As the kernel component of GPS receiver, the direct development of the GPS OEM board has some advantages in application, such as feasibility, convenience, economy and modulization, etc. In the paper, the detailed development as well as some related items of the GPS OEM board are discussed, and the timing performance and the lpps output are also researched with the Motorola M12MT＋ TIMING ONCORE as an example. As a result, the method of accurate timing using GPS OEM board is presented, and an accuracy analysis is provided, which is helpful for the accurate timing in surveying.
