Abstract
Inertial measurement unit apparatus for use with guidance systems are disclosed herein. An example guidance system includes an inertial measurement unit removably coupled in a cavity of a guidance wafer via an access port of the guidance wafer defining a port axis that is non-parallel relative to a longitudinal axis of the guidance wafer.

14. A method of replacing a guidance system comprising:
-
opening an access port to a body of a guidance wafer, the access port to enable access to a cavity of the guidance wafer, the access port to provide an opening having an axis substantially perpendicular relative to a longitudinal axis of the guidance wafer; and removing or inserting an inertial measurement unit relative to the cavity of the guidance wafer via the access port. - View Dependent Claims (15, 16, 17, 18)

21. A guidance system comprising:
-
a guidance wafer having a first side coupled to a first wafer and a second side coupled to a second wafer, the guidance wafer having a longitudinal axis coaxially aligned with respective longitudinal axes of the first and second wafers when the guidance wafer is coupled to the first and second wafers; an access port formed in a body of the guidance wafer, the access port defining an opening to enable access to a cavity of the guidance wafer, the access port or the opening defining an axis that is substantially perpendicular to the longitudinal axis of the guidance wafer; a panel removably coupled to the body of the guidance wafer, the panel to expose the opening of the access port when the panel is removed from the body; and an inertial measurement unit removably coupled in the cavity of the guidance wafer, the inertial measurement unit to be inserted or removed from the cavity via the opening of the access port when the panel is removed from the body of the guidance wafer. - View Dependent Claims (22)
