A mobile device 5 is disclosed for receiving navigation signals 51a-c, 52a-c, from satellites 11a-c, of a first global navigation satellite system (GNSS) 1, having a first reference clock 100, and from satellites 21a-c, of a second GNSS 2, having a second reference clock 200 respectively. The mobile device is arranged to receive a timing signal 54 from a transmitter 4 at a terrestrial location, the timing signal comprising data indicative of a time difference between the first and second reference clocks 100,200. The mobile device generates an indication of a location of the mobile device based on the received timing signal 54 and a plurality of navigation signals received from a corresponding plurality of satellites including at least one satellite from each GNSS. |
