Key Features

  • The IMPTAV-2630 is an Argos Transmitter (no GPS receiver). The IMPTAV-2630 is designed to be implanted into the body cavity of birds with the antenna extending out of the bird.
  • 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.
  • All products can be programmed by Telonics Product Programmer (TPP) which uses a GUI interface. TPP makes it possible for users to program their own systems and simulate performance of the system prior to deployment.
    • On-board sensors can be activated or deactivated by the user. 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.
