Data Concentrator Units (DCU): Data Concentrator Units (DCU) systems often serve as the "central nervous system" for most land, air and sea platforms and host the utilities functions, eliminating several boxes and hundreds of pounds of cable. These Modular Open Systems Approach (MOSA) systems feature an industry leading density of several I/O, measurement, and communication functions. These DCU’s take advantage of NAI’s COSA Architecture, offering 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.
Remote Data Concentrators (RDC): 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
Aircraft Interface Computer (AIC): Aircraft Interface Units (AIU) systems serve as a focal point in tying a wide variety of aircraft interfaces together. These Nano Modular Open Systems Approach (MOSA) systems offer pre-integrated MIL-STD-1553, ARINC-429/575, CANBus and Discrete I/O interfaces and take advantage of NAI’s COSA Architecture: a flexible, adaptable, configurable, modular and expandable solution that offers an almost infinite number of configurations while eliminating hardware and software NRE redesign.
Actuator Interface Units (AIU): Actuator Interface Units (AIU) systems serve as a focal point in tying a wide variety of sensors together that indicate temperature, flow, level or pressure. 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.
Flight Control Computers (FCC): Flight Control Computers (FCC) systems are used to support several platform flight control systems including fixed-wing aircraft, rotary aircraft, eVTOL and rocket systems. These Modular Open Systems Approach (MOSA) systems feature different analog and digital input and a wide range of communication types including MIL-STD-1533, ARINC-429, RS-232/422/485 and CANBus A/B 2.0/CAN-FD/ARINC-825. NAI’s rugged FCC 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.
Mission Computers (MC): Mission Computers (MC) 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. These Modular Open Systems Approach (MOSA) systems feature different analog and digital input and a wide range of communication types including MIL-STD-1533, ARINC-429, RS-232/422/485 and CANBus A/B 2.0/CAN-FD/ARINC-825. NAI’s rugged FCC 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.
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 RIU 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.
