Abstract
Global Positioning System (GPS) is the most common way for navigation. However,
it needs a direct connection to a satellite, which is not applicable inside
buildings. This could be crucial in case of firefighting or catastrophes. Thus, a
backup aiding system is needed to do this function when GPS is either unreliable
or unavailable. Microelectormechanical System (MEMS) sensor-based can provide
navigation accurately. The overall Navigation system will be Aided MEMSbased
inertial navigation that uses Dead Reckoning (DR) technique to calculate
current position and velocity relative to an initial reference frame (position, velocity).
This backup system is called Inertia Measurement Unit (IMU) and it is
consist of an accelerometer, a gyroscope and a magnetometer.MEMS-based magnetometers
score high in miniaturization, compared to other existing technologies
and have high potential to be integrated with CMOS. Thus, they provide a low
cost integrated electronic compass system.
