The CNS/ATM concept envisages reliance on global satellite navigation systems to underpin future air traffic management that is able to cope with the ever-increasing demand for air travel without jeopardising safety and the environment. Implications for technology design and integration are provided. Execution errors were best mitigated by the HUD, which disambiguated the environment and depicted the clear ed taxi route. Decision errors were mitigated by technologies that provided both local and global awareness including information about the distance to and direction of the next turn, current township location, and a graphical depiction of the route (as provided by the EMM and HUD together ). Planning errors were mitigated by technologies that provided an unambiguous record of the clearance (datalink and the EMM, which possessed a text-based clearance). Each error class was associated with a unique set of contributing factor s and mitigating solutions. Pilots committed navigation error s on 17% of current-day operations trials (in low-visibility and night), distributed roughly equally across the 3 error classes. This taxonomy was applied to error data from 2 full-mission simulation studies (Hooey, Foyle, Andre, & Parke, 2000 McCann et al., 1998) that included trials that replicated current-day operations and trials with advanced cockpit technologies including datalink, electronic moving maps (EMM), and head-up displays (HUDs). We show the necessity of this statistical component for realistic prediction purposes in comparison to pure deterministic predictions by means of simulations on a test-case.Ī taxonomy of navigation errors (pilot deviations) during taxi operations was developed that defines 3 classes of errors: planning, decision, and execution errors. For a particular scene its outputs are the statistical moments of the GPS range error. Its statistical origin is the variability of the environment.

This hybrid simulator is based on the deterministic simulator via Monte-Carlo simulations. To account for the limits of these choices, we define in this paper a new statistical model and we propose an innovative hybrid deterministic-statistical GPS multipath simulator adapted to airport navigation.
They concern both the electromagnetic method and the precision of the data used to describe the 3D scene.
Regarding the design of this deterministic model, we have carefully justified the choices we have made to obtain reasonable computation times. In previous papers we have presented a GPS multipath simulator based on physical optics.

The paper will therefore introduce the concept of private graphs, which is defined as a graph for navigational purposes covering the street, road or floor network of an area behind a public street and suggest different approaches how to make graph data for navigational purposes available considering access rights and data protection, privacy and security issues as well.Ī prediction model of GPS multipath requires a constant trade-off between computation time and realistic modeling. The analysis of case studies will show, that the objective of navigation and the different target groups for navigation solutions will demand well defined access rights and require solutions, how to make only parts of a graph to a user or application available to solve a navigational task. In contrast to navigation and routing services on public streets, seamless navigation will cause an additional challenge: how to make routing data accessible to defined users or restrict access rights for defined areas or only to parts of the graph to a defined user group? The paper will present case studies and data from literature, where seamless and especially indoor navigation solutions are presented (hospitals, industrial complexes, building sites), but the problem of restricted access rights was only touched from a real world, but not a technical perspective. After the success of GNSS (Global Navigational Satellite Systems) and navigation services for public streets, indoor seems to be the next big development in navigational services, relying on RTLS – Real Time Locating Services (e.g.
