I have a question about using the Raspberry Pi with a GPS. I just bought a serial GPS (BU-353) for use with my pi. I tested it on my standfalone using Google Earth and it works fine so i knwo that my pi will be able to work out were it is located.
however what if i also need to know which direction my pi is pointing in or facing? Will my serial gps give me this information or do I need to use a separate compass modele? I realise that if the pi is moving i can work out which direction it is travelling but what i really need to know is - which way is it facing, even when it s not moving?
Will my GPS tell me this or do I need a separate compass module?
