The GLU-925 Multi-Mode Receiver includes three elements: high integrity GNSS receiver; Category IIIB certified ILS and Category I GLS approaches growth to CATII and CATIII landings.

The 24 channel GNSS receiver meets or exceeds all applicable industry requirements and provides position, velocity and time (PVT) outputs for use by other aircraft systems such as TAWS and FMS. The ILS function included in the GLU-925 is functionally equivalent to standalone ILS like the ILS-900 and GLU-920.
