摘　　要：基于地理位置信息的商业服务具有巨大的商业价值和市场潜力,而目前定位服务主要针对于室外场景的定位,包括诸如GPS导航,微信,滴滴等一系列应用软件,然而,随着无线通信网络和移动互联网的发展,基于无线通信基站的室内三维定位将具有重要意义.利用2016年全国研究生数学建模竞赛所给测试数据,采用将多维搜索简化为分步一维搜索方法,将非线性方程组的最小二乘问题转化为线性方程组的最小二乘问题,在全域内搜索转化为在窄域内搜索等技术,在获取终端坐标以及移动轨迹方面取得了满意结果.The commercial service based on location information has great commercial value and market potential. But at present, the main needle positioning services are mainly for outdoor scene positioning, in- cluding a series of applications such as GPS navigation, We Chat, Drops Taxi and so on. However, with the development of wireless communication network and mobile Internet, indoor 3D localization based on wireless communication base-station will be of great significance. In this paper, the test data is given by the national graduate student mathematical modeling contest in 2016, adopting the methods; multidimen- sional search is simplified as a step-by-step dimension search; the least squares problem of the nonlinear e- quations is transformed into the linear equations, and global search is transformed into narrow domain search. Finally, satisfactory results have been obtained in the acquisition of the terminal coordinates and trajectories.
