[Starlink] Quick questions about Starlink user terminal

[Eugene Y Chang]

Usually it is deliberate that equipment does not transmit while receiving. This is to prevent the transmit power from overloading the receiver. This problem can be avoided if the TX and RX are on widely separated freaquencies and antenna configurations to keep the TX signal out of the RX signal path.

What do we know about Starlink’s use of laser links for satellite-to-satellite communications? I am most curious about the challenges of pointing the laser at a moving target.
