What is the primary application of Highly Elliptical Orbit?

• A. Positioning, navigation, and timing, as well as communication over high latitudes
• B. Weather observation and environmental monitoring
• C. Deep-space science missions
• D. Earth imaging and surveillance

Answer: (B)

Highly Elliptical Orbits are designed so a satellite spends a long time over high-latitude regions when it’s near apogee. That long dwell time over polar areas makes it especially effective for collecting environmental data and weather-related measurements, since you can repeatedly sample atmospheric conditions, surface temperatures, cloud cover, and other environmental parameters during each pass. Because the satellite lingers over these regions, satellites in this orbit can provide timely, frequent data for weather observation and environmental monitoring, which is why that application is the most fitting here. While HEO can be used for high-latitude communications as well, the emphasis in this context is on data collection for weather and environmental purposes.
