Engineers working on the GPM Core Observatory
By Ellen Gray , NASA Goddard Space Flight Center Original www.nasa.gov Article (published 10/17/12) NASA's Global Precipitation Measurement (GPM) Core Observatory satellite went through its first complete comprehensive performance test (CPT), beginning on Oct. 4, 2012 at NASA's Goddard Space Flight Center in Greenbelt, Md. The testing ran twenty-four hours, seven days a week and lasted ten days as the entire spacecraft was put through its paces. "This is the first time we've gotten to see the observatory all put together, running the way it's supposed to be running in flight," said CPT Test...

GPM Microwave Imager (GMI) Testing

The GPM Microwave Imager (GMI) successfully completed a walkout deployment, spin-up and functional and interface testing after being integrated onto the core spacecraft in May, 2012. These series of tests confirmed electrical and functional performance of the GMI with the GPM Core Observatory. The GMI undergoing mechanical integration in March 2012.

The electrical integration of the Global Precipitation Measurement Microwave Imager (GMI) instrument onto the GPM Core Observatory was successfully completed in April 2012. Ball Aerospace and Technologies Corp. Boulder, Colo. built the GMI, which arrived at NASA's Goddard Space Flight Center in Greenbelt, Md. in early March and after post shipment processing it was handed over to NASA. The GMI is one of the key instruments for the GPM Core Observatory. This instrument is a passive radiometer with 13 channels covering frequencies from 10 to 183 GHz. In May, 2012, the Dual-frequency...
