GPS - Extra notes Questions with Correct Answers (Grade A+)
Question 1: GPS: A Global Navigation Satellite System that allows us to locate things on the surface of
the Earth with extraordinary accuracy using a network of ________ satellites that continuously
transmit _________ radio signals.
Answer: 24, high-frequency
Question 2: GNSS
Answer: Global Navigation Satellite System
Question 3: ____ is the U.S. Global Navigation Satellite System (GNSS). It is a network of satellites that
contain time and distance date and allows the user to pinpoint their postion anywhere on Earth.
Answer: GPS
Question 4: Global navigation satellites continuously transmit time and distance information as they
orbit the earth in a precise formation. Information is used to calculate an exact location through
triangulation.
Answer: how satellite navigation works
Question 5: Satellite navigation receivers operate by __________ with global positioning satellites. This
means that at least three satellites must be in _______ of a receiver for calculation of longitude and
latitude while a fourth satellite must also be within line of sight to calculate altitude.
Answer: line of sight, view
Question 6: Line of Sight: At least ______ satellites must be in view of a receiver to calculate longitude
and latitude as a ________ satellite calculates altitude.
Answer: three, fourth
Question 7: DGPS
Answer: Differential Global Positioning Service
Question 8: DGPS: Differential Global Positioning Service. DGPS offers enhanced locational
measurements through the use of radio beacons that provide corrections.
Answer: beacons
