Key Features
- The TAV-2627 is an Argos Transmitter (no GPS receiver).
- 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 are battery powered and 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-26 based units consume less than 5.3µA. Given this low
current level, users can store their units for extended periods with minimal impact on
operational life.
- Data Decoding - Data are processed using the Telonics
Data Converter (TDC), which provides complete data decoding of Argos DS files and supports
complete memory downloading. TDC provides a comma separated value (csv) output file with time
stamps for all data collected. TDC can also be run in the "batch mode" for hands off
operation.
- TDC allows you to plot Argos locations
with Google Earth.

1. Reduced power modules offer an increase in operational life of approximately 30%. Contact the
lab for more information.
2. 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.

Note 1: At +70°C, transmit current will increase by approximately 10% from the
+25° C measurement. Conversely, at -40° C it will decrease by approximately 10%
from the +25° C measurement.
Note 2: Transmit current and RF power out are sensitive to VSWR. Both can be degraded
significantly if the antenna or antenna coax are of poor quality or not correctly tuned
and matched to the ARGOS/Brazilian frequency band 50 ohm RF output impedance.

| TAV-26xx Packing/Housing Specifications: |
Designed for application on most birds. Units are enclosed in a hermetically sealed canister. The Argos antenna assembly employs a strain-relief to avoid breakage.

Service Commitment
Since 1970, Telonics has built a reputation based on product quality, product support, service,
and customer satisfaction. Telonics strives to produce the highest quality products, and to
support those products accordingly.
Because of extreme conditions and the unpredictable nature associated with most telemetry
applications, problems occasionally arise. Most problems can be resolved quickly. In all cases,
we hope to be able to work in partnership with users to resolve problems to the user's
satisfaction and to uphold our demonstrated commitment to excellence. If problems should arise,
all products must be returned to our factory for failure analysis.
