    • Method and apparatus for determining locations of static devices are disclosed. The method includes identifying a plurality of static devices, obtaining location measurements by the plurality of static devices at different times, and determining locations of the plurality of static devices using the location measurements obtained at the different times. The method of determining locations of the plurality of static devices includes determining a group location of the plurality of static devices based on GNSS pseudo range measurements contributed by the one or more static devices, where the group location is near a centroid of the plurality of static devices weighted by the number of GNSS pseudo range measurements contributed by each of the plurality of static devices. The method of determining locations of the plurality of static devices further includes sharing a common time reference among the plurality of static devices.
    • 公开了用于确定静态装置的位置的方法和装置。 该方法包括识别多个静态设备,在不同时间通过多个静态设备获得位置测量,以及使用在不同时间获得的位置测量来确定多个静态设备的位置。 确定多个静态设备的位置的方法包括基于由一个或多个静态设备贡献的GNSS伪距测量来确定多个静态设备的组位置,其中组位置接近多个静态设备的质心 由所述多个静态设备中的每一个所贡献的GNSS伪距测量的数量加权的设备。 确定多个静态设备的位置的方法还包括在多个静态设备之间共享公共时间基准。
