摘　　要：卫星导航系统应用广泛,有利于促进国民经济的快速发展。本文在介绍国内卫星导航系统及其国内市场状况基础上,结合北斗卫星导航相关产业发展趋势,从组合导航、增强系统、时钟同步和定向解算等方面分析了北斗卫星导航系统的技术成果,并讨论了有助于提高北斗卫星导航系统精度的相关辅助技术的发展情况。最后结合我国国情和国内卫星导航系统相关技术特点,给出我国第二代卫星导航定位系统发展的若干建议。Satellite navigation systems are used extensively, and are profitable for advancing the national economy. Beidou satellite navigation system and its domestic market are introduced in this paper. Combined with the developments and trends of Beidou satellite navigation system, some techniques of Beidou satellite navigation system are discussed, such as integrated navigation, enhanced system, clock synchronizing and orientation resolving. Then, the developments of some relational assistant techniques to advance Beidou satellite navigation system precision are discussed. According to the situation of our country and the characteristics of domestic navigation system, suggestions are put forward to accelerate the research of domestic second generation satellite navigation system.
