Abstract


Based on the needs of the modern fire control positioning systems and development , we propose a regional positioning system is designed to meet the disruption in the GPS positioning system can still be the case for the artillery to provide positioning information requirements. This paper first analyzes the regional positioning system components , positioning theory and signal structure, in theory, to verify the feasibility of regional positioning system . Then focuses on the regional positioning system receiver hardware configuration and circuit design . The receiver hardware design using Zarlink GP2015 produced as a receiver RF front-end chip , the realization of the signal downconversion ; GP2021 chip as the C / A code baseband correlator for IF digital signal demodulation and despreading , get navigation Message : LPC2214 microcontroller as a receiver , to complete the associated channel data read, operation and control of the state of loop . This typical receiver design , not only can receive regional positioning system measurement signals can be the GPS satellite signal reception , in order to verify the feasibility of the hardware design . This paper also underlying software for the receiver modular design not only reduces the coupling between the various software modules , but also to facilitate and expand the functions of the system and software maintenance . The author is responsible for the project in the receiver's hardware design , mainly to complete schematics and PCB design, circuit board debugging work and preparation of test procedures for testing the receiver . Test results validate the receiver can work, meet the design requirements .
