Abstract:	This study is performed to determine whether Global Navigation Satellite System (GNSS) signals can be utilized in outer space. More specifically, the GNSS satellite visibility and geometric dilution of precision (GDOP) in outer space are performed in this study by utilizing a satellite location positioned at the nadir direction using the ephemeris data of the GNSS satellite. This study also discusses whether the number of visible satellites meets the minimum number of satellites, which is four, to conduct point positioning through the multi-GNSS, multi-frequency, and 1st sidelobe utilization scenario. In the GDOP analysis phase, the expected navigation performance error is calculated, and the environmental characteristics of GNSS signals that are revealed according to an altitude are analyzed by utilizing a skyplot. Finally, the applicability of GNSS signals in the space mission is investigated based on the above results.
