    • A system and method for automated differential correction processing of field data in a global positioning system (GPS). In one embodiment, the present invention retrieves GPS field data collected by one or more GPS receivers from a storage device, and then automatically selects the most appropriate differential correction scheme to generate a solution without user intervention. More specifically, the present invention executes a code-based correction scheme to generate a code-based solution for the field data. Next, the present invention examines the field data to determine whether a carrier phase correction is applicable. If the field data supports carrier phase correction, the present invention generates a carrier phase solution, compares it with the code-based solution, and returns the more accurate of the two solutions as the final result. If the field data does not support a carrier phase correction, the present invention returns the code-based solution as the final result. Thus, the present invention provides a system and method for post-processing of GPS field data which does not require a user to know and understand the contents of the field data, to deal with multiple user interfaces, or to read and interpret different results generated by various processing schemes. In other words, the present invention provides a single software package for post-processing of GPS field data without extensive user involvement. As such, the present invention greatly reduces the complexity of GPS field data post-processing and enhances the usability of GPS equipment.
    • 一种用于全球定位系统(GPS)中现场数据的自动差分校正处理的系统和方法。 在一个实施例中,本发明从存储设备中检索由一个或多个GPS接收器收集的GPS场数据,然后自动选择最合适的差分校正方案以产生无需用户干预的解决方案。 更具体地,本发明执行基于代码的校正方案以产生用于场数据的基于代码的解决方案。 接下来,本发明检查现场数据以确定载波相位校正是否适用。 如果现场数据支持载波相位校正,则本发明生成载波相位解决方案,将其与基于代码的解决方案进行比较,并且作为最终结果返回两种解决方案的准确性。 如果现场数据不支持载波相位校正,则本发明作为最终结果返回基于代码的解决方案。 因此,本发明提供了一种用于后处理GPS场数据的系统和方法,其不需要用户知道和理解现场数据的内容,处理多个用户界面,或者读取和解释产生的不同结果 通过各种处理方案。 换句话说,本发明提供了用于后期处理GPS场数据的单一软件包,而无需广泛的用户参与。 因此,本发明大大降低了GPS场数据后处理的复杂度,提高了GPS设备的可用性。
