8. Dead Reckoning
Although Dead Reckoning Functionality is still pending to be implemented at the time
of issue of the present document, this is planned to be functional in the coming
months.
Dead Reckoning is the process of calculating one's current position by using a
previously determined position, or fix, and advancing that position based upon known
or estimated speeds over elapsed time and course.
The Dead Reckoning will use some CAN information from vehicle in order to support
the necessary calculations such as inertial’s data, vehicle speed, etc.
The Dead Reckoning Functionality will start working automatically when coverage
level goes below a specific threshold. This provides a way to estimate the GNSS
position of the vehicles when there isn’t good GNSS coverage.
