| Summary: | 碩士 === 中華技術學院 === 電子工程研究所碩士班 === 95 === This thesis primarily focused on discussing Global Position System(GPS) of the hardware test and implementation, the GPS can accurately provide seven kinds data , like as ：the position 、the velocity、 and time of the three-dimension space location。The .24 GPS satellites provide whole world all-weather position and navigate information. for 24 hours。 In 1995American Air Force Space Command Headquarter declares：the GPS has the integrity operation capability(the Full Operational Capability), when replace the 24 satellites of BLOCK I with BLOCK II/IIA ，and go further replace next 4 BLOCK IIAs with BLOCK IIR satellite。 It is successful to meet the operation of the military requirements 。Due to the fast development of the GPS technique。 It makes increasingly the demand of commercial application, the navigate method have more revolution influence than the tradition.。
The cellular phone system not only to provide a traditional speech service, but also to provide the high data transfer rate, it becomes the widely application , even exceeds the service than the traditional switching circuit of the telephone system 。
The GPS development system included the GPS simulator, GPS receiver, emulation parameter, the coordinates axis and the transformation data etc. In this text introduces the GPS system data format first, then introducing the GPS simulator and the emulation parameter setting immediately， and go on to introduce the coordinates axis and the transformation data ，finally we use the mentioned idea and concept to implement and construct the related hardware system。Using the GPS simulator and the GPS receiver to test the structure of the actual hardware system ，when finish the quiescent test., then evaluate the result data via GPS development system to check the discrepancy, and put the correct data in the future design of the GPS hardware loop test ，also provide a suggestion specification and test mode of GPS simulator.。The future study is to use the cellular phone GSM system as the integration research。
