With the development of IT,positioning and directional devices are used more widely on the troop sharply motorment and become the necessary tools to deal with emergency.With the high sensitivity sensors,we can bring out rapidly positioning and precisely directiontng device to provide safeguard for the troop moving.This paper discussed the design and implement of portable positioning and directional device using interrupt techniques and compensation with declination based on PC-104 module.The geographical informat ion is read from the GPS,then the declination is computed using the longitude and latitude,last,the dictional information from the digital compass pluses the declination,the dictional data is obtained.So the purpose of rapid positioning and pricise directional is reached.
