Introduction

Telonics is pleased to introduce the next generation of Argos Avian Transmitters. Telonics has pioneered the development of animal-born Argos transmitters beginning with the first successful deployments of Argos units on large mammals in the early 1980s. Since those early experiments, we have been involved in the instrumentation and study of literally thousands of free ranging animals worldwide. With the certification of the ST-24 Argos transmitter in early 2003, the door has opened to a new generation of microminiaturized Argos systems well suited for deployment on a variety of bird species.

Key Features

Operational life is extended relative to older transmitter models, due to ultra-low quiescent current and highly efficient radio transmission circuitry.
Real-time clock calendar (RTC) controls all timing functions.
Powerful data collection and transfer capabilities allow the units to acquire, queue, and transmit temperature and activity information.
User programmability allows researchers to reprogram units in the field and change their role and mission.
- On-board sensors can be activated or deactivated in the field. Data collection regimes and schedules can be altered as required. Sensor data can be enhanced or deleted from Argos uplink transmissions.
- Transmission schedules can be modified.
- Argos ID codes can be changed.
- Argos uplink transmission power levels can be modified to extend operational life or increase the probability of signal reception at the satellite.
- Argos uplink frequencies can be changed to frequencies in low noise channels to increase the chances of a successful uplink.
Units can be refurbished to their original condition at the factory.
Shutdown with a small magnet allows users to turn each of these configurations "on" or "off". When turned "off", ST-24 based units consume less than 4 μA. Given this low current level, users can store their units for extended periods with minimal impact on operational life.

1. Operational life expectancy is based on a continuous series of transmissions of a 4-byte Argos message at a 60-second repetition rate at 25°C.
