I don't know if that mirror is going to do much. I remember a Scientific American "Amateur Scientist" article back in 1969 or 1970 that should have been titled "high school kids build death ray" (our high school had them bound by the year). It was a CO2 laser that involved blowing glass. Several watts. Infrared, which makes it rather dangerous as you might notice it from your hand burning (Danger! Do not look into laser with remaining eye!). For infrared, regular mirrors won't work. I seem to remember the article said that glass shatters immediately when placed in the beam. To track the satellites, you need to check their orbital elements: https://en.wikipedia.org/wiki/Orbital_elements https://en.wikipedia.org/wiki/Orbital_elements https://www.space-track.org/auth/login https://www.space-track.org/auth/login (space force) https://orbit.ing-now.com/ https://orbit.ing-now.com/ (annoying ads) Good luck!
