INDEX

- GEODESY- TECHNOLOGICAL ADVANCEMENTS- GLOBAL REFERENCES SYSTEMS- GNSS AND GRACE

INTRODUCTION

- Global reference system - ITRF- Ground stations and satellites- SLR and VLBI- Terrestrial measurements - Milimeter scale

IMPLEMENTATION OF GLOBAL REFERENCE SYSTEMS AND MODERN OBSERVATION

- GNSS- GRACE

GEODETIC STUDY ON EARTH SURFACE LOADING WITH GNSS AND GRACE

SEASONAL MOVEMENTS:- WATER- SNOW

The study of the Earth's surface and its loads... ∆g= local gravity∆M= mass changeG= gravitational constantr= distance

EXPANSION AND TECHNICAL DETAILS

CONCLUSION

- The development of geodetic methods... - The GRACE mission uses GNSS...
