Pressing Start will display the starting position (green circle) and 3 path traces:
Purple – DOM DST and GPS Fusion
Blue – GPS only
Black – DOM DST inertial tracking only.
Figure – Path shown the map
When tracking outdoors only, for the most part, the blue color DOM-GPS Fusion path will align with the
purple color GPS path. The DOM-GPS path tracks to step resolution and hence you will be able to track
movement to finer resolution. When moving from outdoors to indoors, the purple color DOM-GPS path
will continue to track accurately while the blue color GPS only path will have large errors.
In this DOM DST Evaluation kit release, the DOM-DST Inertial tracking path assumes initial direction of
travel to be North. Hence DOM-DST Inertial path will have a rotation error and scaling error. Contact
our FAE team at [email protected] if your application will never have GPS access. We
can tailor the inertial tracking to work within your application.
