The development of a positioning approach based on miniaturized GNSS receivers for measuring flight trajectories with decimeter precision is the first of the two central objectives of the work. This development realizes high relative precision while overcoming the need for a second nearby base receiver or any (static) initialization patterns. This is achieved by designing a novel relative positioning method based on time-differences of L1 carrier phase observations.
This methodology is the basis for the realization of the second central objective: the first-time measurement of flight trajectories of Wandering Albatrosses in the Southern Indian Ocean with a precision and resolution sufficient for analyzing the dynamic soaring flight of the birds from a flight mechanical perspective. With the in-depth energetic and dynamic investigation of individual flight cycles a contribution is made to a better understanding of this highly energy efficient flight method.     «
