Self-localization is a precondition for many wireless sensor network (WSN) applications. To obtain a more accurate and robust localization, an improved quadrilateral localization algorithm is proposed. Considering a real environment, a flip ambiguity detection criterion is adopted into trilateration localization. And for the propose of avoiding intense fluctuation and error propagation of localization...
Advanced robot's navigation system based on GPS/INS is established in order to meet its working surroundings and taskpsilas demand. Centralized open-loop Kalman filter is applied in the navigation system. GPS/INS devices' output difference is the filter's input. The position-velocity integrated measurement equation is deduced based on the robotpsilas locomotion performance and measurement demand....
