The Design of Ballistic Measure System Based on the GPS Fixed on shell
HE Guang-lin (Dept. of Electromechanical Engineering, Beijing University of Science & Technology, Beijing 100081, China)
The characteristic and requirements of GPS used in ballistic measure was analyzed, the measure systems of receiver and transmitter and orientated modes of the GPS fixed on shell were discussed. The measure system of GPS fixed on shell was designed with difference numeration project, the emanant mode of transmitter of GPS fixed on shell was selected. The shell part of the system consists of GPS OEM, GPS-based controller, MODEN, receiver and transmitter, RAM and serial interface. The functions of ground workstation are that receives signals transmitted by GPS fixed on shell, computes and displayes the position and speed of shell, and sends control command to shell. The software for shell includes initialization module of OEM board, data processing module and data coding module. The software for ground workstation make up of data acquisition module, computing time module, difference computing module and module for flight track.
