The invention provides a positioning service method and system based on a high-precision base reinforcing system. The method is that a protocol format supported by a common precision receiver can be converted after obtaining high-precision positioning differential data, the obtain positioning differential data recognized by the common precision receiver is sent to the common precision receiver, and therefore, the common precision receiver can obtain the high precision positioning differential data from the positioning differential data to be recognized; the high precision positioning differential data are utilized to position, so as to improve the positioning precision of the common precision receiver; the applicable scope and degree of the high precision positioning service can be expanded, and as a result, the application scope and degree of a Beidou satellite navigation system can be further expanded.
Description
technical field [0001] The present invention relates to the technical field of a high-precision ground-based augmentation system of a global navigation satellite system, and more specifically, relates to a positioning service method and system based on a high-precision ground-based augmentation system. Background technique [0002] As one of the most promising high-tech fields in the world today, the Global Navigation Satellite System (GNSS, Global Navigation Satellite System) is an important symbol and a concentrated expression of a country's comprehensive national strength, core competitiveness and technological innovation capabilities. China's Beidou (Compass or BeiDou) satellite navigation system, together with the United States' Global Positioning System (GPS, Global Positioning System), Russia's GLONASS (GLONASS) and Europe's Galileo (Galileo) system, are known as the world's four major GNSS , the basic positioning principles of these four major GNSS are exactly the sa...
