A proposal for collaborative navigation in corridors

The current study presents the proposal of a collaborative method to take advantage of the available information from surrounding airplanes in a corridor and provide a back-up navigation aid with a performance equivalent to GPS. Here it is considered that an aircraft may use the information of distance between itself and other airplanes provided by TCAS as well as the absolute position information of aircraft made available by ADS-B, creating a dynamic constellation similar to GPS where the satellites are replaced by the surrounding airplanes. A simulation study considering two types of traffic scenarios is developed to access the resulting accuracy of the proposed system
