TIROS-7 Objectives:
Continue research and development of the meteorological
satellite information system; obtain improved data for use in
weather forecasting, especially during hurricane season.
Description:
The spacecraft was 42 inches in diameter, 19 inches high and
weighed 270 pounds. The craft was made of aluminum alloy and
stainless steel then covered by 9200 solar cells. The solar
cells served to charge the nickel-cadmium (nicad)
batteries. Three pairs of solid-propellant spin rockets were
mounted on the base plate.
TIROS-7 was also designed to make infrared measurements of
reflected solar and terrestrial radiation over selected spectrum
ranges and gather data on electron density and temperature in
space. To accomplish this new expanded mission, TIROS-7 carried
two wide-angle camera systems, a magnetic tape recorder, and
infrared experimentation equipment. The electron density and
temperature probes were the same as the ones flown on board
Explorer 17.
The spacecraft operating system still included the infrared
horizon scanner, the north direction indicator, despin weights
and spinup rockets, and the magnetic attitude control
system. TIROS-7 was deactivated after furnishing over 30,000
cloud photographs; it lasted the longest of the TIROS series
thus far, 1809 days.
Experiments on Tiros-7:
Low-Resolution Omnidirectional Radiometer
Scanning Radiometer
Langmuir Probe
Television Camera System
