Which type of orbit allows a satellite to pass over a section of the E...
Explanation:
Sun Synchronous Orbit:
Sun-synchronous orbit is a type of polar orbit that allows a satellite to pass over a section of the Earth at the same local solar time each day. This means that the satellite will always cross the equator at the same time, providing consistent lighting conditions for imaging and data collection.
Characteristics of Sun Synchronous Orbit:
- The inclination of the orbit is typically around 98 degrees.
- The satellite crosses the equator at the same local solar time on each pass.
- The orbit precesses due to the gravitational effects of the Earth's oblateness, maintaining the same solar time for each pass.
Advantages of Sun Synchronous Orbit:
- Allows for consistent lighting conditions for Earth observation satellites.
- Provides a predictable and repeatable ground track for data collection.
- Enables efficient use of onboard power systems due to consistent solar illumination.
Applications of Sun Synchronous Orbit:
- Earth observation and remote sensing for environmental monitoring, agriculture, and disaster response.
- Climate research and monitoring of ice caps, oceans, and forests.
- Weather forecasting and atmospheric studies.
In conclusion, a Sun Synchronous Orbit is the type of orbit that allows a satellite to pass over a section of the Earth at the same time of day, making it ideal for various Earth observation and scientific missions.
