Performance Comparison of Argos and Iridium Tracking Technologies for Sea Turtle Movement Ecology Studies.

ABSTRACT: Satellite tracking has dramatically improved research on wide-ranging large marine vertebrates such as sea turtles. Traditionally, sea turtle tracking has relied on Argos-based satellite telemetry tags, which estimate location via Doppler shift and can also transmit sensor data. GPS-equipped Argos satellite tags represented a significant evolution, offering higher location accuracy. More recently, GPS-equipped satellite tags transmitting via the Iridium satellite network have become available for sea turtle tracking, and this study aims to assess whether they offer additional advantages. The performance of three satellite tag types-Argos-only, Argos-GPS, and Iridium-GPS (Iridium)-was assessed using data on 116,074 positions from 48 sea turtles representing five species and multiple ocean b
