hi,
what does the multi- mode receiver actually do? any reference would be apreciated. thanx |
It is the ILS Localiser and Glide Slope receiver combined with the GPS receiver.

AMM 34-36-00 if you don't have access, only the first General paragraph.
G__e_n_e_r_a_l The primary function of the Multi-Mode Receiver (MMR) is to receive and process Instrument Landing System (ILS) and Global Positioning System (GPS) signals. The MMR is a navigation sensor with two internal receivers. A. ILS Receiver The function of the ILS is to provide the crew and airborne system users with lateral (LOC) and vertical (G/S) deviation signals, with respect to the approach ILS radio beam transmitted by a ground station. The localizer operates in a frequency band which ranges from 108.1 MHz to 111.95 MHz and the glide uses the band from 329.15 MHz to 335 MHz as defined by ARINC specification 710. B. GPS Receiver The GPS is a radio aid to worldwide navigation which provides: - the crew with a readout of accurate navigation information, e.g. position, track and speed - the Flight Management, Guidance and Envelope Computer (FMGEC) with position information, after hybridization in the Air Data/Inertial Reference Unit (ADIRU) with inertial parameters, for accurate position fixing. |
