The invention relates to a navigation and location system and method. The navigation and location system includes multiple digital television transmitting stations which all transmit digital television signals carrying navigation information, and a receiver which receives the digital television signals of the digital television transmitting stations, measures the pseudo distance from each digital television transmitting station according to the corresponding digital television signal, and processes the measured pseudo distances through a three-satellite location algorithm to get navigation and location information. Compared with the prior art, the system has high signal intensity and strong anti-interference ability; and when the indoor environment or the satellite signal is blocked, the receiver can continuously receive digital television signals carrying navigation information and carry out navigation and location through the digital television signals carrying navigation information, and thus, the precisio
