The present invention relates to a distributed architecture for all aerial navigation aids. So that this architecture makes it possible to reduce the weight and/or the bulk of the cables linking the antennas to the corresponding equipment, as well as the weight and/or the bulk of at least part of said equipment, a part at least of the receivers is sited remotely in proximity to the corresponding antennas, and a part at least of the power supply for the equipment of the aircraft is centralized, and this centralized supply distributes a stabilized DC power supply to the remotely sited equipment.
