Most satellites for earth observation use sun-synchronous orbits. These orbits let the satellite's cameras take pictures ob objects at the same solar time. This means that it will pass overhead at the same local time every day
... so the images will have the same shadow characteristics.
You accomplish this by making the orbit precess exactly 360 degrees per solar year.
These orbits are typically nearly circular, but needn't be; you can put a spy satellite into a sun-synchronous elliptical orbit, so it'll swoops down and photograph near perigee, then waste a lot of time around apogee.
Since this orbit is around 684 Km, it can be shown that it must be pretty close to circular, has an orbital period of around 100 minutes, and its inclination is probably about 96 to 100 degrees (meaning that the satellite is slightly retrograde - 90 degrees inclination is polar, zero degrees is equatorial) In turn, this means that pretty much all of earth will be seen by the satellite, except for 8 degree circles around the poles.
A 96 minute period means that each successive orbit will look down on a place 15 degrees west
... one time zone to the west.
