In some GPS failure conditions, positioning for mobile target is difficult. This paper proposed a new method based on INS/UWB for attitude angle and position synchronous tracking of indoor carrier. Firstly, error model of INS/UWB integrated system is built, including error equation of INS and UWB. And combined filtering model of INS/UWB is researched. Simulation results show that the two subsys...

In order to improve the performance of an inertial navigation system, many aiding sensors can be used. Among these aiding sensors, a vision sensor is of particular note due to its benefits in terms of weight, cost, and power consumption. This paper proposes an inertial and vision integrated navigation method for poor vision navigation environments. The proposed method uses focal plane measureme...

Abstract We present an alternative technique for estimating the response of a cold atom interferometer (CAI). Using data from conventional inertial measurement unit (IMU) and common strapdown terminology, position wave packet is tracked in newly introduced sensor frame, enabling hybridization both systems terms acceleration angular rate measurements. The frame allows easier mathematica...
