Requirements Description : The DNS is a critical sensor used to provide highly accurate , three - dimensional velocity and navigation data on the AH - 64D / E Longbow Apache helicopters . The DNS is integrated into the Apache Global Positioning System ( GPS ) and Inertial Navigation System ( INS ) to provide independent , jam - resistant navigation and enables these systems to operate effectively and dependably , day or night , and during adverse weather conditions and when GPS is not available . It provides accurate 3 - D velocity data for fire - control , INS aiding , weapons delivery , and hovering operations . The use of helicopters without a fully functional DNS would present safety risks to the pilot , the supported Warfighter , and would prevent completion of missions . Repair support is a critical and essential element for supporting the helicopter fleet and to ensure these items are maintained in an operational condition . The acquisition of hardware spares is also crucial in the sustainment of fleet operation . The Government does not possess the technical data package ( TDP ) for the parts .
