Variable Relevance for measuring this variable Operational limitations Explanation
Crustal motion (horizontal and vertical) 1 - primary Ground stations network needed.. Long time series needed. Dedicated satellite equipped by laser retroreflectors, specifically designed for space geodesy
Crustal plates positioning 1 - primary Ground stations network needed.. Long time series needed. Specifically designed system for space geodesy
Geoid 1 - primary Ground stations network needed.. Long time series needed. Dedicated satellite in very stable orbit optimal for describing the Earth's gravity field and geoid
Gravity field 3 - high Partial information (geoid). Dedicated satellite in very stable orbit optimal for describing the Earth's gravity field
