PASADENA, Calif., Dec. 3 (AScribe Newswire) -- Researchers at NASA's Jet Propulsion Laboratory, Pasadena, Calif., have conducted groundbreaking research, proving that Global Positioning System altimetry may be an inexpensive, effective tool to measure sea levels.
Altimetry uses special instruments that measure height. The findings come from an experiment at Crater Lake in Oregon. It disproved the idea that Global Positioning System signals are too weak to provide accurate sea level measurements.
The goal was to first test the technology's capability over a lake, with the eventual goal of testing it over the ...
