 Software solution for DA2 in running / jogging in urban canyon

Hello,

I have a Trimble DA2 antenna (with RTK subscription).

My use case is somewhat specific as the goal is to get the precise (submetric) trajectory of a person running/jogging in dense urban canyon. The antenna is mounted on top of a pole, threaded onto the Trimble backpack. Still, this means the application is definitely not static, there is some accelerations (and rotations).

I'm looking for a software solution that would allow me :
- to correctly use the antenna capabilites ; most notably the ones that ought to be of importance for such a use case : multi-constellations, multi-band, high frequency update rate (>1 Hz, maybe 5 Hz)
- to NOT be overtuned towards static use / implicitly making internal hypothesis somewhere that the user is static (or even at straight constant velocity)

I have no idea what kind of software solution could be considered. (We have for example tried TMM and results are unusable as soon as the user starts moving, but it looks like TMM is highly tuned for static uses - fine, that just means we need another solution).

Note this doesn't have to be real-time. If the suggestion solution is only available by post-processing raw antenna information, that is perfectly fine.

What would be your suggestions ?

Thanks for your help
