| This paper deals with the modeling of the over sea radio channel and aims to establish sea turtles localization off the coast of Reunion Island, and also on Europa Island in the Mozambique Channel. In order to model this radio channel, a framework measurement protocol is proposed. The over sea measured channel is integrated to the localization algorithm to estimate the turtle trajectory based on Power of Arrival (PoA) technique compared to GPS localization. Moreover, cross correlation tool is used to characterize the over sea propagation channel. First measurement of the radio channel on the Reunion Island coast combine to the POA algorithm show an error of 18 m for 45% of the approximated points |

| 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. |

| This paper deals with the modeling of over sea radio channel with the aim of establishing sea turtle localization off the coast of Reunion Island but also on Europa Island in the Mozambique Channel. In order to model this radio channel, we are making a measurement protocol. In a first approach, measurements of turtle trajectory were done over land and finally it will be conducted over sea. We have scheduled an over sea measurement campaign in the middle of June. This paper shows a signal cross correlation technique used to characterize the over sea propagation channel. |
