Campbell Scientific’s TX320 is a high data rate (HDR) transmitter that provides communications, via GOES satellites, from a Data Collection Platform (DCP) to a receiving station. It is compatible with most Campbell Scientific dataloggers and offers a convenient telemetry option for remote DCPs in the Western Hemisphere.Read More
The TX320 supports data transmission rates of 300 and 1200 bps. Because clock accuracy is critically important for GOES satellite telemetry, the TX320 includes a robust, temperature-compensated-oscillator (TCXO) based clock and a GPS receiver. The real-time clock's precision allows independent operation for up to 28 days without GPS correction.
GOES satellites have orbits that coincide with the Earth’s rotation, allowing each satellite to remain above a specific region. GOES satellites cover the western hemisphere.
The GOES system is administered by the National Environmental Satellite Data Information Service (NESDIS). NESDIS assigns addresses, uplink channels, and self-timed/random transmit time windows. Self-timed windows allow data transmission only during a predetermined time frame. Random windows are for applications of a critical nature (e.g., flood reporting) and allow transmission immediately after a threshold has been exceeded.
Choose one of the following methods:
1 - ASCII command protocol is described in “G5 ASCII Command Protocol (Document number 700-G5-CMND-ASCII)."
2 - Binary packet protocol is described in “G5 Binary Command Protocol (Document number 700-G5-CMND-BIN)."
Please note: The following shows notable compatibility information. It is not a comprehensive list of all compatible products.
|CR10 (retired)||The CR10 requires a special PROM.|
|CR10X (retired)||For a mixed-array CR10X, use OS version 1, revision 15 through 19. For CR10X-PB, use the most current operating system; the RAWS-7 format is not supported by the CR10X-PB.|
The TX320 transmitter needs to be housed in an ENC16/18, ENC24/30, or ENC24/30S environmental enclosure. You can order the enclosure with the 19332 and 19336 Antenna Cable/Bulkhead accessories that will allow the Yagi and GPS antennas to be connected without opening the enclosure door.
Typical power supply is a BP12 12 Ahr or BP24 24 Ahr battery, CH150 or CH200 regulator, and an SP10 or SP20 solar panel. The BP85 or a user-supplied deep-cycle rechargeable battery should be used when it is difficult to replace the batteries or the system's power requirements are large. The deep-cycle rechargeable battery should have at least a 60 Ahr capacity, and be trickle-charged with an 20 W solar panel.
Non-U. S. government agencies and research organizations must have a sponsor from a U.S. government agency. Prospective GOES users must receive formal permission from NESDIS, by doing the following:
