Problems solved by technology
However, it has been found in practice that when the user turns on the GPS module in the user terminal for navigation, the GPS often loses satellites during the navigation process. For example, the number of satellites searched by the GPS module drops from 10 to 0. The GPS module cannot locate the user terminal, usually the user needs to manually restart the GPS module to achieve positioning
If during the navigation process, there are a lot of GPS star drops, the user needs to manually restart the GPS module many times to achieve positioning, which makes the efficiency of GPS positioning low

The embodiment of the invention discloses a global positioning system (GPS) starting method and user terminal. The GPS starting method includes the steps of a GPS module searching satellites to obtain a first GPS satellite list for storing first satellite signal information when the GPS module is under an on state, determining whether the GPS module is currently under an ineffective positioning state according to the first satellite signal information, and restarting the GPS module if the GPS module is currently under an ineffective positioning state. The GPS positioning efficiency can be improved.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a method for starting a global positioning system and a user terminal. Background technique [0002] The Global Positioning System (GPS) is a medium-distance circular orbit satellite navigation system. GPS can provide accurate positioning, speed measurement and high-precision time standard for most of the earth's surface. With the maturity of GPS technology, more and more user terminals (such as smart phones) are equipped with GPS modules, which brings great convenience to users' lives. However, it has been found in practice that when the user turns on the GPS module in the user terminal for navigation, the GPS often loses satellites during the navigation process. For example, the number of satellites searched by the GPS module drops from 10 to 0. The GPS module cannot locate the user terminal, usually the user needs to manually restart the GPS module before positioning ...
