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.
