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.
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.
The NASA Precipitation Measurement Missions (PMM) Science Team for the TRMM and GPM missions met on March 18-21, 2013 in Annapolis, MD. This meeting included oral, poster, and evening working group sessions covering mission/program status, algorithm development activities, international partner reports, science activities, field campaign results, and other science team business. More than 175 scientists from 11 countries participated. The TRMM satellite is now in its 16th year of on-orbit operation and the GPM Core Observatory is scheduled to launch in early 2014.
The 5th International Workshop for GPM Ground Validation (GV) hosted by Environment Canada was held on July 10-12, 2012, in Toronto, Canada. The primary objectives of the workshop were to improve understanding of high-latitude GV priorities and practices, identify and prioritize remaining issues with algorithm development, increase coordination amongst international partners, and improved understanding of how such information can be incorporated into GPM retrieval algorithms. Over 80 participants from 15 nations attended the workshop to report on cooperative ground validation activities
