Are satellites engineered differently for specific planetary orbits?

I'm currently doing an assignment on Mars colonisation and launching a GPS satellite system there. Would we have to engineer these satellites differently to make them orbit Mars in a way that could be used for GPS?

I'm having trouble on finding any information about making different satellites for different planets, maybe I'm just bad at google, but if someone could provide some information (and hopefully sources?) it'd be greatly appreciated.

Mars is farther from the sun so for the same amount of power you would need bigger solar panels. 

Mars has less mass so there are relativistic effects which need to be accounted for. 

Orbits would be different for the same GPS coverage as Earth.
