The overall research on BeiDou augmentation system in China transportation

Transportation is the largest application field of satellite navigation at present, which has the characteristics of “large scale, multi-mode, wide range, high demand” and so on. Currently, Ministry of Transport of the People´s Republic of China is promoting the construction of “Four Traffic (Comprehensive Traffic, Intelligent Traffic, Green Traffic and Safe Traffic)” and higher demand for the precision, continuity and reliability of satellite navigation service is proposed. The construction of satellite navigation augmentation system has become the objective demand for the in-depth application of satellite navigation in transportation. Satellite navigation augmentation system can be divided into temporary augmentation system and permanent augmentation system based on the analysis in this paper. Permanent augmentation system includes dedicated system, professional public service system, general public service system and commercial service system. Permanent augmentation system has experienced the preliminary development stage and the independent development stage oriented to various professional applications. At present, permanent augmentation system has entered the stage of resource sharing and integration development which has the main characteristics of basic integration, products segmentation, diversity service and application popularization. The construction of China satellite navigation augmentation system is under the second development stage and the augmentation system should be constructed according to the characteristics of the third stage. The construction of China Beidou ground-based augmentation system was started in the middle of 2014 which will have the effect of basic fusion. Based on this, Ministry of Transport of the People´s Republic of China is discussing the construction of China transportation BeiDou augmentation application system. This paper analyzed the inland, coast, road transport, road infrastructure and public transport demand for high precision navigation position service, and then proposed the general concept of the construction of China transportation on satellite navigation augmentation system and experimental verification is carried out focus on transportation satellite navigation augmentation service application.
