北斗/罗兰-C组合定位技术

Integrated Positioning Technology of Beidou/Loran-C System

摘要:

“北斗一号”是我国的卫星导航系统,其有源定位模式使其很难得到广泛应用。为此,提出了一种北斗/罗兰-C组合定位方案以实现无源定位。该方案利用“北斗一号”两颗卫星和地面罗兰-C台站获得的距离差信息实现双曲线相交定位。仿真结果表明,该方案的精度可以满足一般定位要求,具有较强的实用性。

Abstract:

“Beidou-1(BD-1)” is a dual star navigation system of China. Because of its active positioning mode, the application of the system has many restrictions. In order to solve the problem, a new integrated positioning method based on BD/Loran-C system was presented. The proposed method uses the range difference information obtained by BD-1 and Loran-C to achieve hyperbolic intersecting positioning. Simulation results indicated that the precision of the proposed method could satisfy general positioning requirements and be of strong practicability.
