7D State Parameter Measurement for Flying Aircrafts with DGPS

    摘要
  • 摘要: 针对GPS卫星SA和AS技术的人为精度降低措施,应用多个地面基准站的DGPS载波相位测量模式,精确地测得了飞机在航三维实时点位、对地摄影时元和三维飞行速度;其二维点位的外部符合精度达到了±7.9cm,高程外部符合精度为±18.1cm。

     

    Abstract: GPS kinematic carrier phase measurements can be used to determine seven dimensional state and three attitude parameters of a motional carrier such as an aircraft and low earth orbit spacecraft,on which an antenna is installed to receive GPS signals.It is known from airborne GPS test results for photogrammetry in China since 1994 that GPS carrier phase measurements in a motional environment have acquired external accuracies of ±7.9cm for two dimensional positions and ±18.1 cm for point heights.
