High performance (AVStar Narrow Field and Wide Field Cameras)
Astrovision is a commercial remote sensing company that is launching a series of
spacecraft to provide color imagery of Earth from geosynchronous orbit. To meet their
requirements for both high quality and high frame rate (compared to existing
geosynchronous systems), MSSS designed the AVStar electronics system based on a 2K
x 2K format interline transfer (electronically shuttered) CCD. As can be seen from the
test image below, this large format can provide high resolution over a wide field of view.
