This quora answer (https://www.quora.com/What-bands-signals-and-protocols-are-used-in-the-communication-from-the-Mars-rovers-satellites-to-Earths-NASA-ISRO-and-other-agencies https://www.quora.com/What-bands-signals-and-protocols-are-u...) claims that even the 70m DSN antennas have a hard time hearing the rover to earth transmissions. That is 10x the diameter so 1000x the surface area of a 4.8m dish like the one the guy built.
That said, there are no doubt interesting hacks you can do to help this but steerability is always going to be a concern to maximize the SNR of the very weak signal coming from the rover.
- jacquesm 8y agoYes, the precision required would be insane. That is also what makes this an interesting project, even if you fail you will still learn a ton about all kinds of engineering principles. Expensive lesson though! Another big factor would likely be how far Mars is away from Earth, at the close extreme it will probably be substantially easier to pull this off. What an interesting article by the way, thank you for that link.
