Abstract	The degree of accuracy and availability of service make a distinction between the two main methods of geolocation that areGPS and UMTS. GPS provides good performances in terms of location in open area, but performances degrade to a significant manner when we go into an enclosed area. While the UMTS offers good results in urban areas, we can note a complementarity between these two techniques. In this paper we present a hybrid algorithm that combines these two techniques and takes best advantage of each of them with two approaches one simple and another advanced.
