For the past three years, the Global Precipitation Measurement (GPM) Core Observatory has gone from components and assembly drawings to a fully functioning satellite at NASA's Goddard Space Flight Center in Greenbelt, Md. The satellite has now arrived in Japan, where it will lift off in early 2014.
GPM Instruments Undergo Pre-Ship Review
GMI Pre-Ship Review On January 30th and 31st, 2012, the GPM Microwave Imager (GMI) underwent its Pre-Shipment Review at Ball Aerospace in Boulder, Colorado. The GMI has successfully completed acoustic testing, vibration testing, and electromagnetic and thermal vacuum testing at the Ball facility. The instrument will be delivered to Goddard Space Flight Center on February 29th and will be integrated onto the GPM Core Observatory satellite over the coming year. This multi-channel, conical-scanning, microwave radiometer will provide an integrated view of precipitation over 13 different microwave

Spaceborne Precipitation Radar Ships from Japan to U.S.
By Aries Keck, NASA Goddard Space Flight Center Original www.nasa.gov Press Release (published 2/8/12) GREENBELT, Md. – Japanese scientists and engineers have completed construction on a new instrument designed to take 3-D measurements of the shapes, sizes and other physical characteristics of both raindrops and snowflakes. The instrument will be shipped from Japan to NASA's Goddard Space Flight Center, Greenbelt, Md., to be integrated into an upcoming NASA Earth science satellite. Designed and built by the Japan Aerospace Exploration Agency (JAXA) and Japan's National Institute of Information
GPM Core Observatory, Integration and Testing
Each time a new component is added to the spacecraft, rigorous testing is conducted to ensure the new components operate correctly and work effectively with existing systems.
