Abstract
Techniques for vehicular navigation include determining a first attitude of a vehicle with respect to a reference frame at a first epoch, the determined first attitude including a determined first roll angle; computing an attitude of the INS at a second epoch that is subsequent to the first epoch; determining a second attitude of the vehicle at the second epoch; updating the determined second attitude of the vehicle, based on a determination that an absolute change in a yaw angle of the vehicle between the first epoch and the second epoch is less than a predetermined threshold, by setting a roll angle of the determined second attitude of the vehicle to equal the determined first roll angle; and based on the updated second attitude of the vehicle, determining an updated attitude of the INS. Applications relating to road vehicular (e.g., automobile) use are described.
