Description
NASA has used satellite laser ranging (SLR) for almost two decades in the study of the earth. These include measurements of global tectonic plate motion, regional crustal deformation near plate boundaries, the Earth's gravity field, and the orientation of its polar axis and its rate of spin. The sub-centimeter precision of this technique is now attracting the attention of a new community of scientists interested in high resolution ocean, ice and land topography. The international SLR network is providing an essential link to two new oceanographic satellites, ERS-1 and TOPEX/Poseidon, which range to sea and ice surfaces using microwave altimeters.
