  Global Positioning System (GPS) is a satellite network that transmits
regularly encoded information and makes it possible to pinpoint the exact
location on Earth by measuring the distance between satellites and the
receiver. While GPS satellites continually emit radio signals, receivers are
able to receive these signals. This study proposes a tool in which an
electronic circuit that is consisted of integration of SIM908 shield and
Arduino card is used as a GPS receiver. The positional data obtained from GPS
satellites yields error due to the noise of the signals. Accordingly, in this
study Kalman and Average filters are applied respectively in order to reduce
these faults and handle the overall positional error. Several experiments were
carried out in order to verify the performance of the filters within the GPS
data. The results of these enhanced systems are compared with the initial
configuration of the system severally. Especially the results obtained using
the Kalman filter is quite encouraging.
