Argos Marine Transmitters (TAM)
Argos only, without GPS

TAM Units
Five fully configured models designed specifically for marine applications are shown. Tubing provides strain relief and mechanical protection for the antenna assembly.

Key Features

  • The TAM-26xx series provides a small, light weight package for smaller species or juveniles. Data such as last dive time, dive count, maximum and average dive time, percentage of time spent under water and temperature can be transmitted.
  • The TAM-4xxx series utilizes a new hydrodynamic housing design. Data such as last dive time, dive count, maximum and average dive time, percentage of time spent under water and temperature can be transmitted. The TAM-4xxx series can also be configured with a pressure transducer. Depth of a dive, profile of a single dive and percentage of time in user defined depth layers are available. In addition to transmitting the data, they are also stored on board the unit in non-volatile memory. The TAM-4xxx series supports a highly compressed data transmission called page data. This series of units also support a VHF Tracking Beacon incorportated inside the housing. The VHF transmitter shares the transmitting antenna with the Argos transmitter.
  • A micro-power saltwater switch (SWS) saves additional power and further extends the operational life of the unit.
    The SWS is critical to successful performance of an Argos marine unit. Because radio frequencies are severely attenuated in salt water, any uplink transmissions while underwater are essentially wasted. The SWS functions to suppress transmissions while the unit is submerged thereby saving power. The SWS synchronizes uplink transmissions to resume at the precise time when a marine animal actually breaks the sea surface following a dive. By transmitting immediately upon resurfacing, the unit has the best chance of successfully getting uplink transmissions to available orbiting NOAA satellites. Further, the SWS can be used to determine a haul-out condition and shut down Argos transmissions during extended shore time to save additional energy.
  • Real-time clock calendar (RTC) controls all timing functions.
  • 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.
  • Powerful data collection and transfer capabilities allow the units to acquire, queue, and transmit temperatures and dive information.
  • 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.
  • Shutdown with a small magnet allows users to turn each of these configurations "on" or "off". When turned "off", TAM-26xx series based units consume less than 5.3 µA, and TAM-4xxx series based units consume less than 12 µA. Given these low current levels, users can store their units for extended periods with minimal impact on operational life.
  • Units can be refurbished to their original condition at the factory.
