Embodiment 1

[0030] One kind of embodiment of the present embodiment based location service Beidou Navigation system (e.g. figure 1 Shown), comprising:

[0031] Compass BD receiver module (i.e., the chip will be appreciated BDS and satellite antenna) for receiving a signal using the Beidou Satellite positioning a first antenna and outputting a first signal strength information and position information;

[0032] WIFI gateway module (i.e. WIFI module) configured to acquire the second positioning node using AP signal strength information and second position information;

[0033]The processing module (i.e., the chip), the first position information and second position information used to check whether the deviation exceeds a threshold, if exceeded, outputting the first position information; if exceeded, at time t based on the first signal strength information and a second signal strength information to build two vectors: a first intensity signal Sav1, a second signal strength WRV1, respectively, a...

Embodiment 2

[0043] A difference between this embodiment and embodiment of the present embodiment that the embodiment according to the present embodiment, the processing module further configured to, when the number of the RA SAV2 is above threshold, the WS sparse, CRV RA compressed vectors recombined preferred; CRV of vectors signal does not satisfy the threshold to form a new vector set GWV, using the signal amplifier GWV signal amplification; the GWV cross the CRV by probability distribution signal crossover probability distribution estimate, forming a balanced distribution of vector sets EDV; calibration coordinates is defined as CS (CRV, GWV, EDV), the CRV as the X axis, GWV Y axis, EDV Z-axis, a space calibration coordinate system; in the calibration coordinate system at an arbitrary Z-axis point to the corresponding X, Y-axis as parallel lines, the correction signal to obtain a triangular surface, thereby constructing a plurality of signal modifying surfaces, as excenter signal correcti...

Abstract

The invention relates to the technical field of positioning service, in particular to a position service system based on Beidou navigation technology. The system comprises a Beidou BD receiver module which is used for receiving a Beidou satellite signal by using a positioning antenna and outputting first signal strength information and first position information; a WIFI gateway module which is used for acquiring second signal strength information and second position information by using the AP positioning node; a processing module; and an auxiliary positioning module which is used for recording the WRV2 before change and the WRV21 after change to generate an AP positioning node change table when the user is switched from the indoor scene to the outdoor scene, then querying whether building exit positioning information corresponding to the AP positioning node change table exists or not, and if so, directly calling the corresponding building exit information as the current positioning information. According to the position service system based on the Beidou navigation technology provided by the invention, quick response can be realized after the use scene is switched, and the user experience is improved.

Description

Technical field [0001] The present invention relates to location service technologies, and particularly relates to a location based service system Beidou Navigation Technology. Background technique [0002] Beidou satellite navigation system, as China's major space infrastructure, positioning and navigation systems run independently through self-construction. Compass system has to provide all-weather, all-time advantage of standard and high-precision navigation and positioning services in so many areas have been successfully applied, their clients and services are gradually extended. [0003] With the development and popularization of mobile terminal positioning technology, location-based information services to users push more and more deeply into public life, such as a taxi, recommend businesses, nearby friends and so on. Location Services (LocationBasedService, referred to as the LBS), is achieved at the map technology, communication technology, network technology background p...
