In the recent years, object location becomes a major part of mobile devices and a lot of device services depend on the current location of the device. Also, there are applications like health care applications, need historical location data. Dealing with the historical location data will issue two main points: the first is a large storage space is needed for these data and the second is the desired location accuracy requirement should be defined. Ignoring these two points and storing the location data as it is received from the GPS sensor will result in west of storage resource because of data redundancy and over accuracy. This simple model deals with both redundancy and desired accuracy of the location data. After determining the desired accuracy for the latitude/longitude coordinate parameters, the system starts to code this set of location data using simple predictive coding scheme. This simple proposed method gives in some cases 1:25 compression ratio.
