NanoTag Series Coded Radio Transmitters

Introducing the smallest coded radio transmitter in the world: 1/4 gram NTQ

LOTEK NanoTag Series transmitters furnish researchers with a tool to collect previously unavailable data regarding movement of animals in their natural environment.

The NanoTag Series’ field-proven, energy efficient design delivers a highly stable signal, while its diminutive size and relatively long operational life enable biologists to collect data on smaller species over longer periods than ever before.

 

• Infrared activation and deactivation: no magnet required
• Frequency Tolerance - to <100Hz: stable operation throughout tag life
• Supports activation programming: extends transmitter's operational life
• Digitally encoded transmission: multiple detections on a single frequency

At the heart of the NanoTag-series transmitter is a technological breakthrough in micro-circuitry design. NanoTag brings three distinct technologies, radio, digital processing and infrared, together on a single 2.8mm² ASIC (Application Specific Integrated Circuit) to meet requirements long sought within the fisheries research field. A very small, highly stable and field proven radio transmitter with a long operational life relative to its size is now available.

NanoTag series radio transmitters are primarily designed for use with LOTEK digitally encoded systems. Based upon a proprietary coding scheme, our coded telemetry systems allow over 500 transmitters to be assigned on a single frequency, while retaining the ability to identify individual animals. This capability significantly reduces the need for additional frequencies over conventional pulsed or beeper systems, with a corresponding reduction in overall scan time. Spatial and temporal resolution are enhanced accordingly.

Burst rate/intervals selected for the NanoTag transmitter can be specified in 0.1 second increments to best meet application and operational life needs, as well as be programmed for diurnal operation.
