DOYLE, President International Society for Photogrammetry and Remote Sensing ABSTRACT Satellite remote sensing systems are being developed by several nations. Landsat-4 was launched by NASA in July 1982 and is providing high quality data from the Multi Spectral Scanner and the Thematic Mapper. Several Space Shuttle Missions will have partial remote sensing payloads: syn- thetic aperture radar, film cameras, and electro-optical sensors. The USSR operates both film cameras in Salyut-7 and electro optical sensors on the Meteor spacecraft. France will launch the SPOT satellite with high resolution electro-optical sensors. The European Space Agency and Japan will launch systems dedicated to marine observations, followed by other spacecraft for land observations. India is operating small remote sensing satellites and Brazil, Netherlands, and Canada are studying future systems. Worldwide experience of many individuals and organizations with remote sensing data acquired from space, primarily Landsat-1, -2, and -3, has demonstrated its utility for land use classification, agricultural assessment, energy and resource exploration, and many other applications. On the basis of this favorable expe- rience several countries are developing new systems for operation in the decade of the 1980s. This review presents the situation at the beginning of 1983. Only systems designed for imaging the Earth are included; meteorological satellites and other types of non-imaging remote sensing satellites are not covered. Landsat-4 The most significant recent event in satellite remote sensing was the successful launch of Landsat-4 on 16 July 1982. The spacecraft was launched by the Delta 3920 expendable vehicle into a 705 km altitude, 98.29 inclination sun-synchronous orbit. As shown in Figure 1, the basic vehicle is the Multi-mission Modular Spacecraft (MMS), which provides power supply, attitude control, command and data handling, and on-orbit propulsion. The payload consists of the Multi-Spectral Scanner (MSS) and the Thematic Mapper (TM). The MSS is essentially the same as the instrument carried on Landsats -1, -2, and -3, with four Spectral bands, 80m pixel, and 185 km swath. The TM is a second generation multispectral scanner having six spectral bands in the visible and short wave infrared wavelengths with a 30m pixel, and one band in the thermal infrared wavelength with 120m pixel. The TM swath width is also 185 km. The spacecraft has a solar array for power, an antenna for use with the Global Positioning System (GPS)**, and a large steerable antenna for communication with the Tracking and Data Relay Satellite System (TDRSS)***, *Extensively revised from earlier version of April 1982. **The GPS will eventually consist of an array of 18 separate satellites arranged in six different orbital planes at 20,200 km altitude. By real time processing of the signals from GPS, it will be possible to determine the position of Landsat-4 with a precision of about 15 meters in all three coordinates. GPS should be fully operational in 1988. ***The TDRSS will consist of two communication satellites in geostationary orbits at 419 and 1719 west longitude and a single ground station at White Sands, New Mexico. Commands from the ground and data from manned and unmanned space- craft in low Earth orbit will be transmitted via TDRSS, thus eliminating the need for the current NASA Spacecraft Tracking and Data Network (STADAN). TDRSS should be operational by Fall 1983. 341
