The earth observation satellites (more specifically – environmental monitoring satellites) have one of two types of orbits: geosynchronous or sun-synchronous. Satellites that we’re interested in are the sun-synchronous satellites.

Sun-synchronous satellites pass over a point on the Earth at the same time each day, therefore, approximate time when a satellite will pass by a certain location can be predicted.

Calculating the time the satellites are passing involves very complicated math + the geographic coordinates of where you are. The predicted schedule below is provided by Heavens Above, and we promise it’s accurate!

Here is when the targeted satellites are passing by Los Angeles County:
