1. A navigation system, comprising:
a first navigation subsystem comprising an inertial measurement unit (IMU), the first navigation subsystem configured to provide a first signal; and
a second navigation subsystem configured to provide a second signal,
wherein the navigation system is configured to provide a pose signal based on the first signal of the first navigation subsystem and the second signal of the second navigation subsystem, the pose signal having a lower latency than the second signal of the second navigation subsystem.
