Spot on Justin. Documentation is still a little scarce and what we have (requirements specifications, etc.) may be hard to interpret. What exists to date is a boresight single beam system, soon to be upgraded to the four beam system Justin mentioned. We are open to setting up calls to discuss though - maybe after our big end of March milestone...
