Abstract
Disclosed is a method for transmitting pseudolite system messages, the method including: pseudolite sends pseudolite node parameters of the pseudolite to which a positioning system messages broadcast channel belongs, and pseudolite node parameters of the pseudolite adjacent or nearby to the pseudolite to which the positioning system messages broadcast channel belongs, in the configured positioning system messages broadcast channel. A method for transmitting indication message of the positioning system messages broadcast channel is also disclosed in the present invention, the method including: a wireless access point sends an indication message of the positioning system messages broadcast channel of the pseudolite to a radio positioning terminal in its service area. According to the indication message of the positioning system messages broadcast channel, the radio positioning terminal accesses corresponding the positioning system messages broadcast channel, and surveys the positioning signal and/or positioning based on the node parameters obtained from the positioning system messages broadcast channel. A pseudolite positioning system and associated device are also disclosed in the p…
