Abstract

Because single GPS technology cannot realize localization in a dense urban environment, and in view of Chinese digital television terrestrial broadcasting (DTMB) signals using with fixed transmitters, wide coverages, high positioning accuracy, and low cost, this paper suggests a location method based on DTMB. Because the observation model of the DTMB’s location system is gauss non-linear, this article contrasts and analyzes the tracking effect of two kinds of environment: a line-of-sight (LOS) environment and a non-line-of-sight (NLOS) environment. Simulation results show that: the tracking trajectory is in line with the true trace, due to the interference of the NLOS environment; the error of NLOS is bigger than LOS; and the tracking accuracy of NLOS is better than LOS. This all proves the feasibility and superiority of a location system based on DTMB.
