Description

487806 V. Description of the invention (1) The present invention relates to a method and system for using GPS satellite positioning, especially using broadcast GPS satellite ephemeris data (Ephemer is) and Doppler frequency shift (D ο pp 1 ershifts), so that The mobile unit can quickly and effectively obtain such data for positioning, and use the location information obtained by the mobile unit to provide the queryer to query the location or to confirm the location of the person to be rescued. At present, some cars are equipped with a GPS satellite navigation system. Using GPS receivers to receive information transmitted by at least four visible and unobstructed satellites can calculate their location. However, it is difficult to use traditional GPS receivers to receive GPS satellite signals for positioning in urban areas, because they are blocked by buildings, or indoors, because the GPS satellite signals received are relatively weak. In addition, because GPS satellites transmit ephemeris data and GPS satellite locators search satellite signals very slowly, it takes a long time for GPS satellite locators to fully receive sufficient positioning data. Generally, it takes about 3-10 minutes for the satellite locator to complete the positioning work when the receiver is well cold-started, and it takes about 1 minute for positioning in the warm-up state. Because of the long positioning time, it also consumes considerable power. FM broadcasts GPS satellite differential correction (Differential c 0 r r e c t i ο η) data for many years, the differential correction data can make GPS positioning more accurate. However, due to US policy adjustments this year, GPS positioning has been made more accurate, and its accuracy has been reduced from the original 100 meters to 25 meters without the need for differential correction. Therefore, the use of the differential correction data of the GPS broadcast GPS satellites has no substantial benefit. (Also related to the GPS satellite positioning processing system, for example, U.S. Patent No. 5, 8 7 4, 9 1 4 discloses the use of mobile station communication network base stations to transmit GPS satellites.

However, these GPS satellite positioning architectures using mobile phone systems require new adjustments to the hardware equipment of the mobile phone system, which can take a considerable amount of money to complete, and need to integrate the mobile phone systems of different mobile phone operators, which is quite feasible. difficult. Also U.S. Patent No. 6,0 6,7,0 5 discloses a use of a GEM (Geo-Mobile, satellite phone) satellite system to enable a mobile unit to quickly obtain positioning data, but its applicable range is up to 100 km , The original data required for its positioning, such as the Doppler frequency shift, may not be applicable in this long range. In order to improve the positioning time of the conventional traditional portable GPS satellite locator, it takes a long time, consumes battery power, and often encounters poor reception and cannot locate the situation. The patent case reveals that the existence of each mobile unit positioning system requires high costs, it is not easy to integrate various mobile phone systems, and the mobile unit reception situation is still not satisfactory. After repeated research by the inventor, the present invention was finally completed. The main object of the present invention is to provide a positioning method and system for broadcasting GPS satellite positioning information by using a broadcasting station. Since the broadcasting system has uniform specifications and the broadcasting frequency has strong penetration, the setting of the GPS positioning system of the mobile unit is easier It is integrated, more cost-effective, and has better reception status.
