You can actually see the video feed blip out once per revolution. I assume it's because the transmitter is briefly pointing away from the receiver.

- rdtsc 11y agoYeah noticed, but I was suprised it wasn't actually completely black but with just quick flash of an image once in a while.
- ramidarigaz 11y agoYeah. The coverage area of the transmitter must be massive.
- colechristensen 11y agoIt's likely an omnidirectional antenna on the satellite and a (very directional) tens-of-meters ground station (or series of them) following the satellite's position.
- ars 11y agoOr the antenna is always mostly in the direction of earth, and the spin (from the point of view of the earth) just has the antenna describe a circle.
