Adaptive Tracking Tags

These are a new generation of wireless ultra-low power tracking devices for monitoring animals (amongst other things) that feature:

  • Multiple supported sensor streams using a consistent API
    • 3-D acceleration
    • 3-D compass
    • Light level
    • Temperature
    • Magnetic field strength (used for Magneto-Inductive positioning)
    • GPS
    • Proximity to other animals
  • Lightweight, dictionary free, compression algorithm
  • Adaptive sensor sampling
  • Robust and reliable wireless data transfer
  • Continuous monitoring (3-6 months at 8-16 Hz sampling rates)

These have been used on a number of species (lions, badgers, swans, hares, eagles) to obtain data on a scale and scope previously impossible. Below is a picture showing a lion equipped with one of our wireless accelerometer devices, which runs for 6 months, collecting over 700 million samples per animal.
