) SCIENTIFIC WHEN MEASUREMENTS MATTER Overview 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 Benefits and Features ) EUROSAT SRDCP and HRDCP certified ) Compatible with Meteosat satellite data collection system ) Easy integration with Campbell Scientific data loggers ) Field tested and proven track record of reliability 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. For comprehensive details, visit: www.campbellsci.eu/tx326 W R(REIE TX326 Satellite Transmitter for Meteosat New Standard for Reliability in Meteosat Transmitters 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. ) Embedded GPS receiver for stabilized internal time keeping and transmit frequency for long service intervals ) Low standby current consumption for battery-powered systems at remote DCP installation sites ) Quick assessment of radio health via monitoring of diagnostic data from the radio 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 Specifications Transmissions Supported Self-Timed (Scheduled) Alarm (Random) Data Format ASCIl data with restrictions Meteosat alert message Binary data ASCll data Pseudo binary (1200 baud only) Transmit RF Out Connector Type N jack Radio Module OmniSAT-3 Operating Temperature -40° to +60°C Range Storage Temperature Range-55° to +75°C EUMETSAT DCP Radio EUMETSAT 2013-003-DCP-SDR Certification (2013-003) (17 July 2013) for standard rate (100 bps) EUMETSAT 2015-001-DCP- HDR (12 March 2015) for high rate (1200 bps) Accurate to 20 ms with GPS receiver. 15.88x 12.7 x4.57 cm (6.25 X 5x 1.81in) not including connectors 15.88x 14.99 x4.57 cm (6.25 x 59x18in)including Time-of-Day Clock Case Dimensions Maximum Dimensions connectors Weight 077kg (17 Ib) Supply Power Supply Voltage Range 10.5to 16 Vdc Typical Current Drain < 2.75 A when transmitting (typical 1.8Aat12Vdo)t04 A maximum < 5mA standby (typical 2.8 mA at 12Vdc) <40 mA during GPS acquisition (typical 25 mA at
