BACKGROUND: Stereosat is a NASA Scout-Applications Explorer Mission supported : P
by the Geosat Committee. (uw
Geosat Committee: Incorporated in 1976 as a nonprofit organization
Supported entirely by contributions from industrial firms
Seeks to consolidate industrial needs for pertinent,
geologically related objectives into federally
sponsored remote sensing programs
PURPOSE: Cloudfree stereoscopic multispectral coverage from space of the
world's land mass to be obtained in a two-year period.
Useful for rock discrimination, structural interpretation, geomorphic
analysis, and general geologic mapping.

ORBIT: Polar, sun-synchronous
Altitude: 578 km
Period: 96.1 minutes
PROPOSED IMAGING SYSTEM: To provide black-and-white stereo coverage in near
infrared in digital form to register with Landsat
Configuration - Single camera head, two telescopes, four sensors
Telescope - 600 mm, f/8 refractor
Sensor - Linear array of silicon photodiodes, 1872 elements
Full stereo angle - 60 degrees
Pixel footprint | - 19.3 m along track by 16.7 m cross track
Svath width - 31.2 km
DATA TRANSMISSION: In real time through TDRSS
Backup data storage on 2 onboard digital tape recorders,
each with 4 x 10° bit capacity; 8.1 mbps maximum rate
