Positioning with GPS can be realized two main ways: i-Single Point Positioning (SPP), ii- relative positioning. When the high accuracy is required, the accuracy obtained from SPP is not enough and for those applications relative positioning method have to be considered. However in this method, there should be at least two receivers to collect the data and software to process these data.

Archaeology reflects the amazing diversity of human life across the globe (Neto, 2000). Archaeological investigations are considered as a principal source of knowledge of prehistoric, ancient, and extinct cultures. In order to reconstruct history, archaeologists rely on all the unearthed evidence, such as man-made objects, which can be as small as tools and ornaments or as large as architectural residues (Xia, 2006).

Location Base Services (LBS) is service mechanisms that provides information about the location and take advantage of the location. Global Positioning System (GPS) is one of Devices that inform the position. Mobile phone GPS has the advantage because they can be used also as a means of communication and the completeness of the camera (photo and video) resolution good enough to take photos that have coordinates ((Geo)tagging photo) and can be sent directly to the office for more information .
