Yes, that is true, so are these licensed under an authority other than amateur radio ? If they aren't then my questions stand.

What is the chipping rate/bandwidth of these? Don't the PRN sequences need to be made public so as not to be classified as "encryption" ? Detailed specs on the Sprites is in short supply. Has anyone done a link budget, seems like allot of spreading gain is required to hear 10mW form a 300km orbit which translates into allot of bandwidth in a part of the band usually reserved for narrow band modes. The lack of transparency on many of these projects that use the amateur bands seems to run against the spirit of amateur radio in my opinion.
