Availability and accuracy estimation of air transport alternative positioning for Lithuanian airspace

Abstract

Alternative positioning and navigation play a significant role in air transport system of the region. The most important characteristics of airspace such as availability of alternative positioning method and accuracy of positioning have been estimated for Lithuanian airspace. Alternative positioning algorithm by distance measurement equipment and optimal pair of waypoints was considered. Obtained contour graphs and results are quit important to guarantee integrity, continuity, availability of air navigation services and as a result to monitor safety of air transport in limited volume of airspace.
