What did Bradford Parkinson receive as an award or his impacton the GPS satellite project? A MedalA Nobel Piece PrizeA Charles Stark Draper PrizeA Chocolate Bar2. Roughly how many SD services can you have on a single transponder? 1205123. According to Kepler's laws, the paths of planets about the sun are Ellipses.Straight lines.Parabolas.Circles.4. The radial velocity of an Earth satellite is its velocityPerpendicular to the surface of the Earth.None of theseParallel to the surface of the Earth.Attributed to satellites moving in any direction.5. How many of the launches of the GPS satellites have failed? 31125All but 246. Consider a moon that orbits one of our most distant planets in an elliptical path. The distance that the moon covers each day isGreatest when the moon is furthest from the planet.The same regardless of its distance from the sun.Greatest when the moon is closest to the planet.The same regardless of its distance from the planet.7. Which type of satellite is used to monitor atmospheric conditionscommunicationweatherreconnaissanceobservation8. A lunar month is about 28 days. If the moon were closer to the Earth than it is now, the lunar month would be Unchanged at 28 daysLess than 28 days.None of the aboveMore than 28 days.9. The Sputnik 1 was lauched by which country JapanU.S.AFranceAustralia10. Which planet has one moonMecuryVenusEarthMars11. The circular path of a satellite orbiting the Earth is characterized by a constantRadial distance.All of theseSpeed.Acceleration.12. A lunar month is about 28 days. If the moon were farther from the Earth than it is now, the lunar month would be Less than 28 days.Difficult to predict without much more information.About 28 days.More than 28 days.13. The speeds of the planets about the sun depend onTheir distances from the sun.Their periods of rotation.None of the above are correct.The masses of the planets.14. A satellite describes an elliptical orbit about a planet. The satellite travels much faster when it is directly over aHigh mountain range.None of the above choices affects its speed very much.Great plain or plateau.Large island.Large ocean.15.

Which type of satellite is used for sending messages from one place to anotherreconnaissanceCommunicationobservationweather17. When was the first GPS satellite launched into space? 197918841984197818. Moving a transponder from their between uplink antennas is called an IOT?TrueFalse19. What prevents satellites such as the space shuttle from falling?Centrifugal forceNothing; they are continually falling as they orbit the Earth.The absence of air dragGravityCentripetal force20.
