What’s the PayoffCommon Guidance provides:
common performances across multiple platformscost reduction
More accuracy has a cost “ripple” effectfewer firingssmaller footprint/field of viewpositive benefit on logistics

Program Output• Common Interface Control Document for
compatibility across multitude of platforms• Common Performance Specification for consistent
output signals• Two qualified suppliers producing interchangeable
devices
Provide Common MEMS IMU/DIGNUfor 90% of all DoD Applications

Summary
• Honeywell and L3 are committed to producing MEMS IMUs for future DoDsystems
• Program will develop two contractors that can provide MEMS IMUs & DIGNUsfor the military at program completion
• Utilizing ManTech dollars allows program to achieve aggressive S & T goals• Next public presentation of the ICD and performance specification to potential
end users will occur at the MEMS IMU Industry Day targeted for September 2004
