Session 12: Advanced Technologies II
Abstract
CE-SAT-I, the first technology demonstration satellite from Canon Electronics Inc. has been launched on June 23, 2017 from India by PSLV-C38. Canon is to enter small satellite industry to exercise its precision manufacturing, image processing and mass production capabilities as a new business sector. In this study, commercial DSLR camera, Canon EOS 5D Mark III has been proposed as a detector of the satellite with 40cm aperture, 3720mm focal length telescope aiming to capture 0.9m GSD from LEO. The satellite size is 50 x 50 x 80cm and 65kg in weight. Advantage of area sensor by applying commercial DSLR camera brings full HD and full color video, standardization and cost deduction capabilities. The sensor resolution is 5760 x 3840 pixels and the physical size of the sensor is 36 x 24mm. Point-and-shoot camera, PowerShot S110 is also equipped as wide angle camera as a finder of main telescope. Systems of CE-SAT-I has been developed based on commercial product of Canon. For instance, OBC has been developed based on same technology of multi-function printer. During initial operation, satellite health has been fully confirmed and optical calibration has been done with resolution test chart on the ground. Focus calibration has been performed with temperature control and physically adjusted by hyper-sonic actuator equipped on secondary mirror. Advanced missions are performed including video capturing, HDR, super-resolution and reprograming of OBC after initial operation. Ground stations has been developed and operated by Canon Electronics. The antennas are located around Tokyo and remotely operated. With the heritage of CE-SAT-I, Canon electronics is aiming to build a constellation of over 100 satellites with 8K low light real time video broadcasting with laser communication.
