Technische Beschreibung
The TX321 is designed for use on the NOAA GOES Data Collection System and the EUMETSAT Meteosat Data Collection Services satellite networks. These networks use geostationary satellites and ground stations to receive and relay data transmitted from remote data collection platforms (DCP), such as those provided by Campbell Scientific. These DCPs are typically owned and operated by government agencies and sponsored research organizations. Users are given a frequency and time slot for their transmissions.
Data Collection Platform (DCP) Equipment
- TX321 Satellite Transmitter
- 17992 or 31182 GPS antenna and their antenna mounts and coaxial cables
- 25316 11 dBi Right-Hand Circular Polarized (RHCP) Yagi antenna and coaxial cable
- Data logger
- Power supply, such as Campbell Scientific’s BP12 or BP24 battery, CH150 or CH200 charge regulator, and SP10 10 W or SP20 20 W solar panel
GOES System Authorization Procedure
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:
- Fill out the System Use Agreement (SUA) application form. The form can be submitted online or sent to:
GOES DCS SUA Processing Unit NOAA,
Satellite Services Division
4231 Suitland Road, Rm 1646
Suitland Federal Center Suitland, MD 20746
Tel: 301-817-4563
Fax: 301-817-4569
Email: Letecia.Reeves@noaa.gov - Following approval, NESDIS sends a Memorandum of Agreement (MOA). The MOA must be signed and returned to NESDIS.
- After the MOA is approved, NESDIS will issue a channel assignment and an ID address code.
- NESDIS must be contacted to coordinate a start-up date.
Meteosat System Authorization Procedure
Complete and submit the EUMETSAT DCP Admission form.

Additional Compatibility Information
Power Supply
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 can be used if the system contains higher power consumptive devices such as continuous bubblers or heated rain gages.
Note: Because of the peak power draw during transmit, do not connect to the 12V output of a data logger.
