Based Vrs Network Decimeter Differential Gps Receiver Design,

The thesis primarily sets forth the design of the decimeter DGPS receiver based on VRS NET.The system design is set forth from the under many aspects,firstly discusses significance and status quo of domestic and overseas about the subject, simply introduces GPS positioning principle and difference technology; secondly sets forth common RTK technology limitations and emphasis discusses mature VRS technology superiority;lastly completely discusses design of system hardware and software and integrated circuit devisal.In a word,the system improves DGPS receiver positioning standard based on VRS NET.and selects positioning standard well GPS-OEM board,appliance GPRS internets wireless NET,and accomplishes data transmission, realizes GPS receiver difference positioning.The system is satisfied decimeter positioning standard design demand through many experiments.
