Description: The Deep Space Communications and Navigation Systems Center of Excellence (DESCANSO) was established in 1998 by the National Aeronautics and Space Administration (NASA) at the California Institute of Technology’s Jet Propulsion Laboratory (JPL). DESCANSO is chartered to harness and promote excellence and innovation to meet the communications and navigation needs of future deep-space exploration. DESCANSO’s vision is to achieve continuous communications and precise navigation—any time, anywhere. In support of that vision, DESCANSO aims to seek out and advocate new concepts, systems, and technologies; foster key technical talents; and sponsor seminars, workshops, and symposia to facilitate interaction and idea exchange. The Deep Space Communications and Navigation Series, authored by scientists and engineers with many years of experience in their respective fields, lays a foundation for innovation by communicating state-of-the-art knowledge in key technologies. The series also captures fundamental principles and practices developed during decades of deep-space exploration at JPL. In addition, it celebrates successes and imparts lessons learned. Finally, the series will serve to guide a new generation of scientists and engineers.

Description: NASA QuikSCAT卫星使用散射仪（scatterometer ）测量海洋上的风速风向（自1999年至今），并公布于众。这是读取数据（L2B）的程序。数据可从http://podaac.jpl.nasa.gov/DATA_CATALOG/quikscatinfo.html查找和下载。可用于科研和海上风资源的调查研究。-SeaWinds on QuikSCAT measures backscatter from the ocean surface (sigma0) used to derive vector wind stress as well as wind speed and direction. Launched in June 19, 1999, QuikSCAT was originally intended to be a quick recovery mission to fill the gap created by the unexpected failure of the NASA scatterometer (NSCAT). Fortunately, QuikSCAT has surpassed its life expectancy and continues to provide reliable and valuable ocean surface wind vector measurements. These measurements are widely used for scientific research over a range of topics including oceanography, meteorology, sea ice, land-based studies, and wind energy. They also serve various needs of the private sector, educational community, and government.

Description: 精密单点定位(Precise Point Positioning, PPP)技术由美国喷气推进实验室( JPL ) 的Zumberge 于1997年提出。20世纪90年代末,由于全球GPS跟踪站的数量急剧上升,全球GPS数据处理工作量不断增加,计算时间呈指数上升。为了解决这个问题,作为国际GPS服务组( IGS)的一个数据分析中心, JPL提出了这一方法,用于非核心GPS站的数据处理。-Precise Point Positioning (Precise Point Positioning, PPP) technology by the U.S. Jet Propulsion Laboratory (JPL) of the Zumberge made in 1997. 90' s at the end of the 20th century, the global GPS tracking sharp rise in the number of stations, the global GPS data processing ever-increasing workload, an exponential increase in computing time. To solve this problem, as the International GPS Service (IGS), a Data Analysis Center, JPL proposed this approach for non-core data-processing of GPS stations.
