Based on an analysis of the connotation of smart tourism and the perspective of smart scenic construction, a concept of BeiDou Satellite Navigation System (BDS) smart tourism is proposed. Later on, some related key issues are discussed such as system architecture, wide-area continuous coverage positioning network technology, and wide-area continuous coverage communication network technology. Taking Jiuzhai Valley as experimental construction spot, the BDS smart scenic location-based service (LBS) system was developed and deployed. With such technical features such as both way, teamwork, information push, and remote interaction, this system improves the tourist LBS, fine management, and unexpected event handling capacity of the resort. Finally, the paper recommends the BDS smart tourism LBS system to become an important part of the one belt and one road (OBOR) strategy, for it is believed that this system will significantly speeds up the intelligent tourism construction of the neighboring countries, promote the cultural exchange and cooperation, and drives up the economic development of the concerned regions.
