Abstract 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 munication mode increases signal
,
transmission distance and flexibility it is convenient to a
