      Research and Design of Onboard Double Antenna Orientation BD2 Receiver

      摘要:
      针对使用北斗二代卫星导航系统实现飞机航向确定的接收机尚无实际应用,提出了一种机载双天线定向接收机;首先介绍了双天线定向原理,从射频前端处理、基带数字信号处理、定位测向解算模块等方面分析了适用于北斗二代信号体制的接收机设计方案,研究了基于LAMBDA算法的载波相位双差定向算法;最后进行实验验证,结果表明接收机平均定向精度可达0.121°/m,可以满足飞机定向应用要求.
      Abstract:
      According to the fact that the receiver which utilize BD2 satellite navigation system to determine the orientation of aircraft have not put into practical application, this paper presented an onboard double antenna orientation receiver.First of all, the principle of double-antenna orientation was introduced.The receiver design scheme which is adapt to BD2 signal system was introduced from RF front-end processing unit, baseband digital signal processing unit and position/orientation determination module three aspects.What's more, carrier phase double differential algorithm based on LAMBDA was researched and designed.Finally, examination was carried out.The result shows that average orientation accuracy of receiver is 0.121°/m, which meets the requirement of aircraft orientation.
