LOCATION INFORMATION TRANSMITTER, COMMUNICATION TERMINAL, AND POSITIONING SYSTEM

摘要

PROBLEM TO BE SOLVED: To suppress positioning errors from becoming large and prevent an increase of a positioning time, by overcoming problems of null points or interference of signals concerning a location information transmitter installed indoor in a positioning system for acquiring current locations of both of outdoor and indoor.

SOLUTION: A location information transmitter 2 for informing location specified by location data in a communication terminal receiving location information signals having a satellite positioning signal which is a wireless signal for positioning transmitted from an artificial satellite and compatibility, and having a wireless transmitting part repeating transmission through an antenna of the location information signal which is the wireless signal including location data indicating a specific location has a plurality of mutually separated antennas 28. The wireless transmitting part transmits the location information signal including the same location data parallel in respectively different channels in each antenna 28 or transmits to be time-divided in the unit of the antenna 28 in arbitrary channels.
