Inertial measurement unit using rotatable MEMS sensors

An inertial measurement unit comprising;

• a base having at least one surface;
• at least two rotatable MEM stages disposed on the at least one surface, each of the at least two MEM stages being independently rotatable about a rotational axis lying substantially along a normal axis to the surface upon which the rotatable MEM stage is disposed;
• at least two MEM inertial sense elements, each having a sense axis, the at least two MEM inertial sense elements being disposed on the at least two MEM rotatable stages, wherein the sense axes of the at least two MEM inertial sense elements, are substantially perpendicular to the rotational axis of the rotatable MEM stage, upon which the MEM inertial sense element is disposed;
• means for independently rotating each of the at least two rotatable MEM stages;
• and,
• means for electrically accessing the at least two MEM inertial sense elements at, at least two angular positions of each of the at least two rotatable MEM stages.
