text: 1,000 co-operative arrangements with over 100 countries. This is in addition to the numerous other agreements concluded by United States agencies such as the National Oceanic and Atmospheric Administration (NOAA). Other agreements invoive the development, launching, and operation of communications satellites, scientific satellites, or Earth sensing satellites. A typical example is the conduct of the Satellite Instructional Television Experiment (SITE) with India, which involves direct broadcast of national development information to rural areas on the Indian Sub-Continent from the NASA ATS-6 spacecraft. NASA has also provided considerable support in the use of geodetic aatellites for measurement of tectonic movement. Many agreements deal with various aspects of remote sensing·, including Landsat receiving, processing and data distribution. For example, in the remote sensing field, 14 ground stations outside the United States n_ow receive .data on a public, non-discriminatory basis for environmental and resource monitoring. 1 April 1990 is the thirtieth anniversary of the launch of the first United States weather satellite and marks the beginning of international co-operation in global environmental monitoring from space. This programme established the principle that satellite meteorological data should be openly available. Today well over 125 countries own meteorological satellite receiving stations and receive free of charge vitally important data for weather prediction, although formal agreements to receive such data are not required. Other agreements involve foreign experiments on United States satellites or other launch vehicles, for example, the large number of agreements involving the use of sounding rockets and balloons for upper atmospheric science and astrophysics investigations with countries of South America, as well as the Scandinavian Peninsula and the participation of the international scientific community in the upcoming Mission to Planet Earth.

analysis: The text discusses various international agreements and collaborations between the United States and other countries in the fields of satellite technology, remote sensing, and environmental monitoring. It highlights the sharing of satellite data for weather prediction, scientific research, and environmental monitoring, as well as the development of communication satellites and geodetic satellites. This suggests that the text is primarily focused on the scientific and technological aspects of international cooperation.
