Overview
The Seasat spacecraft was launched in late June 1978, and during its brief
110-day lifetime, collected 90 days of nearly continuous radar altimeter
data between the latitudes of 72 deg South and 72 deg North. The spacecraft
maintained its 108 degree inclination, performing in a 17-day repeat
groundtrack until September 9 and then a 3-day repeat pattern until it stopped
operations on October 10. Although designed only for measurements over
water, the Seasat radar altimeter acquired more than 600,000 useful
altimeter range measurements over the continental ice sheets of Greenland
and Antarctica. Processing of the ice altimetry returns are explained in more
detail in Martin et al., 1983
