Patent ID: 8041535

Claim:
A targeting system for tracking angle changes from a reference azimuth, comprising: a mount, said mount configured for supporting a sighting scope; an angle encoder, said angle encoder being integrated with said mount, the angle encoder configured for tracking angle changes from the reference azimuth; and an inertial sensor, said inertial sensor being integrated with said mount, said inertial sensor being communicatively coupled with said angle encoder, the inertial sensor configured for tracking angle changes from the reference azimuth, wherein, when the target system is supported by a support surface and is fixed at a first position on said support surface, the system is configured for determining the reference azimuth, the system being further configured for selectively relying on angle change tracking provided by one of: the angle encoder and the inertial sensor, such that when the targeting system is fixed at a same position on said support surface as when said reference azimuth was determined, utilizing the angle change tracking provided by the angle encoder instead of the angle change tracking provided by the inertial sensor.
