A method of registering the systematic attitude errors and measurement elevation error of Airborne Radar is proposed in this *** airborne radar,the principal sources of the error are the attitude errors,including pitching,yaw,roll and the elevation error in the measurement of *** for the azimuth error,it is generally tiny compared with other angle *** the effect of range bias is not as significant as angle ***,in this paper we construct an alignment model without considering the range error and azimuth *** on this hypothesis,a pairwise sensor alignment algorithm in Earth-Centered Earth-Fixed （ECEF） coordinates is *** results reveal that our proposed algorithm has great accuracy and convergence velocity.

第三届中国卫星导航学术年会

GNSS/INS integrated navigation systems can be used as a positioning and orientation system （POS） to provide high precision attitude and position in Mobile Mapping Systems （MMS）,. The attitude （roll, pitch, and yaw） errors will diverge with time when the vehicle is moving with low dynamics （e.g. no changes of attitude and acceleration）, which makes the attitude estimation weakly observable. This is one dominant error source in the POS applications. It can be mitigated by making corresponding vehicle maneuvers to make the navigation states observable. In this paper, the influences of different vehicle maneuvers to the attitude estimation errors are analyzed through simulation method. Results have shown that the motion with time-varying angular rates or accelerations can enhance the yaw estimation, while uniform circular motion is not useful for yaw error estimation. The outcomes of this paper can provide reference to the motion design of the MMS vehicles to maintain the attitude accuracy of the POS.
