Hardware-in-the-Loop (HIL) Simulation

Cost, availability, and safety make testing aerospace and defense systems in real-world settings impractical. Hardware-in-the-loop (HIL) simulation can virtually test embedded technologies like single-board computers and electronic chassis.

NI Expertise Overview

Testing and repairing intelligence, surveillance, and reconnaissance (ISR) systems in aircrafts and commercial space transportation requires time and money. To meet demands, engineers use HIL simulation to replicate specific embedded system parts and test them virtually before running real-world diagnostics on the complete system. This helps maintain ISR reliability and meet time-to-market requirements without exhausting resources, even as systems grow more complex. NI offers flexible software and modular RF instruments that support a range of RF test applications, including signals intelligence, record and playback, software defined radio (SDR), and multiple input, multiple output (MIMO)/beamforming. With NI’s PXI RF test suite, engineers can achieve faster measurement speeds with R&D-grade accuracy. The flexibility of the PXI platform ensures engineers can use PXI modular RF instruments to meet application challenges.
