Seasat – Processing and Tools
Seasat data required cleaning before processing it into imagery. The data product packages were eventually distributed in HDF5 and GeoTIFF format.

Seasat – Technical Challenges – 7. Cleaned Swath Files
Seasat synthetic aperture radar (SAR) data holdings at ASF have been converted from their original 29 SONY SD1-1300L tapes into raw swath files with external metadata stored on disk. As detailed elsewhere in these pages, a total of 1,346 decoded, cleaned swath files were created.

Seasat – Product Specification Guide
During its brief 106-days of lifetime, the Seasat-1 spacecraft, launched on June 28, 1978, by NASA’s Jet Propulsion Laboratory (JPL), collected information on sea-surface winds, sea-surface temperatures, wave heights, internal waves, atmospheric water, sea ice features, ice sheet topography, and ocean topography. This was the first JPL mission to study Earth with the use of imaging radar.
Seasat – Technical Challenges – 1. Raw Telemetry
Seasat was not equipped with an onboard recorder, so in order to collect data during the mission, three U.S. and two international ground stations downlinked data from the satellite in real time: Fairbanks, Alaska; Goldstone, California; Merritt Island, Florida; Shoe Cove, Newfoundland; and Oakhanger, United Kingdom. The data were originally archived on 39-track raw data …

Seasat – About
Seasat was the first NASA satellite with synthetic aperture radar deployed. It operated on L-band in 1978 for 105 days until its catastrophic power failure.

Seasat – Technical Challenges
The Alaska Satellite Facility was tasked by NASA with creating a digital archive of focused synthetic aperture radar (SAR) products from data collected by NASA’s Seasat mission. The basic steps involved in this process are as follows: Capture the raw signal data from tape onto disk Validate and byte-align the raw signal data Decode the …
