The precise point positioning (PPP) is widely used as a typical representative of GNSS. But the main challenge of dual-frequency PPP is that it requires quite a long time to succeed in the ambiguity-fixed so it takes more than 30 min to obtain centimeter-level accuracy. A combination of GPS and low earth orbit (LEO) satellites can improve the diversity of(More)
Cooperative positioning is a new paradigm in Global Navigation Satellite System (GNSS) positioning. By sharing information with other users and measuring geometrical range between them, the localizability and positioning precision of users can be improved. In this paper, we put forward a two user cooperative positioning model and a positioning algorithm.(More)
