Application and design of miniature solid state heading measuring system

With the rapid development of science, heading measuring system is becoming increasingly pint sized and intelligent. Miniature HPR 1 magnetic heading measuring system is just researched and developed in such background. It consists of HMR3300 digital compass, which is manufactured by Honeywell corporation, employed SCM and external hand held display controller. This system can not only complete the real time collection of such signals as heading, pitch, roll and deviation, but also provide users numeral and analog output after the error compensation. The experimental results show that it is accurate, reliable and flexible in operation. It can be used not only in unmanned aerial vehicles (UAV), but also in other fields such as cars and ships.
