Inertial navigation module

This paper presents low cost Inertial Navigation Module, using MEMS sensor and an simple onboard microcontroller data processing (Kalman filters, basic interpretation for data). GPS navigation solutions are investigated, but they encounter big issues in indoor environment. The basic problem is the weak signal power received from satellite in indoor location and therefore the increased error for position. Using another technique and sensor add more precision. MEMS based techniques are promising ones. Using an accelerometer and a digital compass allows the determination of additional parameters that can lead to determine the position or improve existing location. The components used are the usual, available at any specialty store and precision obtained using a minimal data processing software is encouraging. Research direction to follow is to process the data obtained for growth and greater accuracy
