Abstract:	This paper explained the concept of the Space Service Volume (SSV) service used in satellite navigation systems and the characteristics of SSV services considered in existing global navigation systems such as GPS and Galileo. We also analyzed the effectiveness of SSV services based on regional navigation systems utilizing GEO and IGSO satellites. For this, the paper analyzed the minimum received power of SSV services for geostationary users and Lunar mission users based on regional navigation systems utilizing geostationary (GEO) and inclination-orbit (IGSO) satellites. The results confirmed that the SSV serviced is useful for GEO users up to 20 degrees of the off-boresight angles and can also be used for Lunar missions within 15 degrees of the angle.
