Application of Least Squares Algorithm for Precise GPS Receiver Positioning

Precise positioning measurements of Global Positioning Systems (GPS) have revolutionized scientific research in the area of geodynamics. Nowadays, it aids in the study of the crustal deformations caused by earthquakes, the unavoidable natural disasters. Calibration of the GPS data over fault lines, epoch-by-epoch results in precise positioning of the receiver. Least squares method is implemented in the calculation of the receiver coordinates obtained from the pseudoranges for every epoch. Application of this method has given a good approximation of the receiver coordinates at a given location.
