Abstract: Advancement in satellites and telecommunication technologies has created a great interest in global positioning system (GPS) applications. The lack of a good geoid model for Jordan has limited the use of GPS applications. This has lead to refining the Jordanian geoid model for better GPS measurements in order to obtain reliable results in the triplet coordinates. The objective of this work is to present a practical method for Jordanian datums transformation, we order to be able to use directly a combination of local and global heights information (levelling data, local geoid model and global geoid models) for engineering applications. This method will resolve the height problem in GPS measurements and reduce the usage of levelling measurements. Our work is based on the implementation of all existing data such as level data and local/global geoid model data into software to directly transform GPS ellipsoidal height into normal height including datums transformation.
