Abstract
Land vehicle navigation system technology is a fastest growing section of focus for research recently due to its potential for both consumer and business vehicle markets. Global Positioning System (GPS) is a conventional choice in such systems. However, GPS alone is incapable of providing continuous and reliable positioning, because of its inherent dependency on external signals. The availability of low cost MEMS inertial sensors is now making it feasible to use Inertial Navigation System (INS) in conjunction with GPS to fulfill the demands of such systems. This paper therefore proposes an INS/GPS scheme which uses two Kalman Filters to filter and estimate the navigation parameters. The simulation based on experiment data and performance analysis are also present to show the positioning capability of the GPS/INS integrated systems for land vehicle navigation system and investigates on methods to improve its performance.
