What does a satellite transmitter look like?
A satellite transmitter is a small oblong shape box with an antenna that comes out of one end. Transmitters come in a variety of colours and sizes. The pictures at right show two kinds of satellite transmitters: the first one is a Telonics ST-18, which transmits location information only. The second transmitter (below) is a Telonics ST-14, which transmits and records location and dive information such as dive depth, duration and profile. A third transmitter commonly used for sea turtle tracking (not shown) is a Sirtrack KiwiSat 101 which transmits location information. Visit the Sea Turtle Tagging section of seaturtle.org for more details.
