LEG RINGS
Target species:
– storks,
– cranes,
– spoonbills,
– flamingos, etc. …. The ring size could be customized
LEG RINGS are leg-mount GPS-ACC-GSM devices designed for long legged birds to be attached on tibia using a special oval shaped ring with a snap-fit design, allowing you to secure the ring to bird leg by one single press.
Special oval shape of LEG model makes the ring not rotate on the bird’s leg. Thanks to this, the solar panels is always placed at the front to minimize covering by the body of the bird. Charging is very efficient and works even when the sun’s arays do not fall directly on the solar panels.
| LEG RINGS - GENERAL SPECIFICATION | |
|---|---|
| Appearance & Measurement | |
| Weight: | From 19g |
| Antenna: | Internal |
| Housing: | Strong and water proof. Various colours are possible. |
| Data Types | |
| GPS: | Longitude, latitude, altitude, geoid height, course, satellite quantity |
| ENV: | Voltage, light intensity, temperature |
| BHV: | ODBA (overall dynamic body acceleration) |
| ACC: | x/y/z acceleration data (upon request) |
| BSS: | longitude, latitude, altitude (alternative locating method for extreme situation) |
| Power Supply | |
| Solar type: | GaAs solar unit (30% efficiency) with good performance under weak light |
| Battery type: | Lithium polymer rechargeable battery with under-and-over-charge protection |
| Battery capacity: | from 30mAh to 230mAh |
| GPS Module | |
| GPS precision: | CEP (50%) 5m |
| Max update rate: | 10 Hz |
| Transmission Module | |
| GPRS (2G data) | GMS (2G SMS) BLE (Bluetooth Low Energy) |
|
| Transmission Rate: | 2G: Max. 85.6 Kbps/85.6 Kbps (uplink/downlink) |
| 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) |
| BOOST data storage: | 280,000 pieces |
| ACC data storage: | 28,700 pieces |
| Operational Environment | |
| Working temperature: | -20°C~60°C |
| Waterproof: | IP 68 |
| Firmware Upgrade | |
| Over the air (OTA) |
