    • A positioning system or synthetic phase processor or rover station for providing high integrity positions with graduated accuracies. The positioning system includes one or more real time kinematic (RTK) reference stations for receiving GPS signals at established reference positions and measuring reference phases. The positioning system or the rover station selects a synthetic offset vector and uses the synthetic offset vector for inferring synthetic reference phases to a synthetic position. The rover station uses the synthetic reference phases with actual or virtual reference positions for determining a rover position having an added positional error controlled by the synthetic offset vector. For another embodiment a secure rover station dithers a secure position with a synthetic offset vector for providing an unsecure rover position having the added positional error.
    • 定位系统或合成相位处理器或流动站,用于提供具有分级精度的高完整性位置。 定位系统包括一个或多个实时运动学(RTK)参考站,用于在已建立的参考位置处接收GPS信号并测量参考相位。 定位系统或流动站选择合成偏移矢量,并使用合成偏移矢量推断合成基准相到合成位置。 流动站使用具有实际或虚拟参考位置的合成参考相位来确定具有由合成偏移矢量控制的附加位置误差的流动站位置。 对于另一个实施例,安全漫游站用合成偏移矢量来抖动安全位置,以提供具有增加的位置误差的不安全的流动站位置。
