Abstract: The subject matter disclosed herein relates to systems, methods, apparatuses, articles, and means for determining at least one navigational coordinate system to be utilized in conjunction with transports and/or mobile devices. For certain example implementations, a method by a mobile device that is at least proximate to a transport may comprise identifying a first navigational coordinate system, with the first navigational coordinate system being associated with the transport and enabling navigation within at least one navigable area of the transport. A second navigational coordinate system may also be identified. The mobile device may determine to utilize at least one of the first navigational coordinate system or the second navigational coordinate system based, at least in part, on one or more predetermined conditions. Other example implementations are described herein.
