Portable, hands free DGPS system

Hi all, I am looking for a portable, hands free (D)GPS system to mount on bikers and pedestrians with high refresh rates. The more compact, the better. We would like to record cyclists’ and pedestrians’ positions in real world with the least inconvenience possible. Currently we have an Ublox evaluation kit with an accuracy of 1 m, we would like to improve that. A system with RTK and GPS combined is what would be the best option in our opinion, but we are open to ideas. If it can record on its own, that is nice, but wifi or portable recorder is also fine (like a rpi). The budget is quite flexible, we would like to see the options first.
