The ground 'receiver' we are building is a 70cm telescope
Contrast that with the 18 meter RF dishes used to receive transmissions from the moon.
In the Lunar Laser Communications Demonstration the ground receiver was four 40cm telescopes. The space transmitter was a 10cm diameter telescope transmitting 0.5 Watts of laser power. That was able to transmit 622 Mbps - the highest data rate yet achieved from the moon.
We are building the terminal we are working on to do transmit and receive. The transmit will consist of four 15cm diameter off-axis parabolic telescopes. Each capable of transmitting up to 20 Watts.
