Advantages of Sun synchronous orbit | disadvantages of Sun synchronous orbit
This page covers advantages and disadvantages of Sun synchronous orbit and its basics.It mentions benefits or advantages of Sun synchronous orbit and drawbacks or disadvantages of Sun synchronous orbit.
What is Sun synchronous orbit?
Introduction:
An earth satellite orbit in which the orbital plane is near polar and the altitude is such thatsatellite passes over all places on earth having same latitude twice in each orbit at the same local suntime.This orbit lies at a altitude between 700 to 800 Km above the Earth.
The satellite in this orbit shift its orbital plane by approx. one degree/day.Satellites put in this orbit cover each area of the world at a constant local time of the day called local sun time.

- A Sun-synchronous orbit crosses over the equator at approximately the same local time each day (and night). This orbit allows consistent scientific observations with the angle between the Sun and the Earth’s surface remaining relatively constant. These illustrations show 3 consecutive orbits of a sun-synchronous satellite with an equatorial.
Benefits or advantages of Sun synchronous orbit
Following are the benefits or advantages of Sun synchronous orbit:
➨The orbit is designed in such a way that angle between orbital plane and sun remains constantresulting into consistent lighting conditions.
➨The satellites in this orbit can help in monitoring activities near the poles unlike other satellites.
➨The Sun synchronous orbiting satellites cover entire globe on regular basis and provides repetitive coverage on periodic basis.Satellite passes over all places on earth having same latitude twice in each orbit at the same local suntime.
➨Low altitude of this orbit allows good ground resolution.
➨It offers easy active measurements with the help of Radar or using Lidar.
Sun-synchronous orbit An orbit in which the satellite's orbital plane is at a fixed orientation to the sun, i.e., the orbit precesses about the earth at the same rate that the earth orbits the sun.
Drawbacks or disadvantages of Sun synchronous orbit
Following are the drawbacks or disadvantages of Sun synchronous orbit:
➨The satellite launched in this orbit can not view a particular spot on the Earth's surface continuously.This is done by geosynchronous orbiting satellite.
➨For weather forecasting the use of polar orbiting satellite data is limited unlike Geosynchronous orbiting satellite.
➨Sun synchronous orbiting satellite passes over polar parts on every orbital period which is 2 times a day where asgeosynchronous orbiting satellite orbital period is approx. 24 hours. Hence Geosynchronous satellite can view a particular spot on the Earth's surface continuously.
Conclusion: In order to understand advantages of Sun synchronous orbit and disadvantages of Sun synchronous orbit one has to understandSun synchronous orbit basics >>.
