SeaTag™ Marine Mammals Tracking System

The Technology

SeaTag™ is a solar-powered marine technology that offers low-cost, reusable, and modular tags for tracking sea mammals in both salt and freshwater environments.

The satellite-based tagging technology uses battery-augmented solar power and is built to withstand harsh environments.

Desert Star‘s full suite of available SeaTags™ products are equipped with:

  • An accelerometer (measures activity of animal)
  • Light sensors (allows for longitudinal locating via amount of daylight)
  • Magnetic sensor (allows for latitudinal locating)
  • Temperature sensor
  • Depth sensors

SeaTags™ communicate globally with product users through the use of the Argos satellite constellation.

After a programmed amount of time, the sensor detaches from the animal subject and floats to the surface, where it can be collected and reused.
