Problems solved by technology

[0003] In the navigation technology, the inertial navigation technology has strong autonomy and can provide continuous navigation information, but the navigation error accumulates over time.
The error of satellite navigation technology does not accumulate over time, and the long-term accuracy is high. However, it is easily affected by random factors such as building occlusion and electromagnetic interference.

Abstract

The invention relates to a navigation device and a method for unmanned equipment and the unmanned equipment. The unmanned equipment is provided with a first antenna and a second antenna. The device comprises a first receiver used for being coupled with the first antenna and determining first position information and first speed information of the first antenna according to a first radio frequencysignal sent by the first antenna; a second receiver used for being coupled with a second antenna and determining second position information of the second antenna according to a second radio frequencysignal sent by the second antenna; an inertia measurement unit used for collecting acceleration information and angular velocity information; and a processor assembly used for determining current course angle information of the unmanned equipment according to the first position information and the second position information, and determining target navigation information of the unmanned equipmentaccording to the current course angle information, the first position information, the first speed information, the acceleration information and the angular speed information. Therefore, the precision and the accuracy of the target navigation information are improved, and accurate and effective navigation information is provided for unmanned equipment.

Description

technical field [0001] The present disclosure relates to the field of navigation, and in particular, relates to a navigation device and method for unmanned equipment and unmanned equipment. Background technique [0002] Unmanned equipment, such as unmanned delivery vehicles, is more and more widely used in distribution, logistics and other fields. Unmanned delivery vehicles rely on the support of high-precision navigation technology. Only accurate navigation information can ensure the safe and accurate delivery of unmanned delivery vehicles and provide users with high-quality delivery services. [0003] Among navigation technologies, inertial navigation technology has strong autonomy and can provide continuous navigation information, but navigation errors accumulate over time. The error of satellite navigation technology does not accumulate over time, and the long-term accuracy is high. However, it is easily affected by random factors such as building occlusion and electrom...
