Product Overview
The ILS-3M Instrument Landing Simulator is a highly integrated, portable instrument designed for in-situ qualitative testing of onboard instrument landing systems. It provides status confirmation for instrument landing receivers installed on aircraft parked on the tarmac. The simulator generates radio frequency signals covering the full frequency band with varying modulation depth differences, simulating ground-based localizer and glide slope signals. It also simulates marker beacon signals (far, middle, and near) through a dedicated antenna, transmitting localizer, glide slope, and marker beacon radio waves to verify the proper functioning of the onboard instrument landing system.
