    Scientists Use GPS Signals to Measure Earth’s Atmosphere

    Using a technique originally developed in the 1960s for understanding the atmospheric properties of far-away planets, scientists around the world have been using radio signals from GPS satellites to learn more about the atmosphere of our own planet.

    That technique, which is known as radio occultation, was pioneered by NASA’s Jet Propulsion Laboratory and Stanford University. When a planet occults, or passes in front of, a star, the star’s brightness decreases. The amount of the decrease can be used to approximate the height of the planet’s atmosphere. When radio waves emitted by the star pass through the planet’s atmosphere, they bend and change frequency, and this change can be measured to determine the atmospheric composition.

    Think of every possible use for a device that gives an accurate, fixed position on the earth.

    Navigation for cars, planes, ships, missiles, satellites. Mapping datum for cartography, surveying, archaeology, geology, etc. Useful for any research that involves tracking something; an object, an animal, a person.

    Google it!
