Abstract:	This paper presents test results of the performance assessment of the predicted UWM-IPM model in mediumrange RTK positioning. The rover data collected within 25 to 67 km from the closest reference station were processed in kinematic mode with the support of the ionospheric corrections derived from the UWM-IPM model. The RTK solution was derived in single- and multi-baseline modes. All numerical tests were carried out using the MPGPS software developed in cooperation with The Ohio State University. The recent extension to the software developed at the University of Warmia and Mazury (UWM) allows for using the predicted ionosphere information. The test results are very promising, and indicate that the predicted ionosphere model can effectively support medium range RTK positioning, and allows for fast ambiguity resolution over distances of several tens of kilometers under moderate ionospheric conditions..
