SPACECRAFT DESCRIPTION:
The spacecraft was a cylinder 75 inches in diameter, 103 inches high and weighed 630 pounds. The sides of the cylinder were covered by 15,000 solar cells which, along with nicad batteries, provided the power for the craft. A single triangular magnetometer unit was located on the top of the craft which extended 33". The spacecraft was spin stabilized and rotated at 100 revolutions per minute.
The principle instrument on board was the Visible Infrared Spin Scan Radiometer (VISSR) which provided day and night imagery of cloud conditions over the full-disk. The satellite had the capability to continuously monitor cataclysmic weather events such as hurricanes and typhoons, relay meteorological data from over 10,000 surface locations into a central processing center for incorporation into numerical weather prediction models, and to perform facsimile transmission of processed images and weather maps to WEFAX field stations. In addition, a Space Environment Monitor (SEM) and Data Collection System (DCS) similar to those on the NOAA polar orbiters were installed.
