Abstract: Real-time data acquisition is the key to control system.How to effectively improve system data processing,transmission and signal control mode is a major problem to solve.This research set the processing and calculation of high speed acquisition strapdown inertial navigation data an example,gave a detailed introduction of joint work by DSP chips,and adopted dual-port RAM data transmission technology.Data reading adopts the method of FPGA programmable technology,and is capable of data collection,transmission and calculation of laser strapdown inertial navigation system.The research has achieved the navigation data processing for heading,rolling,pitching,speed and position,while the output data update frequencies come up to 500~1000Hz,so as to improve the carrier’s attitude tracking accuracy.

Key words: Navigation system,DSP,Dual-port RAM,FPGA,Laser gyroscope
