Design results of the M&S software are presented for performance evaluation of integrated terrestrial radio navigation systems. The presented M&S software consists of a navigation environment generation part, a navigation algorithm part and a GUI part. The navigation environment generation part contains a reference trajectory generation module, a measurement generation module and a clock error generation module. The navigation algorithm part contains algorithm modules of navigation systems, integrated navigation modules and a clock synchronization module. The GUI part contains navigation environment configuration module, navigation algorithm configuration module and navigation result display module. The designed M&S software was verified by checking function of each part. Raw measurements are well generated according to the parameter setting of the navigation environment configuration in the GUI. Navigation algorithm results are well transferred to the GUI and the results are well displayed in the GUI.
