Positioning method for indoor and outdoor environment seamless switching realized by global navigation satellite system (GNSS)-based fingerprint positioning technique
TLDR
In this article, a positioning method for indoor and outdoor environment seamless switching realized by global navigation satellite system (GNSS)-based fingerprint positioning technique, relates to the technical field of satellite positioning and navigation.Abstract:
The invention discloses a positioning method for indoor and outdoor environment seamless switching realized by global navigation satellite system (GNSS)-based fingerprint positioning technique, relates to the technical field of satellite positioning and navigation, and solves the problem that for the positioning service under the indoor and outdoor environments, seamless positioning switching is difficult to realize under indoor and outdoor environments because a user needs receivers in indoor and outdoor systems at the same time By the positioning method, N GNSS fingerprint positioning nodes are introduced indoors; information frames of the GNSS fingerprint positioning nodes consist of positioning information frames and information frames for location based service (LBS); during positioning, when the positioning is realized by an outdoor positioning way, if the number of visible satellites which participate in the positioning is less than 4, the positioning is switched to an indoor fingerprint positioning way; and when the positioning is realized by the indoor fingerprint positioning way, if that the user leaves the indoor environment is judged, the positioning is carried out in the outdoor positioning way The positioning method is suitable to be used in the field of the satellite positioning and navigationread more

Positioning Method and Apparatus
Huang Qing,Qiu Zeling +1 more
TL;DR: In this article, the authors proposed a positioning method for switching between indoor and outdoor positioning systems, where the satellite information providing the outdoor positioning service satisfies a pre-set condition, and the terminal attempting to acquire an indoor positioning result via an indoors positioning service, the pre-sets condition being used to indicate that the terminal has an indoor position requirement.
Patent
Indoor positioning method based on inverse GNSS node
TL;DR: In this paper, an indoor positioning method based on an inverse GNSS node relates to a seamless positioning technology, where indoor nodes are used to emit a reversely-deduced GNSS signal to defraud a GNSS receiver so as to enable the receiver to get a preset positioning result.
