BATCHELOR ANDREW / WATSON DOUGLAS

A computer-implemented method of determining a position of a vehicle within a transport network comprises obtaining track geometry data indicating track geometry of at least a part of the transport network; receiving first sensor data from an inertial measurement unit mounted to the vehicle; executing a Bayesian estimation filter algorithm to predict a position of the vehicle, wherein the Bayesian estimation filter algorithm comprises a process model, the process model comprising a strapdown inertial navigation algorithm, and wherein the strapdown inertial navigation algorithm generates data indicative of the predicted position of the vehicle based at least upon the first sensor data and the track geometry data such that the predicted position of the vehicle lies on a track defined by the track geometry data; receiving second sensor data from a sensor other than an inertial measurement unit, wherein the sensor is mounted to the vehicle; executing the Bayesian estimation filter algorithm to update the predicted position of the vehicle based at least upon the second sensor data; and generating an output indicative of a position of the vehicle within the transport network based upon at least one of the predicted position of the vehicle and the updated predicted position of the vehicle.
