Tropospheric Products from High-Level GNSS Processing in Latin America

Mostrar todas las versiones(2)

The present geodetic reference frame in Latin America and the Caribbean is given by a network of about 400 continuously operating GNSS stations. These stations are routinely processed by ten Analysis Centres following the guidelines and standards set up by the International Earth Rotation and Ref...
