TIROS-TIROS IV-------
SPACECRAFT DESCRIPTION:
The spacecraft was 42 inches in diameter, 19 inches high and weighed 285 pounds. The craft was made of aluminum alloy and stainless steel then covered by 9260 solar cells. The solar cells served to charge the 63 nickel-cadmium batteries.
A new lens system was implemented for this launch. The lens was designed to reduce distortion and improve resolution. This craft also contained an electronic clock to control the operations of the infrared horizon sensor as well as the magnetic orientation control system. A magnetic tape recorder was still provided for each camera to store photographs while the satellite was out of range of the ground station network. One scanning and two non-scanning radiometers were also on board. The transmitting and receiving antennas were of the same configuration as the previous TIROS models.
