In GNSS/INS navigation integrated systems, the selection of inertial sensors is a factor which can impact their system performances implicitly. Unfortunately, the research of the relationship between the inertial sensor errors and the navigation performances is not sufficient yet. In this case, the mathematical relationship between the sensor quality and the INS (Inertial Navigation System) performance...
Most global navigation satellite system (GNSS) receivers cannot work in high dynamic scenarios because of poor navigation satellite acquisition in these environments. Hence, inertial navigation system (INS) is used to aid the GNSS signal acquisition and improve the acquisition capability of the receivers. In this paper, an ultra-tight integration system using the low-cost IMU is proposed to achieve...
In this paper, the sufficient and necessary conditions that a triangular subnorm M is (α, T)-cross-migrative are given out, where T stands for any of the three prototype triangular norms, that is, is ε {Tp, Tm, Tl}, M is a triangular subnorm with a continuously additive generator. By comparison with results of the (a, T)-cross-migrativity of triangular norms obtained by Fodor, it is in some sense...
In this paper, a new kind of fuzzy relation equations (FREs for short) A0R* x = b is first introduced, and then the problem of solving solution to the FREs is discussed, where A is an mtimesn matrix, x and b are an n and an m dimension column vectors, respectively. More specifically, its solvability and unique solvability are investigated, the corresponding necessary and sufficient conditions are...
