Hi all, firstly I apologise if this is posted in the wrong place. I'm currently doing a Mars rover project for university (just a concept design.) Basicly I am tasked with coming up with a communication system capable of relaying data back to Martian satellites from a rover on the surface. Atm the information I have is datalink can be open for about 20 mins transferling 70mb and at a range of approximately 100 200 miles to the satellite from the rover. The main considerations for this design are weight and volume. If there is any other information needed I will try to provide it. Hope one of you guys can help.
