Its camera mission is to take pictures of Sri Lanka and its neighboring countries. Its Lora Demonstration Mission is to validate the module/to be used to data download next satellites. The Attitude Determination and Control Mission of ‘Ravaana 1’ involve the team trying to reduce the angular velocity of the satellite using magnetic torquers. Sri Lanka’s first satellite Raavana 1 was launched successfully into space yesterday from NASA’s Wallops Flight Facility on Virginia’s East Shore.
