The Design And Implementation Of High Resolution Location System Based On GPS And UWB

In recent years,with the gradual maturity of wireless positioning technology,the location services industry develops rapidly,such as wisdom of city construction,Internet of things,weather forecast,disaster mitigation and disaster relief.CurrentlyGPS has a very wide range of applications in outdoor situation,but for indoor envioronment,it still can't have accurancy positioning.Currently,there are many commercial location productions,all the productions have their own specificcharacteristic such assomeone's price is low,but its resolutions is also low,and in indoor environment covering area is small.Ultra-wideband(UWB)has following advantage such as high accuracy location,anti-multipath capability and strong penetrating power.Based on this advancedtechnology,UWB can be used as a key solution in high accuracy location in indoor situation.This paper raise a common situation based on the requirements of market: use different high accuracy technology in different envioronment and also the cose must be took into consideration.This paper givesoneproper location solution with in-depthresearch of current requirement.This paper includes content as following:1.After comparison of widely used wireless localization technologies,design and implement a location engine based on GPS and UWB.This location engine is scalable,2.Implement a location system based the locate engine.
