The importance of
security precautions has been increased as a consequence of raised terrorist
incidents. Terrorist acts that move into the city from country sides have made
tracking of security and military personnel more important. GPS signals,
densely utilized for this tracking, pose a problem in signal blockage situation
and GPS-denied environments. The main goal of this research is that to develop
a practical positioning system for walking military personnel in GPS denied
environments. The system is very useful for GPS signal blockage environments,
such as tunnels, thick-walled structures and dense high rise buildings, etc.
Proposed system contains a 6-degree of freedom
(DOF) inertial measurement unit (IMU) and digital compass attached to the
military personnel’s shoe. Tri-axis accelerometer and gyroscope measurements
are obtained by IMU. These measurements are applied to fuzzy logic algorithms
and total displacement for each step is calculated. Digital compass is utilized
to determine direction of personnel. Thus, current location has been estimated
with the known starting point.
