GPM Successfully Completes Performance and Functional Testing

An engineer stands in front of the GPM Core Observatory in the EMI testing chamber. GPM has successfully completed post-environmental Comprehensive Performance and Functional testing. These tests are performed to verify that the GPM Core satellite still meets all of its requirements after completing a suite of environmental tests (thermal/vacuum, electromagnetic interference/electromagnetic compatibility, vibration/acoustic/shock). The satellite is now being prepared for shipment to the HII-A launch site in Tanegashima, Japan.

GPM Completes Vibration Tests

The GPM Core satellite successfully completed vibration testing in July 2013, at NASA's Goddard Space Flight Center, Greenbelt, Md. The tests ensure that the spacecraft can withstand the vibrations caused by the Japan Aerospace Exploration Agency (JAXA) H-IIA rocket during satellite’s launch early in 2014. Sitting on a specialized mobile platform, the GPM spacecraft was abruptly moved back and forth in each of its three spatial orientations.

GPM Solar Array Deployment Test

GPM Solar Array Deployment Test
Friday, July 5, 2013
By Kasha Patel, NASA Goddard Space Flight Center Original www.nasa.gov Feature (published 7/1/13) NASA successfully completed two pre-vibration solar array deployment tests of the Global Precipitation Measurement satellite on June 6 and June 15, 2013. This video montage shows scenes from the test deployments of both GPM Core satellite solar arrays in a clean room at NASA's Goddard Space Flight Center in Greenbelt, Md., in June 2013.

The Observatory is now going through pre-vibration activities, including solar array deployments.

GPM Undergoes Electromagnetic Testing

The GPM Core Observatory is continuing with the environmental test program at NASA Goddard Space Flight Center. Following the completion of thermal vacuum testing in January 2013, the Core Observatory team started the Electromagnetic Interference (EMI) and Electromagnetic Compatibility (EMC) test phase. The Core Observatory has successfully completed the Radio Frequency (RF) Self-Compatibility test and is being prepared for the next step of EMI/EMC test program. The EMI/EMC test program is expected to be completed in April 2013.
