According to the desert ants Cataglyphis navigation mechanism

subsection navigation algorithm is used to research the polarized light navigation sensor using MSP430 as control core.The sensor uses two voltage signals of variation to calculate navigation angle through subsection algorithm

it has high resolution

the mixed signal processor is used to reduce power consumption of the sensor

wireless communication mode increases signal transmission distance and flexibility

it is convenient to apply.The sensor navigation mechanism and subsection navigation algorithm are analyzed.The sensor hardware circuit and software program are designed

and the sensor prototype is made.In order to test the performance of the sensor

experiments are carried out on the calibrating platform

the original error of the sensor is within 0.6°

after compensation

navigation precison is within 0.2°.The experiment verifies that the polarized light sensor navigates independently

it has high precision and works stably and has broad application prospect in navigation system.
