Abstract

This paper proposes a method for the predictionofGPS data using Normalized Least-Mean-Square Algorithm (nlms) was used as application of adaptive filter.Fourdifferent scenarios were taken to predict the GPS data.Thefirst one was without blocking of data and the three others with blocking for (3, 6, and10 seconds,respectively), with implementation in MATLAB. The prediction process of the GPS receivers is required for different reasons, such as maneuvering, founding obstacles, and also the time of booting may be too long due to the difficulty inobtaining the satellite’s position,hencein such casesone can use the GPS prediction data in order to solve these problemsand reduce the booting time and avoid losing of the GPSdata for any reason.
