Abstract

Provided is an assisted enhancement navigation method and device. The method includes receiving a GNSS satellite signal and locating itself according to the GNSS satellite signal to obtain the original PVT data of the low-orbit satellite itself, wherein the GNSS satellite signal includes a GNSS satellite navigation message, and the original PVT data includes the original location, the original speed and the original time; making precision of the original PVT data by means of a track precision algorithm to obtain the precision PVT data; processing the precision PVT data and the GNSS satellite navigation message to generate a navigation assisted enhancement message signal; and broadcasting a low-orbit satellite signal containing the navigation assisted enhancement message signal for the navigation of a ground terminal. The assisted enhancement navigation method and device provided by the invention improve the precision of navigation.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to an auxiliary enhanced navigation method and equipment. Background technique [0002] Global Navigation Satellite System (GNSS), including in particular the US Global Positioning System (GPS), the Russian Global Navigation Satellite System (GLONASS), the European Galileo system (Galileo) and the Chinese Beidou The four core navigation systems (Compass, BDS) are the basis of various radio positioning technologies. GNSS can provide users with all-weather navigation and positioning services around the world, and its application prospects are very broad. However, with the advancement of its navigation and positioning technology and the expansion of its application fields, some special occasions put forward higher standard requirements for its positioning accuracy, anti-interference ability, response speed, sensitivity, etc., such as cities, indoors, forests, etc. In various comple...
