CFOSAT Orbit

The CFOSAT orbit will be repetitive with a 13-day cycle, sun-synchronous, at an altitude of 520 km and a inclination of 97.4°.

 

Orbit requirements

A global coverage and a more frequent sampling lead to a good compromise on the repetitivity at 13 days.

The inclination allows a sun-synchronous orbit in order to minimize tides aliasing and monitor main water bodies on continents.
