| 摘 要： | 现有局域机场监视系统（LAM）采用单接收机，健壮性和完好性较差.基于多接收机LAM（MLAM）概念，从地面监测站和机载用户两方面讨论了其完好性.在地面监测站方面，研究了多接收机伪距校正数校验方法；通过地面监测保护级最小原则选择最佳可见卫星组合，减小了机载用户的计算负担.在机载用户方面，考虑系统完好性、连续性和可用性的前提下进行漏检系数计算，精确估计了机载用户保护级，改善了系统的整体性能.实验结果表明，与LAM相比，MLAM的精度和完好性指标都得到了提高.

| Abstract: | The existing local airport monitor(LAM) with single receiver is not robust,and its integrity is not good enough.Based on multi-receivers local airport monitor(MLAM) concept,its integrity was discussed on both ground monitor station and airborne user.For ground monitor station,the multi-receivers pseudorange corrections verifying method was studied.Through using least monitor protection level principle to choose the optimal visible satellites combination,the computation complex is reduced.As to the airborne ... |
