Due to the development of MEMS, there is an opportunity to build a low-cost integrated
navigation systems, operating independently of horizon visibility. This paper presents the proposal of
an integrated GPS/IMU platform using MEMS technology. In order to verify the performance of
a system built at the University of Warmia and Mazury, an experiment was conducted. In this
experiment a precise Javad GNSS receiver, commercial grade GPS/IMU XW – ADU5660 and
own-built system were used. The experiment was conducted to compare the results obtained from self
built device with the working military integrated navigation unit. During the study all three devices
were mounted inside moving vehicle. The car drove route inside the Kortowo campus, during which,
all equipment performed measurements. Then, the results from both integrated systems were
compared with RTK (Real Time Kinematic) results from Javad receiver. Experiments prove that the
performance of own device is comparable to the commercial device
