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 present disclosure relates to a navigation device and method for unmanned equipment and the unmanned equipment. The unmanned equipment is provided with a first antenna and a second antenna, and the device includes: a first receiver, used to couple with the first antenna, and determine the first position of the first antenna according to the first radio frequency signal sent by the first antenna information and first speed information; the second receiver is used for coupling with the second antenna, and determines the second position information of the second antenna according to the second radio frequency signal sent by the second antenna; the inertial measurement unit is used for collecting acceleration information and Angular velocity information; the processor component is used to determine the current course angle information of the unmanned device according to the first position information and the second position information, and according to the current course angle information, the first position information, the first speed information, the acceleration information and Angular velocity information, to determine the target navigation information of the unmanned equipment. As a result, the precision and accuracy of target navigation information can be improved, and accurate and effective navigation information can be 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...
