Remote Interface Units (RIU): Remote Interface Units (RIUs) are designed for remote locations and communicate with higher-level computing systems such as Flight Control Computers (FCC) and Mission Computers (MC), gathering, analyzing and sending data throughout the platform. These Modular Open Systems Approach (MOSA) systems feature different analog and digital input and output modules that can be used with a wide range of function types including AC excitation, LVDT, variable reluctance, thermocouples, and RTDs. NAI’s rugged AIU systems offer a DO-178C & DO-254 Certifiable solution and are ruggedized to withstand -40° C to +71° C and qualified to MIL-STD-1275D & MIL-STD-704A with 50 ms holdup (power supply); MIL-STD-461F & MIL-STD-810G.

Data Acquisition Systems: Data Acquisition (DAQ) systems are used to collect information for the purpose of documenting or analyzing an electrical or physical phenomenon, for example: temperature or pressure. They serve as a focal point in tying a wide variety of sensors together that indicate temperature, flow, level or pressure. The sensors convert a physical occurrence into a measurable electrical signal, which can be factored into command and control decisions. These high-speed DAQ systems feature different analog and digital input and output modules that can be used with a wide range of signal types including 4-20 mA current, thermocouples, and RTDs. NAI’s rugged DAQ systems offer a proven solution for acquiring information in real time and are ruggedized to withstand -40° C to +71° C and qualified to MIL-STD-1275D & MIL-STD-704A with 50 ms holdup (power supply); MIL-STD-461F & MIL-STD-810G.

Fire Control & Targeting Systems: NAI’s high-performance Fire Control & Targeting (FCT) systems can be applied to a spectrum of applications where a multitude of sensor and command interfaces need to be maintained to ensure steady on-target aim and control. Critical air, land or sea positioning platforms such as on-the-move targeting or line-of-sight communications, radar and laser guidance can benefit from the efficient and programmable NAI FCT systems. NAI’s rugged Fire Control and Targeting systems perform with a high level of stability and accuracy are ruggedized to withstand -40° C to +71° C and qualified to MIL-STD-1275D & MIL-STD-704A with 50 ms holdup (power supply); MIL-STD-461F & MIL-STD-810G.

Integrated Vehicle Health & Monitoring Systems: Integrated Vehicle Health Monitoring (IVHM) systems combine a range of diagnostic tools within a single platform and provide around-the-clock, intelligent diagnostics on critical mission, air, land and sea applications. NAI’s Integrated Vehicle Health & Monitoring systems employ a range of device interfaces that support a myriad of sensor inputs and perform intelligent sensor monitoring of military vehicles on critical missions. IVHM systems enable the collection and transmission of information regarding a vehicle’s status, condition, and performance. This provides early warning maintenance signals, enhances vehicle safety, reduces manpower and maintenance costs, and improves vehicle readiness. NAI’s rugged IVHM systems offer proven solutions and are ruggedized to withstand -40° C to +71° C and qualified to MIL-STD-1275D & MIL-STD-704A with 50 ms holdup (power supply); MIL-STD-461F & MIL-STD-810G.

Remote Data Concentrators: Remote Data Concentrators (RDC) process and format aircraft sensor data into a common digital format over MIL-STD-1553, RS-422 and ARINC-429 protocols, which can then be received by avionics computers and cockpit displays that require engine/aircraft sensor data in a digitized form. RDCs often serve as the "central nervous system" for most avionics equipment on an aircraft and host the avionics and utilities functions, eliminating several boxes and hundreds of pounds of cable. NAI designs remote data concentrators around core COTS technology building blocks, offering our customers readily available, interoperable, field-proven systems (or subsystems) designed to withstand the rigors of harsh, SWaP-constrained environments where compact, low-power systems are required.

Vehicle Management Systems: Vehicle Management Systems (VMS) are used to perform a multitude of functions on critical military platforms including manned and unmanned military aircraft, helicopters, shipboard vessels, autonomous missile systems and military ground vehicles, and function as the core control element within a redundant control system. A single VMS solution can perform functions such as vehicle stability and control, guidance and navigation and more by collecting, packaging and transmitting local discrete, analog and digital data inputs and can control local functions based on received data. NAI’s rugged VMS systems offer proven solutions and are ruggedized to withstand -40° C to +71° C and qualified to MIL-STD-1275D & MIL-STD-704A with 50 ms holdup (power supply); MIL-STD-461F & MIL-STD-810G.
