{ =] SCIENTIFIC WHEN MEASUREMENTS MATTER Overview The TX321 is a GOES and Meteosat satellite data transmitter. It provides an easy and reliable way for Campbell Scientific data collection platforms (DCP) to transmit data over Benefits and Features ) GOES High Data Rate Version 2, Meteosat SRD, and International DCS operation ) Very low power consumption when idle (< 5 mA @ 12V) ) Transmissions continue for 28 days if GPS is lost Technical Description 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 For comprehensive details, visit: www.campbellsci.eu/tx321 W R(REE TX321 Satellite Transmitter for GOES or Meteosat TX321-G geostationary satellites. The TX321 is typically used by government agencies and sponsored research organizations for the purpose of collecting environmental data. ) Configuration and diagnostics easily performed by data logger or computer ) Drop-in replacement for Campbell Scientific TX320, TX312, and SAT HDR GOES ) 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: 1. 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

Fax:301-81 7-4569 Email: Letecia.Reeves@noaa.gov 2. Following approval, NESDIS sends a Memorandum of Agreement (MOA). The MOA must be signed and returned to NESDIS. 3. After the MOA is approved, NESDIS will issue a channel assignment and an D address code.
