RAWS-F Remote Automated Weather Station for Fire Weather

5.4 GOES Transmitter (part #TX312) (Optional)

5.4.1 General Description, GOES Transmitter (part #TX312)

The High Data Rate GOES transmitter (part #TX312) shown in Figure 5.4-1

supports one-way communication, via satellite, from a Campbell Scientific

datalogger to a ground receiving station. Satellite telemetry offers a convenient

communication alternative for field stations where phone systems or RF

systems are impractical or rendered unreliable after a tragedy to the local

infrastructure. Data transmission rates of 100, 300, and 1200 bps are

supported. Because clock accuracy is critically important for GOES satellite

telemetry, the TX312 includes a robust, TCXO-based real-time clock and a

GPS receiver.

The TX312 transmitter has two siting requirements for proper operation. The

GOES antenna must have a clear view of the spacecraft. The GOES antenna is

directional and should be aimed at the spacecraft. Both elevation and azimuth

are unique to the location of the planet and must be set. A poorly aimed

antenna will cause a drop in signal strength or possibly prevent successful

transmission.

For more information on the GOES transmitter (part #TX312) and antenna

siting, go to our website at www.campbellsci.com

, enter the “TX312” in the

“Search” box on the website mentioned above, and go the equipment manual.

The GOES transmitter (part #TX312) manual is also provided on the Resource

CD which ships with the RAWS Quick Deployment Weather Station.

The spacecraft specific DCP-Setup parameters for the GOES

transmitter must be entered in the CR1000KD menus for the

GOES transmitter TX312 to work properly. If the RAWS Quick

Deployment Weather Station does NOT have a GOES

transmitter disregard the DCP-Setup parameters.
