Build GPS board plugable into Lemming board with surface mount antenna

Find a GPS antenna we can surface mount on a small PCB, with GPS chips to make a small GPS board integrated to the next version of the lemming board. This is to replace the poor quality Libelium GPS solution.

Requirement: no coaxial cable in between antenna and chip. Maybe commercial version exist (see Sparkfun or others) we could simply use. To be reviewed
