LEGO with three elevated solar panel(backpack)

LEGO – neck collar


LEGO, our flagship device is a solar-powered GPS-2G/3G-ACC tracker suitable for backpack deployment for birds weighing 600 grams and more.

Now also available in 4G and 5G version.

The enclosure of Debut® Lego is specially designed based on aerodynamic modeling to minimize the possible impacts on the flying behaviors.

Being full-featured and compact-sized, Debut® Lego has been used on species of various sizes, as either a backpack or a leg band. Two sets of threading-holes are optional to suit different body shapes. Debut® Lego had accompanied, and witnessed, a demoiselle crane flying over Himalaya mountains for wintering and then back to Kazakhstan to complete a migration cycle.

Going with different stands, the original Debut® Lego can be elevated to another three heights (26.5 mm, 40.5 mm, and 50.5 mm) to suit birds with different feather thickness.

GPRS ( 2G data ) I GSM ( 2G SMS ) I 3G
Data Collection & Transmission Setting:
Regular-Interval Mode:
- GPS interval: 5 min ~1 day
- ENV interval: 5 min ~1 day
- ODBA interval: 10 min/30 min
- ACC interval: 25 Hz, 3 seconds in every 10 min (by default)
- Transmission interval: 5 min ~1 day
Above ranges are selectable on website data platform or App. Contact us if other settings are required.
On-Time Mode
- Transmission: Up to three times at fixed hours per day (such as 13:00/14:00/18:00)
- GPS / ENV / BHV: Regular-interval model or on-time model follow each transmission
Sleep Mode
This mode is to deactivate certain type of data collection for:
- a certain period (from minutes to months)
- a regular period each day (a maximum of 16 hours)
Intelligent Frequency Optimization & Flight Detection (BOOST)
The BOOST function intelligently increases data collection & transmission frequency when the charging condition is good or the bird is flying. The default setting is as below:
Frequency Optimization:Every 10 min/1 min
Flight Detection:Every 20 sec
With BOOST, the device portrays detailed movement tracks without manual intervention and avoids the possibility of battery drain due to radical settings in bad weather.
Data Storage
Logged data will be stored in memory if network is unavailable.
Flash memory:16 MB
Regular data storage:460 days at default setting (1h GPS+1h ENV+10 min BHV)
