Satellite Technology and Its Impact

What event marked the beginning of the space exploration race?

• The moon landing

• The launch of Explorer 1

• The launch of Sputnik

• The launch of Hubble Telescope

Which type of orbit is best suited for detailed imaging and scientific missions?

• Highly Elliptical Orbit

• Low Earth Orbit

• Geostationary Orbit

• Medium Earth Orbit

What is the primary advantage of satellites positioned at Lagrange points?

• They can orbit faster than other satellites.

• They remain stationary relative to Earth and another celestial body.

• They require less energy to maintain orbit.

• They can communicate with more ground stations.

What is the main source of energy for most modern satellites?

• Hydroelectric power

• Solar panels

• Wind energy

• Nuclear power

How do GPS receivers determine their exact position?

• By using ground-based stations

• By using a single satellite signal

• By measuring distance from at least four satellites

• By calculating the speed of light

What is trilateration used for in GPS technology?

• To measure the speed of satellites

• To find a location by measuring distances from known points

• To calculate the orbit of satellites

• To enhance signal strength

What is a significant concern related to the increase in the number of satellites?

• Decreased accuracy of GPS systems

• Space debris and the cascading effect

• Limited bandwidth for communication

• Increased cost of satellite launches

What is a mega-constellation in satellite technology?

• A single large satellite

• A network of hundreds or thousands of satellites

• A constellation of stars

• A group of satellites orbiting the moon

Which company is known for its mega-constellation project called Starlink?

• SpaceX

• NASA

• Virgin Galactic

• Blue Origin

What is one method being considered to address the issue of space debris?

• Safer satellite decommissioning and debris removal

• Launching more satellites to push debris away

• Increasing the size of satellites

• Using nuclear-powered satellites
