RadioTag-14 is world's most advanced telemetry logger with radio download.
Total device weight: 10g

High quality data for your project

This logger stores (and later transmits) records with following content:

  1. Geographical coordinates (GPS)
  2. Speed (GPS)
  3. Altitude (GPS)
  4. Pressure: both barometric (air pressure) and hydrostatic(under water)
  5. Acceleration
    1. X axis
    2. Y axis
    3. Z axis
  6. Angular speed (speed of rotational motion) - measured using gyroscope
    1. X axis
    2. Y axis
    3. Z axis
  7. Terrestrial magnetism - measured using magnetometer (gives information about animal absolute orientation)
    1. X axis
    2. Y axis
    3. Z axis
  8. Temperature
  9. Voltage on the solar panel, what gives rough estimate about light intensity

You get high quality datapoints from GPS, not like from legacy VHF telemetry.

How it works

System consists of two types of devices:
  1. Logger (tag) - you attach it to the animal under study. Usually there are many loggers in given project.
    • Logger captures and stores records in it's internal memory.
    • When logger gets into downloading range of the base station, records are sent to the base station. It is not required to stay within the downloading range all the time: You can download data from animal after months, when it comes back to the downloading range. It's quite common to download data from birds after they are back from migration.
    • Later you retrieve records from base station to your computer.
  2. Base Station - it automatically downloads data from loggers (via radio) and stores it in internal memory.
    • Base Station can be easily carried by human or placed in the field for longer time (days/months). Some customers lift base stations with drones/aeroplanes/helicopters.
    • Single base station can handle up to 100 loggers at given time.

Get more out of your devices: powerful energy saving features

  • Geofencing – you can set up to 2 zones with custom registration intervals. This is very helpful when you want to perform higher frequency GPS registration in areas of your interest. Conversely, you can also use this feature to have lower record interval in areas which are not that interesting for you (in order to conserve the energy to register more data from areas that matter).
  • Custom registration intervals in selected hours – Imagine that your species sleeps at night (quite common scenario) and is active during the day. With this feature you can set for example to register only 1 position per hour during the night (to be sure that animal stayed at the same place during night) and 5-minute interval during the day (to normally register daily activity). This feature is also very useful if you know that your animal is highly active during selected hours (e.g. 2 hours at dawn and 2 hours at dusk). If that’s the case, you can set higher registration interval during those periods.

Capture the dynamics: burst collection capabilities

Sometimes you need to capture high-frequency bursts of data. For example:
  • when analyzing animal's energy expenditure from its acceleration
  • when studying diving dynamics (e.g. how fast diving animal reached particular depth and how much time stayed there)
  • when classifying types of behavior

RadioTag-14 allows you to capture high-frequency bursts from accelerometer and gyroscope:

  • Accelerometer (X,Y,Z): 1 Hz, 10 Hz, 50 Hz, 100 Hz
  • Gyroscope (X,Y,Z): 1 Hz, 10 Hz, 50 Hz, 100 Hz

During collecting high frequency burst from accelerometer / gyroscope, you can also collect additional information with 1Hz frequency (1 record per second). Those additional records may include:

  • Pressure
  • Temperature
  • Magnetometer (X,Y,Z)

Of course, you can choose to collect all above data in a single burst. For example, it's entirely possible to collect burst with following contents: all axes from accelerometer collected with frequency of 50 Hz, all axes from gyroscope collected with 50 Hz, temperature collected with 1 Hz, pressure collected with 1 Hz, all axes from magnetometer collected with frequency of 1 Hz.

Burst duration (how much time one burst takes) and interval (how much time between bursts) are user-configurable.
