“geo-synchronous lunar orbit”? Perhaps “lunar-synchronous” would be better. If the moon makes a complete rotation in about 28 days, how “high” above the moon would that satellite have to be?

On another note, I have always thought that the moon would make a great place to base an observatory. The near side to examine the earth, and the far side to investigate the rest of the universe.

Lunar synchronus orbit may not even exist. The earth gravity disturbances for something that far away from the moon to have a 30 day orbit would likely wreck the orbit before it got through the first revolution

It would make a great place to put some telescopes in an array combined with some on earth. Currently our telescope arrays are only as large as the diameter of the earth. Adding telescopes to the moon increases the size of the array to nearly 500,000 miles.

I actually did study “rocket science”when I lived in America and we did a project for the far side of the moon.

I was the engineer on the team, so whilst the others designed their far-side spectrometers and whatnot, I calculcated how to put a satellite at one of the earth-moon lagrange points in a halo orbit to provide continous communication with earth. Btw, 24-7 communication would probably not be needed anyhow, but it is very possible.
