Problems solved by technology

The disadvantage of this method is that it takes a long time for each experimental environment to manually collect a large number of experimental samples, and form a training database in advance, and the complexity of indoor and outdoor algorithms is very high, and the amount of calculation is large
Similarly, this method can only be used for a limited number of experimental scenes collected in advance. When encountering an unfamiliar environment, the classification error of this method is very large

Abstract

The invention belongs to the technical field of satellite positioning, and particularly relates to an indoor and outdoor state judgment method and system and electronic equipment. The method comprisesthe following steps: a, judging the number of visible satellites through a satellite existence search method; b, establishing a relation between the indoor and outdoor states and the number of the visible satellites, and judging the indoor and outdoor states according to the relation between the indoor and outdoor states and the number of the visible satellites. According to the embodiment of theinvention, the relation between indoor and outdoor states and the number of visible satellites is established, and the number of visible satellites is rapidly judged through the satellite existence search method, and the rapid judgment of indoor and outdoor states is achieved, the defects that an existing method is long in detection time and needs to train various environments are overcome, and satellite number judgment errors are reduced through a dynamic block averaging method.

Description

technical field [0001] The application belongs to the technical field of satellite positioning, and in particular relates to a method, system and electronic equipment for judging indoor and outdoor states. Background technique [0002] At present, a large number of mobile APPs need to obtain real-time location information of users to provide some location-based services (Location Based Services), such as finding nearby taxis, nearby restaurants, nearby shopping malls, etc. According to the survey results of the European Union's 2017 GNSS market report, more than 90% of location-aware apps rely on satellite positioning to obtain users' high-precision locations. [0003] In clear weather, satellite positioning can provide an average positioning accuracy of 10 meters. However, satellite positioning requires the user's mobile phone to perceive enough visible satellites, and usually only works outdoors to provide positioning. In indoor conditions (such as offices, shopping mall...
