Abstract:
A method for positioning and attitude determination, applied to the field of positioning and attitude determination. The method comprises the following steps: obtaining a first state of an object, the first state comprising a first position and a first attitude (101); obtaining a second state of the object by means of inertial navigation by taking the first state as a starting point, the second state comprising a second position and a second attitude (102); obtaining a third attitude of the object by means of initial alignment (103); and providing the inertial navigation for the object by taking the third attitude and the second position as starting points (104). The present application further relates to an apparatus for positioning and attitude determination, and a device (511) for positioning and attitude determination. By replacing the second attitude with the third attitude obtained by means of the initial alignment, the accuracy of positioning and attitude determination can be improved.
