The electronic system of polarization grating navigation sensor utilizes a new architecture of hardwaresoftware which adapts to real-time image processing of all-sky polarization information

which has higher resolution and precision. In order to verify feasibility of this new architecture

and provide platform

for research on algorithm for navigation information extraction from image

a design scheme for electronic system of sensor is proposed

on the basis of interpretating its principle for polarized light navigation. The electronic system is a system on a programmable chip（SOPC） based on FPGA

which acquires preceeding stage polarized detecting image datas through Cameralink protocol

through hardware algorithm modules and Nios II CPU to calculate course bearing and send to upper computer through serial communication. The test indicates that the electronic system is able to achieve the task of polarized image acquisition and processing

and update rate and calculating precision of output datas is up to 20 Hz and prior to ± 0. 01° respectively

and it is convenient for algorithm verifying navigation information extraction from image in hardware circuit.
