This article shows the effects of various parameters like modulation or the radio channel conditions on sea turtles trajectory estimated by terrestrial localization algorithms. This work is part of wireless sensors networks domain in the marine and terrestrial environment in the world of living beings. It allows to identify and understand the parameters that lead to inaccuracies over the sea turtles trajectory. Another important part of this project is to have a better understand about the morphology of the sea turtles and his environment. It also proposes another way to localize sea turtles.
