TGE-100 GPS-Argos/ST-14

The information below on discontinued products is provided for individuals who are still using these older systems. Product descriptions may be time sensitive or even outdated. Please contact Telonics if you have questions.

The TGE-100 GPS/ARGOS/ST-14 unit has been designed for oceanographic, meteorological, and climatological studies. The unit is based on the Generation II microGPSI controller, which integrates the Trimble Lassen SK8 GPS receiver and ST-14 RF Module (Argos PTT) in a small versatile configuration. The unit utilizes the Telonics TO2 Format for transmitting from 1-7 C/A code GPS positions in a single Argos 32 byte message.

The ST-14 is a 1.0 watt Certified Argos PTT RF Module. The system supports an option that can also store positions in the microGPSI nonvolatile memory in a form that allows for post processing differential correction (DGPS) of the stored positions upon recovery of the unit. DGPS positional information is not transmitted in the Argos message due to the limitations of the message length. The unit has a serial interface that allows the users to modify all user changeable parameters through the use of a Windows® based Parameter Configuration Utility (PCU) or recover data stored for differential correction using Telonics Differential Correction Utility (DCU-1). Actual differential correction requires Trimble Pathfinder Office.

The units are available for operation in the standard oceanography temperature range -10° to +50° C and in the extended temperature range of -40° to +70° C. The TGE-100 can be procured with various housing packages including a fully hermetic package designed for the most rigorous environments. Other options are available upon request. Please consult the factory for further information.
