Aerojet Rocketdyne gives boost for global precipitation measurement satellite

28 February 2014

Aerojet Rocketdyne, a GenCorp (NYSE: GY) company, said it provided propulsion for NASA´s global precipitation measurement core observatory satellite, launched from JAXA´s Tanegashima Space Center in Japan aboard a Japanese H-IIA rocket.

Once separated from the launch vehicle, the GPM satellite uses 12 Aerojet Rocketdyne MR-106L 5.0 lbf monopropellant thrusters for attitude control.

The GPM core observatory is an international satellite designed to provide advanced observations of rain and snowfall worldwide, several times a day to enhance scientists´ understanding of the water and energy cycles that drive Earth´s climate. The data will be used to calibrate precipitation measurements made by an international network of partner satellites to quantify when, where and how much it rains or snows around the world.
