Due to site constraints within worldwide for the Beidou global navigation satellite system(BGNSS),the global navigation integrated information(GNII)must be transmitted through the inter-satellite links(ISL).One of its core problems is to meet the path selection of GNII transmission in BGNSS,the research method of this problem is provided in paper.The link characteristics is analyzed to explore the constraint factors and constraints relation on path selection when GNII is transmitted.And then the constraint factors and constraints relation of path selection is studied under analyzing the BGNII.Finally the feedback adjustment mechanism about constraint factors to adapt the ISL characteristics and transmission requirements is explored through the modeling analysis of the constraint factors and its relationship,and the adaptive path selection strategy and mechanism of GNII transmission based on ISL is validated with simulation.
