摘要
目的构建一种新型的北斗/罗兰C组合导航系统,解决北斗系统有源定位的问题。方法利用罗兰C系统对北斗系统进行增强,建立定位数学模型。结果系统定位的仿真结果表明北斗/罗兰C组合系统能够采用无源定位方式,并且定位精度满足应用的要求。结论通过算法的设计为北斗与罗兰C系统提供了一种理想的组合方法,也对同类系统的设计有借鉴作用。
Aim To establish a kind of new Geostar/Loran-C integrated navigation system, which resolves the problem of active location in Geostar system. Methods Strengthen Geostar system using Loran-C system, the mathematics model of the location algorithm about integrated system is established, the equation is offered. Results The simulation result shows that the Geostar/Loran-C integrated system can be in position with passive way, and systematic positional accuracy can satisfy the requirement of application. Conclusion A kind of ideal integrated method has been put forward through the design of algorithm for the Geostar/Loran-C integrated system, also it has reference for the design of similar system.
