ICESat-2 Por Los Números: 90

The video tutorial explains how lasers are used to measure slopes in a single satellite pass. It covers the path of the Atlas laser and the setup involving three pairs of aces separated by 90 meters. The tutorial details how scientists calculate elevation changes even if the laser beams are slightly off from their initial positions.

What is the primary purpose of using lasers in satellite technology?

• To measure the speed of the satellite

• To calculate the slope in a single pass

• To communicate with ground stations

• To determine the satellite's orbit

How are the laser pairs arranged in the satellite system?

• Stacked vertically

• In a straight line

• In a circular pattern

• Separated by 90 meters

What is the distance between the pairs of lasers?

• 90 meters

• 110 meters

• 70 meters

• 50 meters

What is the role of the reference track in laser measurements?

• To adjust the laser's intensity

• To measure the speed of the laser

• To provide a baseline for elevation calculations

• To guide the satellite's path

How do scientists handle slight misalignments in laser beams?

• By calculating elevation changes regardless

• By ignoring the data

• By adjusting the satellite's position

• By recalibrating the lasers
