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.
The 5th International Workshop for GPM Ground Validation (GV) hosted by Environment Canada was held on July 10-12, 2012, in Toronto, Canada.
The electrical integration of the GPM Microwave Imager (GMI) instrument onto the GPM Core Observatory was successfully completed in April 2012. In May, 2012, the Dual-frequency Precipitation Radar (DPR) instrument electrical integration was also successfully completed.
Congratulations to our partner, the Japan Aerospace Exploration Agency (JAXA), for the successful launch yesterday of the Global Change Observation Mission 1st - Water (GCOM-W1). GCOM-W1 carries the Advanced Microwave Scanning Radiometer 2 (AMSR2) which successfully deployed its antenna on orbit.
On March 30, the Japan Aerospace Exploration Agency (JAXA) officially handed off a new satellite instrument to NASA at Goddard Space Flight Center, Greenbelt, Md. The Dual-frequency Precipitation Radar (DPR) was designed and built by JAXA and Japan's National Institute of Information and Communications Technology (NTSpace).
The GPM Microwave Imager (GMI) instrument has arrived at NASA's Goddard Space Flight Center in Greenbelt, MD for integration into NASA's upcoming Earth science spacecraft. The instrument was built at the Ball Aerospace and Technologies Corp., Boulder, CO.

On January 30th and 31st, 2012, the GPM Microwave Imager (GMI) underwent its Pre-Shipment Review at Ball Aerospace in Boulder, Colorado. The GMI has successfully completed acoustic testing, vibration testing, and electromagnetic and thermal vacuum testing at the Ball facility. The instrument will be delivered to Goddard Space Flight Center on February 29th and will be integrated onto the GPM Core Observatory satellite over the coming year.

Japanese scientists and engineers have completed construction on a new instrument designed to take 3-D measurements of the shapes, sizes and other physical characteristics of both raindrops and snowflakes. The instrument will be shipped from Japan to NASA's Goddard Space Flight Center, Greenbelt, Md., to be integrated into an upcoming NASA Earth science satellite.

The GPM Cold-season Precipitation Experiment (GCPEx) to measure falling snow is currently underway in Ontario, Canada. The field campaign, which runs from January 17 to February 29, 2012, is designed to improve satellite estimates of falling snow and test ground validation capabilities for GPM.

GPM's two solar array wings that extend to the right (+Y) and left (-Y) of the spacecraft are currently undergoing assembly and testing at Goddard Space Flight Center, Greenbelt, Md. The solar arrays provide all the electrical energy for the satellite, and must survive flying in Earth's thin upper atmosphere at an altitude of 407 km (253 miles), where they will be subjected to small drag forces and exposure to corrosive atomic oxygen.
