Background :
Background Scuba divers do not have a navigation system
No GPS
Existing solutions have holes Goals Give divers a better and safer navigation option
Create an INS meant for high pressure
Constraints and Problems :
Constraints and Problems Must operate in at least 5 atmospheres
Must be very sensitive
Must be small
Design and Considerations :
Design and Considerations Cantilever beam
Filled with fluid
Fluid will affect damping
Still under consideration
Calculating damping with fluid
Will Fluid allow required sensitivity
(possibly 500mV/g)
