Impact analysis of the extension of the GNSS signal availability (Space Service Volume Extension - SSV) on existing GNSS Precise Orbit Determination (POD) concepts for satellite missions in LEO, MEO, GEO, GTO and HEO.

The study is supposed to provide a wide-spread analysis not only limited to POD concepts, but also investigating the impact of the SSV extension on operational concepts for space users, GNSS software design, and ground operations. The study shall identify drivers for potential new POD concepts, for new operational concepts, for potential changes of on-board technology and ground segment operations.The study logic will be :1- Analysis of the impact of the GNSS SSV extension on- existing POD concepts- existing POD software- existing operational concepts- ground operation2- Identification of drivers for- potential changes of the on-board technology- potential new POD concepts- potential new operational concepts- communication demands between ground and space segment- potential changes of ground segment operations
