Method and applications for height measurement and the combining of the user with a content of detecting elevation movement for personal navigation systems

摘要

A method and apparatus for estimating the height of a user with respect to the average are initially introduced into the sea. According to a few points of view, it is capable of the present invention, the height of both under free sky as well as in poor gps - signal environments, such as, for example, dense urban trench environments where gps - power by less available satellite and / or packaging error is influenced, to estimate. According to other aspects, the present invention utilizes data from a pressure sensor, in order to estimate height, either with or without the use of supporting gps - data. According to further aspects, estimated height connected with other types of coupling navigation data, in order to a user - context - detecting changes in respect of height to permit.
