Twin IMU-HSGPS Integration for Pedestrian Navigation
Pedestrian navigation includes locating individuals of interest, including citizens, police officers, fire fighters, search and rescue personnel, and cell phone users. GPS can typically provide users with this ability. In signal degraded areas such as in the indoors, underground parkades and urban canyons, GPS must be integrated with additional sensors to provide availability to users with a re...
متن کاملMultiple IMU Integration for Vehicular Navigation
One of the most widespread applications of the Global Positioning System (GPS) is vehicular navigation. Improving the navigation accuracy continues to be a focus of research, commonly answered by the use of additional sensors. A sensor commonly fused with GPS is the inertial measurement unit (IMU). Due to the fact that the requirements of commercial systems are low cost, small size, and power c...
متن کامل1G2A IMU\GPS Integration Algorithm for Land Vehicle Navigation
A general decline in the cost, size, and power requirements of electronics is accelerating the adoption of integrated GPS/INS technologies in consumer applications such Land Vehicle Navigation. Researchers have looking for ways to eliminate additional components from product designs. One possibility is to drop one or more of the relatively expensive gyroscopes from microelectromechanical system...
متن کاملPerformance evaluation of Cubature Kalman filter in a GPS/IMU tightly-coupled navigation system
In a GPS/IMU tightly-coupled navigation system, the extended Kalman filter (EKF) is widely used to estimate the navigation states, due to its simpler implementation and lower computational load. However, the EKF is a first order approximation to the nonlinear system. When the nonlinearity of the system is high, the negligibility in higher order terms of the nonlinear system will degrade the est...
متن کاملAssessment of GPS/MEMS-IMU Integration Performance in Ski Racing
This paper describes an experiment involving a professional downhill skier equipped with GPS and MEMS-IMU, as well as a triad of magnetometers and a tactical-grade inertial unit. The experiment illustrates the navigation performance of GPS/MEMS integration compared to high-quality GPS/INS integration challenged by the environmental conditions and dynamics of ski-racing. The MEMS sensors’ output...
