- The attitude information is one of the most important
parameters in flight control systems. This paper describes an
attitude measurement system based on a MEMS multi-sensor. The
data from 3-axis MEMS accelerators and 3-axis MEMS gyros is used
to determine the pitch angle and the roll angle of the air vehicle using
an extended Kalman filter (EKF) equation deduced from the
direction cosine matrix. An expert system was designed to estimate
the vehicle motion to adjust the measurement noise matrix of the
extended Kalman filter equation so that the system can be used in
dynamic as well as static environments. The measured airspeed and
altitude are also used to revise the pitch angle. The heading is
determined from GPS information. Test results compare well with
an imported commercial autopilot in a static test with less accurate
results in a dynamic test.

Description: 多天线姿态确定工具箱，包括星历读取、单点定位、差分定位、坐标转换、定姿等-In this paper a MATLAB toolbox for determining the attitude of a rigid platform by means of multiple non-dedicated antennas using global positioning system is presented. The programs embedded in this toolbox cover the RINEX data analysis, single point positioning, differential positioning, coordinate conversion, attitude determination, and other auxiliary functions. After forming the baselines through double-differenced (carrier phase smoothed) code observables, the attitude parameters are obtained by applying the direct attitude computation and the least squares attitude estimation. The theoretical background is summarized, and some hints regarding the software implementation are given in the paper. Moreover, improvements yielding an expanded functionality are proposed.
