The High Gain Antenna System onboard the GPM Core Observatory was successfully deployed and functionally tested after being integrated onto the spacecraft late last year. The HGAS is responsible for relaying data collected by the satellite’s instruments to Tracking and Data Relay Satellite System (TDRS) satellites.  Data is sent back to Goddard Space Flight Center via a NASA wide-area network.
