I have recently been closely cooperating with the develpopers of the Firetail software - a program to visualize tracking and sensor data for movement ecology - to get them to support acceleration data from our VECTRONIC Aerospace GPS collars.
It is simply amazing to be able to see and interactively explore tracking and continuous acceleration data at 8Hz over 1.5 years.
They also support acceleration data from a few other brands:
Firetail even has an option for non-supervised segmentation of the different acceleration signatures (corresponding to different behaviours).
You can get a test license to try it out yourselves:
