Correct option is A
Polar Earth Orbit (PEO): The Polar Earth Orbit is commonly used for earth observation and reconnaissance satellites. It orbits around the Earth passing over the poles, and its altitude typically ranges from 500 – 2000 km above the Earth. This allows for global coverage as the Earth rotates beneath the satellite.
Parking Orbit: A Parking Orbit is a temporary orbit used for spacecraft before proceeding to a final mission orbit or interplanetary destination. These orbits are often at a low altitude, typically around 700 – 800 km, allowing for efficient launch and maneuvering.
Sun Synchronous Orbit (SSO): Sun-synchronous orbits are designed so that the satellite passes over any given point of the Earth's surface at the same local solar time. This orbit is particularly useful for Earth observation satellites. The typical altitude is around 700 – 800 km.
Geo-Synchronous Orbit (GSO): A geo-synchronous orbit is an orbit around the Earth where the satellite takes exactly 24 hours to complete one orbit, matching the Earth's rotation period. The altitude for a geo-synchronous orbit is approximately 35,800 km above the equator. Geo-stationary satellites, a subset of geo-synchronous satellites, remain fixed above a specific point on the Earth's equator.
