The AeroCube 11 (AC11) or R3 spectral satellite is a multispectral, pushbroom imager that flies the Landsat-8 visible bands in a 3U Cubesat package.
It will demonstrate the utility of CubeSats to perform remote-sensing missions at a performance level comparable to that of larger spacecraft. The bus includes a 2.5-cm-diameter telescope paired with a visible-light sensor, 3-axis attitude control, 8 GB of image storage space, and a laser transmitter to downlink the images at a very high rate (up to 200Mbit/sec). The project began in mid-2014 and will be delivered in mid-2017, to be launched into a 500-km, 85-deg inclination circular orbit. With a ground sample resolution of 40 m and a field of view close to 50 km, the payload will produce data useful for agricultural and mineral surveys and coastal water quality monitoring, among other applications.
