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. It has the characteristics of maintaining similar sun angles along its ground trace for all orbits, and typically has an inclination from 96 to 98 degrees, depending on the orbit altitude and orbit shape (eccentricity). See also synchronous orbit.

The DOST said Diwata-2 boasts of added features from the previous Diwata launched into orbit in April 2016, with a deployable solar panel, enhanced resolution cameras, a sun-synchronous orbit that will allow a fixed revisit interval and a larger area of coverage, an amateur ham radio unit for emergency satellite radio communications, an experimental altitude determination module and an omnidirectional sun-aspect sensor.
Talampas said Diwata-2 will also be staying longer in space at around three to five years, as it will be launched higher at 621 kilometers in a sun-synchronous orbit.
