Key Features

  • Operational life is extended by a factor of three 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 a unit "on" or "off". When turned "off", this model consumes about 8 μA. Given this low quiescent current level, users can store their units for extended periods with minimal impact on operational life.

Operational Life Information

Operational life

This graph provides a means to evaluate the total number of 4-byte Argos messages that can be transmitted (or "uplinked") by the A-3610 given a specified operational lifetime. Both low power and high power operational life predictions are shown for comparison. The transmissions can be scheduled as per user requirements using the A-3610 scheduler. The repetition rate, daily and seasonal duty cycles can be modified as required to meet study design. Modifications of these operational parameters can be made at the factory or by the researcher using the Telonics Product Programmer (TPP).

Operational life

This graph is related to the first one above. The graph provides a means to evaluate the total number of hours a 4-byte Argos message can be transmitted (or "uplinked") by the A-3610 given a specified operational lifetime. Both low power and high power options are shown for comparison. The hours of transmission can be scheduled as per user requirements. The Argos repetition period used to generate this graph is 60 seconds. Daily and seasonal duty cycles can be modified as required to meet study design. Modifications of these operational parameters can be made at the factory or by the researcher using the Telonics Product Programmer (TPP).

Programmable Features

The A-3610 can be fully programmed at Telonics per the user's instructions so it arrives ready for deployment. Alternatively, researchers can choose to construct the data collection scheme and transmission parameters at their laboratory. Field programming the A-3610 can be done at any time prior to deployment.

TPP, the Telonics Product Programmer, is a software utility that allows the user to customize and program the unit's role and mission. The TPP demonstration software allows researchers to evaluate programming functions and data collection capabilities for all supported transmitter models for 30 days. The demonstration version of TPP is fully functional with the exception that it does not support actual programming of hardware. Users can purchase the "software key" to convert their demo version into a fully operational program.

Programmable Transmission Parameters

  • ID code: Any valid 20-bit or 28-bit Argos ID code
  • Repetition period: 5 to 3600 seconds, as authorized by Argos
  • Seasons: Up to 32 intervals of time (1 day to 100 years, in 1 day increments) in which on periods occur
  • Frequency: 401.618 MHz to 401.680 MHz, as authorized by Argos
  • Transmission power level of 500 mw

Sensors and Data Collection Programming

Saltwater Switch (SWS) The SWS functions to:

  • determine when the unit (animal) is diving by establishing a qualified dive and suppress transmissions during the duration of the dive. A qualified dive occurs after the duration of the dive exceeds a user-determined time period (usually a few seconds). The qualification period distinguishes between "splashes" and "real" dives.
  • calculate dive information during a user-specified time interval. The information can include the number of dives, maximum dive time, average dive time, and/or total time underwater during the sampling interval.
  • provide individual dive durations.
  • determine a "haul-out" condition and shut down Argos uplink transmissions after a user-determined time interval has elapsed to conserve battery life.

Temperature Sensor: Measures temperature between -40 to +70°C, ±1°C accuracy.

Low Voltage Sensor: Determines the battery condition by measuring the battery voltage during transmission.

Activity Sensor: Determines animal activity level based on animal movement measured within a specified interval.

Mortality Sensor: Infers whether or not the animal is dead by comparing the animal activity level to a specified threshold.
