Abstract :
An overview of the factors responsible in degradation of GPS (Global Positioning System) is described. Moreover, the major sources of error, their cause and how to reduce their effects are briefly discussed. Range errors such as ionospheric and tropospheric delays and equipment errors such as noise and multipath are separately explained. The latest developments in enhancing the quality of GPS technology are mentioned.
