Inertial Navigation - Technology MSA purchased Acceleron Technologies, LLC,
in early 2007 Founded by geophysicists at LLNL Held four US patents claiming frequent zero
velocity updates (ZUPT) using foot-mounted IMUs5724265 - Foot mounted accelerometers & gyroscopes5899963 - Added processing6122960 - Added wireless connectivity6305221 - Added magnetometers
Conducted many individual tests

Inertial Navigation - Progress Conducted a comprehensive series of tests
Ten (10) different walkers Ten (10) different sensors Five (5) different facilities Two (2) different courses at each facility
Series of tests included many activity types Walking Running Crawling Climbing Rappelling Jumping / falling Riding an elevator Riding an escalator

Future Development MSA has decades of experience developing
and manufacturing rugged and reliable products for the fire service
We are applying this knowledge to create a robust firefighter location system around our inertial navigation core

Conclusion MSA has evaluated many indoor location
technologies MSA believes inertial navigation will provide
the best solution in the least amount of time Test results have shown that a robust,
reliable product is possible in the near future MSA is excited about the opportunity to
provide first responders this potentially life saving technology
