摘要
多星座导航系统的组合共用是近年来卫星导航领域的发展方向之一。综述了基于组合导航卫星系统定位技术的最新研究进展,从多源信息融合理论的角度阐述了卫星导航系统组合定位的思路,同时在多星座导航系统组合的新背景下分析了载波相位模糊度解算这一关键问题的发展,探讨了系统组合共用实施中有待于进一步研究解决的新问题。
The integration and application of multiple Global Navigation Satellite Systems （GNSS） is gradually becoming a trend in the field of satellite navigation in recent years. The progress of the positioning techniques based on integrated GNSS is reviewed. The clue of the positioning method is illustra- ted from the viewpoint of the multi--source information fusion theories. The progress of the crucial techniques such as the carrier phase ambiguity resolution methods are analyzed for the new background of the integrated GNSS. The newly emerging issues and problems to he further studied in the implementation of the integrated GNSS are also put forward.
