Global NAVIGATION Satellite System Contribution for Observing the Tectonic Plate Movements: Status and Perspectives

The long-term monitoring of land movements represents the most successful application Global Navigation Satellite System (GNSS), particularly Positioning System. However, long term depends on availability homogenous and consistent daily position time series stations over a period time. Such can be produced very efficiently by using Precise Point Double Difference techniques based particular sophisticated GNSS processing softwares. Nonetheless, these rely products which are precise satellite orbit clock, Earth orientation parameters. Unfortunately, several changes modifications have been made periodically policy producing led to degradation in consistency For movements, it is essential that any such developments also used produce improved go back time, enable homogeneous reprocessing archived observation data. This paper deals with two main themes. Firstly, demonstrates significant imperative role geological applications addressing major global regional studies Earth’s deformation represent one geodesy. continues GPS measurements this highlighted discussed for modeling plate motions Glacial Isostatic Adjustment. Secondly, locates important obstacles stand behind inability use movements.
