El TX326 es un transmisor satélite que utiliza el sistema de satélites Meteosat para proporcionar comunicaciones unidireccionales desde una plataforma de recolección de datos (DCP) a una estación receptora.
Meteosat es un sistema de satélites meteorológicos geoestacionarios operados por EUMETSAT (Organización Europea para la Explotación de Satélites Meteorológicos). Los satélites geoestacionarios tienen órbitas que coinciden con la rotación de la Tierra, lo que permite que cada satélite permanezca por encima de una región específica. EUMETSAT es una organización intergubernamental creada a través de una convención internacional de países europeos.
Leer másThe 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:

GRANITE-series, CR6, CR1000X, or CR300-series data logger program for the TX326 and TX325 that sets up self-timed and random transmissions and reads diagnostic information. Another program is available for the TX325 with the CR3000, CR1000, or CR800-series data loggers because they are programmed differently.
