State estimation on small embedded navigation boards is usually a software problem: the filter runs on the same core doing everything else, and update rate gets traded against power budget and other real-time tasks. Dedicated hardware acceleration for the filter update step is a meaningful shift if the accelerator is flexible enough to support a real error-state formulation rather than a fixed, simplified filter.
For small AUV and UAV navigation computers, offloading the fusion update from the main core could free up budget for higher-rate IMU sampling or additional aiding sensors without a power penalty — relevant to the kind of embedded navigation work covered in the GNSS/INS navigation computer project.
The details that matter here are the ones vendors tend to leave out of announcements: which filter structures the accelerator actually supports, and what the real achievable update rate is under load, not just in a datasheet best case.
