Ny-Ålesund, Norway

Location of Ny Alesund site on a globe.

A significant activity is taking place at the Norwegian Mapping Authority's Ny-Ålesund Geodetic Observatory in Svalbard, Norway. NASA is making progress in the development of a new satellite laser ranging system (SLR) at the observatory. SLR is fundamental to precisely determining the position of retro-reflector equipped satellites which in turn provides important information into the generation of the International Terrestrial Reference Frame and an understanding of where everything is. The measurements made from SLR systems around the world are helping countries make informed decisions about climate, sea rise, and other important major changes that are affecting the Earth.
