导航通信融合定义、方式与典型系统

随着人们对定位安全和定位准确性要求的提升,仅仅依赖卫星导航系统已经不能满足用户在各种复杂环境下的个性化定位需求,在此背景下,通信导航一体化技术应运而生。移动通信网络具有覆盖广、用户数量大和安全保密性好等优点,将通信系统作为卫星导航系统的有效补充,可以有效提升导航系统的性能。导航通信融合技术已经成为导航领域未来发展的重要技术热点,但目前缺乏清晰的导通融合架构和导通融合方式。从导通融合的技术层面进行划分,提出了波形融合、信息融合、硬件融合三种导通融合方式,分析了通信系统的辅助信息对导航系统精度和抗干扰能力的影响,以及两种典型的导通融合系统的优缺点,并对其未来的发展进行了展望,补充了导航通信融合技术的基础理论,对导通融合技术的发展具有重大意义。

Definition,Method and Typical System of Navigation and Communication Fusion

As people's requirements for positioning safety and positioning accuracy increase,single satellite navigation can no longer meet the user's personalized positioning requirements under various complex conditions.In this context,communication and navigation fusion technology has emerged.The communication network has the advantages of wide coverage,large number of users and good security and confidentiality.Using the communication system as an effective supplement to the satellite navigation system can effectively improve the performance of the navigation system.Navigation and communication fusion technology has become an important technical hotspot in the development of navigation field,but currently a clear conduction fusion architecture and conduction fusion methods are still lacking.This paper divides the technical levels of navigation and communication fusion,and proposes three navigation and communication fusion methods:waveform fusion,information fusion,and hardware fusion.The influence of the auxiliary information of the communication system on the accuracy and anti-interference ability of the navigation system is analyzed,and two typical fusion systems,with the advantages and disadvantages of the systems are analyzed.The future development is prospected.This paper is a supplement to the basic theory of navigation and communication fusion technology,which is of great significance to the development of conduction fusion technology.
