Abstract： （1）the overall design space to improve the precision of the signal Compatible in the greatest degree based on the Beidou satellite navigation system， from the aspects of space to improve the precision of system signal broadcast， analysis， demonstrate the feasibility and performance index distribution service system are given a clear spatial signal precision enhancement system interface design， to complete the space signal accuracy to improve the overall design， guide topic 2 （key technology the accuracy of signal space the engineering realization of lifting）. （2）the overall design foundation navigation signal network Study on the ground navigation signal influence factors， service precision positioning accuracy of 5 meters of the index distribution， design and demonstration foundation navigation signal network signal system， finished the foundation network pseudo satellite navigation signal layout scheme and time synchronization scheme research. Guide the project 3 （key technology of Beidou ground navigation signal network） project implementation. （3）system integration and test Complete the accuracy of signal space lifting system integration design， space signal lifting test scheme design， foundation navigation signal network station layout scheme design， foundation strength demonstration system integration design， foundation navigation signal network test scheme design； spatial signal lifting system integration， network integration， to build the foundation of navigation signal the Beidou service performance test system； organize UERE better than 1 meters， the positioning accuracy is better than the technical index test 5 meters， forming a demonstration test report. （4）the PNT architecture and Application Research Based on Beidou This research mainly based on the PNT system requirement analysis， the application of PNT system model and key technology research， research on the standard system of PNT. Eventually formed a "research framework and application of PNT report system based on beidou".
