Abstract: |
With frequency channels expansion, device renovation of GPS and GLONASS, and the deployment of new satellite navigation such as CNSS, QZSS and EGNOS, the out-door positioning technology has become a mature technology. However, the restriction of light of sight still affects the accuracy of indoor positioning, especially in a city with crowded buildings. Thus, the widely deployed IEEE 802.11 wireless local area networks are utilized to be an in-door positioning solution. Unfortunately, the inaccurate location results frequently confuse the positioned devices or users about their precise location. As a solution, we propose a novel indoor-positioning solution which aims to obtain precise position for those non-real-time positioning applications such as equipment property monitoring, fixed wired/wireless sensors and so on. The concept of this paper is using long-term measured results to solve the issue of instable signal strengths and derive precise location of monitored devices.
