Triana II a new constellation of operational earth remote sensing satellites

摘要

Understanding the earth's climate and the how it supports life is essential to government policy makers. A new constellation of operational earth remote sensing satellites (Triana II) is required to provide data to develop this understanding. Comparison of several spacecraft, sensors systems, orbits, and constellations is described and one recommended that will support many of the policy decisions facing governments around the world over the next critical decades.
