摘　　要：论述了目前罗兰C和卫星导航组合应用的几种方式,对罗兰C和卫星导航伪距组合定位以及罗兰C和卫星导航定位数据融合的原理和方法进行了论证,通过罗兰C和卫星导航的组合应用,可以克服单一导航系统的弱点,提高组合导航的性能,拓展了罗兰C的应用领域,延长了罗兰C的使用周期。Several mode of Loran-C and satellite navigation combinatorial application are described. The principle and method to how to use Loran C and satellite navigation pseudo range to get position data and how to use Loran-C position data and satellite navigation position data to get a fused position data are illustrated. The combinatorial application of Loran-C and satellite navigation can overcome the drawback of single navigation system,enhance the performance of combinatorial navigation system, expanded the application domain of Loran-C and extended the life cycle of Loran-C.
