Overview

TX326 Satellite Transmitter for METOSAT (-40 to +60C)

The TX326 is a satellite transmitter that uses the Meteosat satellite system to provide one-way communications from a data collection platform (DCP) to a receiving station.

Meteosat is a system of geostationary meteorological satellites operated by EUMETSAT (European Organisation for the Exploitation of Meteorological Satellites). Geostationary satellites have orbits that coincide with the Earth's rotation, allowing each satellite to remain above a specific region. EUMETSAT is an intergovernmental organization created through an international convention of European countries.

Key Advantages

New Standard for Reliability in Meteosat Transmitters

Technical Description

The TX326 transmitter uses the Meteosat satellite system to provide one-way communications from a data collection platform (DCP) to a receiving station. Supported transmission rates are 100 (SRDCP) and 1200 (HRDCP) bps. This transmitter is used with our CR300, CR310, CR1000X, and CR6 dataloggers, as well as with our GRANITE measurement and control data-acquisition systems.

Because clock accuracy is critically important for Meteosat satellite telemetry, the TX326 includes an embedded GPS receiver. The GPS receiver automatically corrects for clock and oscillator drift, allowing for longer intervals between service visits.

Detailed diagnostic information about the radio is also available for the field technician and various diagnostic uses. These diagnostic parameters include the following:

Latitude and longitude using the built-in GPS
Current battery voltage
Current temperature
Battery voltage before last transmission
Temperature before last transmission
Battery voltage during last transmission
Altitude of last GPS position
Time of last GPS position
Number of GPS fix misses
Time of last missed GPS fix
GPS receiver health and status
Failsafe tripped indication
Duration of last transmission
Forward power of last transmission
Reflect power on last transmission
VSWR (voltage standing wave ratio) last transmission results
Current transmission state

Cable Options

On the Ordering Information page of the website, ensure you order the correct cable option to meet your needs.

To connect the TX326 to the CR6 or CR1000X RS-232/CPI port. select the -R option.
