3.6 Vehicle velocity input
The AsteRx SBi3 can receive vehicle velocity information and use it as part of the integrated
position. The use of the vehicle velocity it is not required for the function of the device.
Vehicle velocity input improves the dead reckoning performance and heading performance
in single antenna.
I t is important to highlight that the contribution of the vehicle velocity
input to the AsteRx SBi3 performance is function of the velocity computation accuracy and
latency. The expected velocity input is an already computed vehicle speed, NMEA VSM
stream, and not raw sensor data. For the communication details please look into the AsteRx
SBi3 Firmware Reference Guide.
