Seasat was the first Earth-orbiting satellite designed for remote sensing of the Earth's oceans and had on board one of the first spaceborne synthetic-aperture radar (SAR). The mission was designed to demonstrate the feasibility of global satellite monitoring of oceanographic phenomena and to help determine the requirements for an operational ocean remote sensing satellite system.
The Alaska Satellite Facility ( ASF) is a data processing facility and satellite-tracking ground station within the Geophysical Institute at the University of Alaska Fairbanks. [1] The facility’s mission is to make remote-sensing data accessible [2] Its work is central to polar processes research including wetlands, [3] glaciers, [4] sea ice ...
Satellite geodesy is geodesy by means of artificial satellites —the measurement of the form and dimensions of Earth, the location of objects on its surface and the figure of the Earth 's gravity field by means of artificial satellite techniques. It belongs to the broader field of space geodesy. Traditional astronomical geodesy is not commonly ...
TOPEX/Poseidon was a joint satellite altimeter mission between NASA, the U.S. space agency; and CNES, the French space agency, to map ocean surface topography. Launched on August 10, 1992, it was the first major oceanographic research satellite. TOPEX/Poseidon helped revolutionize oceanography by providing data previously impossible to obtain.
120–265 s. Propellant. UDMH / Red fuming nitric acid. The RM-81 Agena ( / ədʒinə /) was an American rocket upper stage and satellite bus which was developed by Lockheed Corporation initially for the canceled WS-117L reconnaissance satellite program. [1] Following the division of WS-117L into SAMOS and Corona for image intelligence, and ...
Venice Italy, captured 2023 from UMBRA satellite. The Alaska Satellite Facility provides production, archiving and distribution to the scientific community of SAR data products and tools from active and past missions, including the June 2013 release of newly processed, 35-year-old Seasat SAR imagery.
Space-based radar ( SBR) is a proposed constellation of active radar satellites for the United States Department of Defense. The SBR system would allow detection and tracking of aircraft, ocean-going vessels (similar to the Soviet US-A program), and potentially land vehicles from space. This information would then be relayed to regional and ...
After years of delays, in October 2023 Amazon (NASDAQ: AMZN) took its first step toward offering its very own satellite internet service. Competing with SpaceX's Starlink, Amazon launched a pair ...
