Embodiment Construction
[0088] Such as Figure 3-4 As shown, the embodiment provides a navigation method of an adaptive UKF algorithm,
[0089] Step 1: Collect the raw data of the inertial sensor, including the three-axis acceleration value output by the accelerometer and the three-axis angular rate value output by the gyroscope;
[0090] Step 2: update the positioning information of the inertial navigation system, and calculate the eastward, northward, celestial velocity, pitch angle, and roll of the carrier in the northeast sky coordinate system according to the acceleration value and angular rate value output by the inertial measurement device and the initial value of the system state Angle, heading angle, and then calculate the longitude, latitude and height information;
[0091] Step 3: Search and collect GPS positioning information, including the current carrier latitude and longitude, altitude, and three-way speed in the northeast sky, and judge the reliability of the satellite signal accordi...
