Solar ULTRA Avian Tag.

ULTRA is tiny GPS-Solar-ACC tracker that uses either INTELINK to transmit data directly via Bluetooth to mobile phone or to autonomous long range Bluetooth gateway, or uses the 5G cell phone network to upload data directly to the cloud server.

Data upload ULTRA Intelink

Transmission method: INTELINK based on Bluetooth 5.0

Maximum uplink/downlink speed: 1 Mbps/1 Mbps

Output power: 8 dBm

Transmission distance: 80~120m with ordinary smart phone; up to 1200m with Debut series gateway products.

Data upload ULTRA 5G

ULTRA 5G supports both NB-IoT and LTE-M (or called eMTC) frequency bands. We will activate selected bands for devices to be used in different regions. 









17 mm x 12 mm x 8.5 mm

Working Temp



15 mAh lithium polymer rechargeable battery, with under-and-over-charging protection

Battery Life

Over 100 GPS positions under optimal GPS satellite view at 5-minute interval

Solar Type

GaAs solar unit (30% efficiency) with good performance under weak light

Antenna Material

Titanium alloy with protective coating


Two through holes at two ends, respectively for harness, or glued-on

GPS Module

Precision: CEP(50%)5m 

Maximum update rate: 10 Hz



Firmware Upgrade

Remotely via network, or instantly via INTELINK

Working Scheulde

Remotely via network, or instantly via INTELINK

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 minBHV)

-BOOST data storage: 280,000 pieces

-ACC data storage: 28,700 pieces



  • GPS: longitude, latitude, altitude, geoid height, course, GPS satellite quantity
  • ENV: light intensity, temperature, inner air pressure, voltage
  • BHV: ODBA (overall dynamic body acceleration)
  • ACC: x/y/z acceleration data at 25 Hz (by default)


User can choose from the following data collection modes, and specify the related parameters to suit the condition and objective of the study. 

Regular 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)
  • Above ranges can be set on webpage/App. If other settings are required, please contact us. 

Sleep Mode

This mode is to save power by deactivating certain type of data collection for:

  • a certain period (from minutes to months)
  • a regular period each day (a maximum of 16 hours)

Raw Acceleration Data Collecting

Raw x/y/z acceleration data could be very useful for behavioral research, especially whenthe data can be combined with timestamps, GPS, environmental data, and the bird’s activityrhythm. However, the raw data can seldom be obtained due to its large size.

With INTELINK, the user can not only download the raw data from memory, but also obtainreal-time raw acceleration data by connecting a mobile phone to ULTRA.



The BOOST function intelligently increases the frequency for data collection when certain conditions are met (good charging, fast movement, etc.). 

The default setting is as below: 

  • Frequency Optimization: GPS at every 10 minutes
  • Flight Detection: GPS at every 5 minutes

With BOOST, the device portrays detailed movement tracks and attempts more frequent data transmission without manual intervention, keeping long-term energy balance and avoiding the possibility of battery drain caused by radical settings during bad weather.
