Abstract
This paper describes what we believe is a disruptive technology solution for smallsat optical imaging missions, that combines a new line of cameras that provide very high quality, high resolution imaging, with a low power Payload Controller, Processor and Memory Unit (PCPMU) that provides multi-terrabit on-board data storage and high speed data output at a uniquely low price point. Working together with the Rutherford Appleton Laboratory in the UK, MDA is developing the RALCam family of high resolution multispectral cameras, capable of up to 0.5 m GSD imaging from a 500 km altitude. Two related camera systems in the product family are described, one that provides 1.0 m GSD and the other that provides 0.5 m GSKey performance specifications for both cameras are given. Hardware testing results are also summarized. MDA are incorporating these cameras and payload electronics into a highly price competitive mission level solution that includes a spacecraft designed and optimized specifically for the RALCam high resolution cameras and a full ground segment that includes the satellite control & tasking, uplink and downlinks, and image processing and archiving which produces very high quality image & information products. MDA’s optical spacecraft design that incorporates the RALCam high resolution cameras is also described and key performance parameters are given. Finally, concluding remarks are provided that summarize the key technology and price point enablers. The first system could be launched as early as 2010 and we expect this will change the economics of operational class high resolution optical remote sensing.
