Abstract
Many possible Autonomous Underwater Vehicle (AUV)
missions require a high degree of navigutional accuracy.
The Global Positioning System (GPS) is capable
of providing this accuracy. However, intermittent reception
caused by either wave action or deliberate submergence
will cause the loss of GPS position fix information
for periods extending from several seconds to minutes.
The SANS system is designed to demonstrate the feasibility
of using a low-cost strapped-clown Inertial Measurement
Unit (IMU) to navigate between GPS fixes. It
is anticipated that navigational accuracy comparable to
GPS is possible between fixes.
