How does inclination affect a satellite's ground trace?

• A. It determines its orbital velocity
• B. It defines the maximum latitudes covered
• C. It decreases the coverage area
• D. It increases the satellite's weight

Answer: (B)

Inclination plays a significant role in a satellite's ground trace as it defines the maximum latitudes that the satellite can cover during its orbit. A satellite's inclination is the angle between its orbital plane and the equatorial plane of the Earth. When the inclination is zero degrees, the satellite orbits directly above the equator, and its ground trace remains confined to the equatorial region. As the inclination increases towards 90 degrees, the satellite moves into a polar orbit, allowing it to pass over the maximum latitudes of the Earth, effectively covering the entire surface from pole to pole. Therefore, the inclination determines how far north or south a satellite can travel in its orbit and, consequently, impacts the areas of the Earth that can be monitored or serviced by the satellite. The other options do not correctly capture the purpose of inclination in terms of ground trace. Orbital velocity is influenced more significantly by altitude and the gravitational pull of the Earth rather than inclination itself. While coverage area is related to how inclination is defined, it does not correctly identify the relationship as maximum latitudes. Inclination does not inherently decrease coverage; rather, the angle can limit or enhance coverage depending on its value. Lastly, the weight of a satellite is determined by its
