GOES SATELLITE - USER EQUIPMENT ANTENNAS

Seavey Engineering produces uplink and downlink antennas accessing the SMS/GOES satellites operated by National Oceanic and Atmospheric Administration (NOAA). The SMS (Synchronous Meteorological Satellite) and GOES (Geostationary Operational Environmental Satellite) platforms perform remote sensing of weather patterns; they also observe the sun and are used to relay data from remote land stations which monitor various functions such as river water levels, snow cover, atmospheric data, glacial movements, and other environmental parameters.Standard uplink frequency for the remote land platforms is 402 MHz with right-hand circular polarization. Typical uplink antennas are specified to have gains ranging from 3 - 15 dBi.The assigned downlink frequency is 1665 - 1700 MHz with linear polarization. For antennas accessing several GOES satellites, it may be desirable to provide remote orientation of the linear polarization. The model GFR-1 antenna feed does this. For most down-link systems, parabolic antennas with diameters of 6 - 20 feet are employed.Antennas for the 468 MHz downlink timing signal are also available on request. Please refer to Page 35 for antennas which can be used for both GOES satellite work plus other satellite imagery applications.
