The Nanook is a modified ScanEagle, which uses the Piccolo autopilot to reduce its operational footprint and increase its capabilities. ACUASI performed these modifications after observing the challenges and short-comings of the stock ScanEagle systems when operating in the arctic. Based on these observed needs, ACUASI engineers installed the Piccolo autopilot, converted from a carbureted fuel system to a fuel-injected system, and made a number of smaller modifications for improved operation in the cold temperatures characteristic of the arctic and sub-arctic.
