Editing CASSIOPE (section)

===Cascade===
The commercial payload, named Cascade, is a [[technology demonstration|technology demonstrator]] courier in the sky, aimed at providing a [[proof of concept]] for a [[digital data|digital]] [[broadband]] courier service for commercial use.  Built by MDA, the operational concept is to receive very large data files as the satellite orbits the globe, [[digital storage|store]] them onboard temporarily, then deliver them at a later time to nearly any destination worldwide.<ref name=pa20130910/>

The demonstrator will provide a secure digital [[store and forward|store-and-forward]] file delivery service, exploiting the fact that CASSIOPE passes over much of the globe 15 times per day.  It has been described{{by whom|date=September 2013}} as a courier service, with the customers using a small parabolic antenna of one or two meters (three or six feet) to upload or download files at a rate of 1.2 gigabits per second. The storage capacity will be between 50 and 500 gigabytes and the data delivery time will be about 90 minutes, depending on the pickup and deposit points on the globe.{{citation needed|date=May 2013}}
