NASA/Goddard Space Flight Center Selects Sutron's SatLink Satellite Transmitter to Aid in Monitoring Global Climate Change Data.

Business Editors

STERLING, Va.--(BUSINESS WIRE)--Sept. 21, 2001

Sutron Corporation announced today that NASA/Goddard Space Flight Center has made its first purchase of Sutron's SatLink High Data Rate Satellite Transmitter.

SatLink will be an important part of AERONET, the Center's global network of 165 remote sensing aerosol monitoring stations. AERONET's automatic data acquisition, transmission and processing facilitates building local, regional and global databases, fundamental for understanding the influence on climate change of atmospheric aerosols.

Three factors have positively impacted this important work.

1. Sutron's ability to interface with recently developed

weather-resistant automatic sun and sky scanning radiometers

to enable more frequent and comprehensive measurement of

aerosol optical properties at very remote locations;

2. Sutron's ability to transmit automatic real-time measurements

via several geostationary satellites (GOES, METEOSAT, GMS and

INSAT) thus providing 100 percent global coverage; and

3. Development of Sutron's SatLink, a satellite transmitter which

will send data at 12 times the previous rate.

NASA and its international partners have indicated they have implemented a program to replace existing transmitters with Sutron's SatLink Satellite High Data Rate Transmitters in all 165 stations in the near future.

Sutron is also a major supplier of real-time environmental remote monitoring and control systems for other Federal Agencies, including the US Geological Survey, the US Army Corps of Engineers, the National Ocean Service, a division of the National Oceanic and Atmospheric Administration, and the National Weather Service.

For 26 years Sutron has designed and manufactured environmental monitoring and communication equipment that operates unattended in remote, inhospitable places, under the most extreme conditions on the planet.

With over 25,000 environmental monitoring stations presently in operation globally, Sutron is a major worldwide supplier of real-time data collection systems that include telemetry, sensors, and data management software.
