A Practical Location Scheme Based on GSM Cellular System

Recently, many manufacturers and operators have focused on the research and applications of location techniques in GSM. In this paper, a GSM position location simulator and a new method for locating GSM mobile station using CGI+TA are presented. A hybrid algorithm is proposed, which is based on one time advance together with several Relevel measurement. Computer simulations are provided to show the accuracy of the proposed approach in various environments.
