Summary:High demands on mobile user positioning cannot be satisfied by single navigation system. The paper proposes multi system solution which utilizes navigation and communication systems and signals. The experimental software receiver is described as development tool of such combined system. The proposed receiver consist of three GNSS RF front ends of bandwidth of 24 MHz tunable to any navigation frequency from 1 to 2 GHz and one DVB-T(H) tuner. The programmable receiver hardware is based on FPGA and PC workstation which communicate each other via Gigabit Ethernet. In the second part of this paper we are presenting methods of estimation of time of arrival of OFDM (Orthogonal Frequency Division Multiplex) signal. Described estimation algorithm is used in the DVB-T(H) (Digital Video Broadcasting - Terrestrial) receiver which can be used for navigation or for support of satellite navigation receivers. The last part of this paper describes our results of experiments with DVB-T(H) navigation. They were obtained in various environments (urban, suburban, etc.) including indoor environment.
