Determination Altitudes using ROMPOS

Determination altitudes is a problem that cannot be perfect resolved because correlation between altitude and gravity. Determining of the (quasi) geoid disturbance is still a provisionally resolved problem in Romania and is in the attention of specialists. Currently ANCPI by ROMPOS service is providing this data. In the study presented shows that the determining altitudes is not punctual computed but by calculation to the reference station. Hence differences in the absolute altitude for the same point, determined from two different reference stations.
