APPARATUS AND METHOD FOR TRANSMITTING TERRESTRIAL DIGITAL MULTIMEDIA BROADCASTING SIGNAL FOR POSITIONING AND LOCATION MEASUREMENT METHOD USING THE SAME, AND POSITIONING SYSTEM USING TERRESTRIAL DIGITAL MULTIMEDIA BROADCASTING SIGNAL

摘要

1.The art that the present invention illustrates in detail in the claims;The present invention will be used to position in terrestrial digital multimedia broadcast singal transmitting device and method and positioning system uses and uses identical, a terrestrial digital multimedia broadcast singal in measure of location method. ;2.The present invention is to solve technical difficulty;The present invention is that when the terrestrial digital multimedia broadcast singal insertion of transmission of location information can measure one so-sending device receives his location information insertion terrestrial digital multimedia broadcast singal using the position of the own of that receiving device, and the earth provides a positioning system and uses the digital multimedia broadcasting signal first is that an object. ;3.The main points of solution of the invention,;The present invention, in transmission device, from from a broadcasting center transmission and neighbouring another transmission device terrestrial digital multimedia broadcast singal, signal demodulating equipment is for receiving signal transmission; Time synchronism apparatus is used to keep transmission device synchronous with remaining neighbouring signal sending time; Location information insertion apparatus, the location information (ID and unit information) and transmission device for being used for transmission transmission device are to other adjacent signal transmission devices; Wherein equally when by insertion from the synchronizing device of the location information of device, transmission time is synchronous with other neighbouring dosimeters, is used to from signal demodulating equipment insertion position information include sender unit for transmission to outside to terrestrial digital multimedia broadcast singal. ;4.Important use of the invention;The present invention is based on location service etc. yiyongdoem telematics services. ;Terrestrial digital multimedia broadcast singal, time synchronization, unit information, transmission device, relay apparatus, receiver, positioning system
