概括定位是移动计算必不可少的服务，虽然典型的 GPS 接收器应用范围很广，但它消耗大量能量，不能用于许多应用。 OB - 在很多传感场景中，位置信息可以在数据上传到服务器时进行后处理，我们设计了云卸载gps（co-gps）解决方案，让传感设备主动执行任务——循环通过 gps 接收器并记录足够的原始 gps 信号以进行后处理。在全球导航卫星系统 (GNSS) 卫星星历和地球高程数据库等公开信息中，云服务可以在原始数据的毫秒级内获得高质量的 GPS 位置。使用我们设计的称为 CLEO 的移动传感设备平台，我们评估了解决方案的准确性和效率。与独立 GPS 接收器上 30 多秒的繁重信号处理相比，我们可以实现低三个数量级的能量位置标记。

(generalization
Positioning is an essential service for mobile computing. Although the typical GPS receiver has a wide range of applications, it consumes a lot of energy and can not be used in many applications. Ob - in many sensing scenarios, the location information can be post processed when the data is uploaded to the server. We designed a cloud unloading GPS (co GPS) solution to let the sensing equipment actively perform the task - cycle through the GPS receiver and record enough original GPS signals for post-processing. In public information such as global navigation satellite system (GNSS) satellite ephemeris and earth elevation database, cloud service can obtain high-quality GPS position in milliseconds of original data. Using our mobile sensing device platform called Cleo, we evaluated the accuracy and efficiency of the solution. Compared with the heavy signal processing of more than 30 seconds on an independent GPS receiver, we can achieve three orders of magnitude lower energy position marking.
