Research on ADS-B ‘In’ Strategic Development

ADS-B is an important technology in next generation ATM, it's included two parts ADS-B `In' and ADSB `Out'. Because ADS-B `In' has benefits to enhance ATM operation safety, increase airspace capacity and efficiency, so it's already been a new technology to support next generation ATM using by China, Europe, and the United States. However, comparing with ADS-B `Out' which has already been implemented, the research achievements of ADS-B `In' is still less, many aspects of ADS-B `In' should be researched urgently. Firstly, this study researches ADS-B `In' development roadmap of Europe and United States, and combines with ADS-B `Out' mandatory policy of Europe and the United States, finding out the two key factors of ADS-B `Out' mandatory performance requirements are closely related to ADS-B `In' development. It has important significance for the long-term planning of ADS-B `Out' performance requirement of China. Secondly, extracted the application requirements of ADS-B `In' based on ATM development strategy of China, so that recommended four types of ADS-B `In' application are needed. It recommends the two new technologies cooperation solutions for combine ADS-B `In' with other new technologies to get the maximum benefit. Finally, a large-scale demonstration method of ADS-B `In' application are proposed in this paper and realized the quantitative analysis of ADS-B `In' application benefit evaluations. The research results of this study are great significant to research and development of ADS-B `In' of China.
