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.
DAQ systems are typically comprised of a chassis, backplane controller and customer-selected modules. Embedded DAQ systems have the ability to combine the I/O subsystem and mission computer into one package. Communications-based DAQs interface with a computer through a communications port and can act as remote, intelligent control systems. Serial communications such as RS-232 and RS-485 provide the ability to communicate long distances with multiple units on the line.
Additionally, these rugged systems must meet stringent environmental requirements such as shock, vibration and extreme temperatures within SWaP-constrained environments. These attributes are inherent in most COTS designs and offer customers readily-available, interoperable, field-proven systems and subsystems out of the box.
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.
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. Rugged systems used in carrying out high-performance, defense missions must meet stringent environmental requirements such as shock, vibration and extreme temperatures within SWaP-constrained environments. These attributes are inherent in COTS designs and offer customers readily available, adaptable, field-proven systems and subsystems.

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.

Military vehicles must have the ability to meet evolving combat requirements while operating under hostile conditions and the reliability to function effectively under such conditions. 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.
The technology of IVHM enables the collection of information on an object's status, condition, and performance. It also facilitates the transmission of this information, often from hostile environments. By linking fault sensors and other sources of data that monitor component, systems and subsystems, early warning maintenance costs, and improve vehicle readiness. By identifying potential faults and failures, the proper corrective action can be taken. Primarily, such decisions will enable the maintainer to better schedule maintenance based on actual performance and condition of an asset (the airplane itself, or any of its parts) rather than when a component fails or when regular maintenance cycle is performed. Any event that leads to a plane malfunction in between these two parameters can be flagged and addressed by consistently applying IVHM.
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 Vehicle Health Monitoring systems provide the foundation for identifying potential faults and failures, indicating the need for corrective action either when a component fails or when regular maintenance cycles are required.

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. These rugged, high speed, modular A/D, D/A conversion devices are designed primarily for specific avionics systems including fixed-wing, rotorcraft and unmanned aerial vehicle (UAV) platforms.
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.
