SeaTag-MOD
Modular solar-powered tag with magnetometer, accelerometer and precision pressure sensor options, design tested to 2000m.
Description
SeaTag-MOD is a modular tag powered by stored solar power with optional battery and release sections (ST-MR, ST-MRPS, ST-MRPL). Sensors include a three-axis precision magnetometer (15 nT resolution), the solar panel as light sensor, a temperature sensor, a precision calibrated clock, a three-axis accelerometer and pressure sensor options of 2000m max depth (0.15m resolution) or 500m max depth (0.04m resolution). Data is stored on a micro-SD card (2GB standard) and accessed through a USB-TTL serial connector end-cap. SeaTag-MOD units are also used in SonarPoint arrays for drifting mooring localization and depth/temperature logging. SeaTag satellite tags are designed for long-lasting, high sample size studies of marine animals such as penguins, tuna, whales and deep diving swordfish; Desert Star highlights solar power, reusability and earth magnetic field sensing to fix fish locations beyond the reach of GPS.
