High precision global positioning system data processing velocity vector determination for geodynamic application

Geodynamic studies involving Malaysia have been ventured upon in the South-East Asia region since the first GeodySEA project was carried out in 1996. For the fact that both East and West Malaysia lies on the same plate, we can assume that there will be no linear distortion for any two points joined...

For the fact that both East and West Malaysia lies on the same plate, we can assume that there will be no linear distortion for any two points joined relative to one another. In other words, for GPS observations over MASS stations, the baselines formed relative to any other MASS station can be roughly assumed to be constant without any significant changes.

This study will only look upon three years of MASS data from which most of the data were available simultaneously processed with 3 consecutive years of selected IGS. Since this movement is not evident for short observation or even observation of 1-year time span, therefore, a longer period of observation is needed to identify this movement.

At present the measures of quality for GPS derived coordinates given by commercial software packages tend to be unrealistic because unmodelled errors remain unaccounted for (Brown et al., 2002).
