the personal services related to users, they deal with services and devices whose nature is pervasive. All these concepts have been clearly addressed in the Personal Satellite Services 2011 Conference (PSATS’11) through different interesting talks and in this special issue where original contributions selected from the set of papers presented to PSATS’11, have been extended and published after a severe two-round review process. In more detail, among the topics that deal with Personal Satellite Services, this special issue focuses on four topics: i) dual frequency receivers performance for Galileo-based tracking services; ii) integrated radio systems; iii) transport layer protocols; iv) security issues in Delay Tolerant Networks.
