Abstract: A resonator includes a first sub-resonator and a plurality of second sub-resonators. The first sub-resonator in vibration deforms in at least two non-parallel directions. The first sub-resonator is connected to the second sub-resonators in all the at least two non-parallel directions, and deformations in all the at least two non-parallel directions couple the first sub-resonator to the second sub-resonators. Then, the resonator can balance a Q value and Rm, and can have a higher Q value and lower Rm.

Abstract: A method includes the following steps: obtaining a first status of an object, where the first status includes a first position and a first pose; obtaining a second status of the object through inertial navigation by using the first status as a start point, where the second status includes a second position and a second pose; obtaining a third pose of the object through initial alignment; and providing inertial navigation for the object by using the third pose and the second position as a start point. A positioning and orientation apparatus and a positioning and orientation device are further provided. The second pose is replaced with the third pose obtained through initial alignment.
