Not sure if the question has been approached correctly, the question is really will the operating system support GPS modules. As with most computer hardware issues usually resulting from software issues, or the operating system not correctly being able to recognise the hardware and its functions, not usually a problem with the computer.
Most USB GPS modules have a simple USB-Serial interface which is supported by the Pi. Then you just need to install GPS software, a a simple apt-get install gpsd. Hey presto, most USB GPS stuff will just work.
