Embodiment Construction
[0078] The present invention will be described in further detail below in conjunction with the examples, but the embodiments of the present invention are not limited thereto.
[0079] The agricultural machinery used in this embodiment is a Kubota rice transplanter, on which a navigation sensor combination, a steering control system and a portable computer are loaded, and the portable computer is connected with the navigation sensor combination and the steering control system through a USB-RS232 data transmission line to form a navigation control system. The system, the principle structure is shown in Figure 8.
[0080] The navigation sensor portfolio includes pseudorange differential GPS, electronic compass and micromachined gyroscope. The pseudo-range differential GPS can collect the positioning coordinates of the rice transplanter in the WGS-84 coordinate system as preliminary positioning information; the electronic compass measures its heading angle information (the north d...
