Where did Arthur Eddington and a group of astronomers set up some telescopes to view the total solar eclipse in 1919?

• Brazil and on the island of Prinicpe, off the east coast of Africa

• Brazil and on the island of Prinicpe, off the west coast of Africa

• Brazil and on the island of Prinicpe, off the southeast coast of Africa

• Brazil and on the island of Prinicpe, off the north coast of Africa

In particular, what did the team of Eddington measured as the eclipsing sun was crossing over?

GPS works through the following mechanisms, except.

• The signal contains data that a receiver uses to compute the locations of the satellites and to make other adjustments needed for accurate positioning.

• The receiver uses the time difference between the time of signal reception and the broadcast time to compute the distance, or range, from the receiver to the satellite.

• The time information is placed in the codes broadcast by the satellite so that a receiver can continuously determine the time the signal was broadcast.

• The receiver must account for propagation delays, or decreases in the signal's speed caused by the troposphere alone. With information about the ranges to three satellites and the location of the satellite when the signal was sent, the receiver can compute its own two-dimensional position.

What does GPS satellites carry to provide extremely accurate time?
