Commonality in Disparate Trajectory Predictors for Air Traffic Management Applications

Quantification of aircraft trajectory prediction uncertainty using polynomial chaos expansions

“…Despite the fact that not all Trajectory Predictors (TP) are designed and implemented similarly and do not make use of the same data sources, for ATM interoperability purposes, the FAA/EUROCONTROL Action Plan 16 proposed a generic TP model , including a set of common architectural concepts upon which TBO capabilities could be developed [7]. The core of the models is the Trajectory Prediction Process (TPP), which encompasses the process of obtaining a computed trajectory (CT) by means of a set of methods and algorithms implemented by the Trajectory Computation Engine (TCE).…”

Applications of Formal Languages to Management of Manned and Unmanned Aircraft

“…This decomposition is more fine-grained than previous trajectory prediction structures [16,38,45,147], although it is compatible with such structures.…”

“…It is an evolution from previous works presented in [38,45] and [16,147]. The main improvements of this new architecture are the more granular division of components and the use of formal languages to share information among these components.…”

“…The common trajectory predictor structure shown in figure 3.1 was developed by the FAA/EUROCONTROL Action Plan 16 [45]. This structure is the result of identifying common aspects among trajectory predictors, combined into a single logical structure.…”

“…In an attempt to improve interoperability among different trajectory predictors, the processes common to any trajectory predictor were identified in [38,45]. Among these elements is the trajectory engine, which computes a trajectory from some unambiguous description of the aircraft's behaviour, denoted flight script or behaviour model.…”
