7 This should be pretty easy, but if you want help with it, you're going to need to give us some insight into how you're storing or accessing the GPS data at present.
9 Having said that, I'm not convinced that this is necessary. I have a logfile here with 91,000 lines of text in it, and it's 9.9mb and bzips down to 369kb. 91,000 is close to 10 entries every minute for a week, and I'd guess that you'd find CSV formatted GPS data written as text to have about the same length and compressibility as a typical /var/log/messages entry.

15 Wear-levelling should be handled by the flash memory controller, and you shouldn't need to worry about it.
