The invention discloses a combined navigation unit and an implementing method thereof. The unit comprises an MINS, a geomagnetic compass heading system, a GPS, and a CDMA mobile phone network positioning system. The method comprises that: a navigation computer synchronously receives navigation data of the GPS, dead reckoning data of the MINS, data of the CDMA mobile phone network positioning system and data of the geomagnetic compass heading system from four RS232 serial ports by utilizing a time synchronization module, and performs real-time and adaptive combined navigation according to the carrier-to-noise ratio of GPS signals and the quality of CDMA mobile phone network signals; and finally, the navigation computer displays the final navigation data in real time through a navigation data display module. The combined navigation unit has the advantages of small volume, low power consumption, low cost, complete functions, plenty interfaces, and capacity of completely meeting the requirements on medium and low
