GPS Marine Systems (TGM)

TGM-4410, TGM-4610 and TGM-4310
Three fully configured models designed specifically for marine applications are shown. Tubing provides strain relief and mechanical protection for the antenna assembly.

Our GPS/Argos marine units are a new generation of GPS products that offer many new features and performance upgrades. This new Gen 4 technology is built on our highly integrated uGPSi-20 electronics platform, which combines store on board, Argos, and VHF beacon functionalities into a single assembly to achieve a durable and highly shock resistant electronics subsystem.

Key Features

  • Utilizes a new hydrodynamic housing design.
  • Contain a GPS receiver to obtain high accuracy GPS positions when adequate surfacing time occurs. When surfacing characteristics prevent a standard GPS position from being obtained, the Quick Fix Pseudoranging (QFP) alternative provides GPS positions using a post processing technique on surface times as short as 5 seconds.
  • Data such as last dive time, dive count, maximum and average dive time, and percentage of time spent under water and temperature can be transmitted.
  • 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 can be acquired and transmitted.
  • On board satellite overpass predictions allow a highly efficient data transfer as units can be programmed to transmit only to specific satellites and only during times when the satellites are in view.
  • Up to 24 positions per day can be recovered through Argos by using the innovative paging date protocol.
  • In addition to transmitting the data via Argos, these systems also store all data on board the unit in non-volatile memory.
  • To increase data throughput the TGM-4xxx series supports a highly compressed data transmission called page data.
  • Real-time clock calendar (RTC) controls all timing functions and is recalibrated with GPS time to assure high accuracy event timing.
  • Lower current consumption provides an increase in operational life or an increase in performance during that same operational time frame.
  • A micro-power saltwater sensor (SWS) saves additional power and further extends the operational life of the unit.

  • Shutdown with a small magnet allows users to turn each of these configurations "on" or "off". When turned "off", TGM-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.
  • 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 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.
  • 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 GPS fixes and Argos locations with Google Earth.
