ILS receivers are dual-channel avionics units that process VHF localiser signals (108–112 MHz) and UHF glideslope signals (329–335 MHz) simultaneously, providing lateral and vertical deviation outputs to flight director and autopilot systems. Manufacturing covers RF front-end assemblies, DSP-based signal processing, ARINC 429 data bus integration, and DO-160/DO-178C-qualified firmware development.
