LMAO you're really doubling down?

No, they absolutely will not notice a 30ms delay. Why would you even say something so absurd?

You have the same issue with Starlink…

No, because the Starlink satellites are 350 miles above the Earth while geosynchronous satellites are 13,000 miles above the earth. Because of the Inverse-Square Law they can transmit a signal that is orders of magnitude stronger.

In addition, geosync satellites are locked at a single fixed position and received by a single dish antenna so any obstruction along the line will disrupt the signal.

Starlink’s recievers use a 1200 element x-band phased array so it can lock on to multiple sources and track them as they move across the sky. Each satellite link is its own channel. Losing contact with one satellite simply causes the data to be routed to one of the 4-5 other locked satellites.

30ms of latency is less than 1/3rd of the latency of most Bluetooth headsets that people use every day to talk on their phones. It is not noticeable at all.
