Embodiment Construction

[0055] figure 1 A flow chart of a method for detecting the heading angle of an aircraft is shown in a specific embodiment of the present invention. The technical solution of the present invention calibrates the original heading angle measured by the RTK dual antenna and obtains the aircraft heading angle, wherein the RTK dual antenna realizes the coincidence of the phase center and the geometric center through a completely symmetrical antenna structure, so as to reduce the antenna pair error Impact.

[0056]In the present invention, first enter step S101, encode the RTK dual antenna into the first RTK antenna and the second RTK antenna, define the direction in which the first RTK antenna points to the second RTK antenna as the antenna vector, and define the tail pointing direction The direction of the nose is the direction of the fuselage. Specifically, the RTK dual antennas are used to cooperate with receiving satellite positioning or navigation signals. The present invent...

Abstract

The invention provides a method for detecting the course angle of an aircraft. The method allows the course angle of the aircraft to be obtained through calibrating an original course angle measured by dual RTK antennas, and comprises the following steps: 1, encoding the dual RTK antenna as a first RTK antenna and a second RTK antenna, defining a direction of the first RTK antenna pointing to the second RTK antenna as an antenna vector, and defining a direction of a tail pointing to a head as a fuselage direction; 2, taking an included angle between the antenna vector and the fuselage direction as correction angle data; 3, acquiring the original course angle of the aircraft through cooperating the dual RTK antennas with an RTK module; and 4, correcting the original course angle by the correction angle data, and converting the corrected original course angle into the course angle of the aircraft. The method has the advantages of realization of the detection and the correction of the course angle of the aircraft, ensuring of the course correctness of the aircraft, high precision and good real-time performance.

Description

technical field [0001] The invention belongs to the technical field of navigation and positioning, and in particular relates to a method for detecting a heading angle of an aircraft and a detection device thereof. Background technique [0002] With the rapid development of navigation and positioning technology, the demand for fast and high-precision location information is also increasing. RTK (Real-time kinematic) carrier phase difference technology, that is, a real-time dynamic positioning technology based on carrier phase observations, can provide real-time three-dimensional positioning results of the station in the specified coordinate system, which not only has high precision, but also has strong Anti-electromagnetic interference capability. Bringing RTK technology into the field of drones can improve positioning accuracy and reduce flight errors for drones and other aircraft. [0003] The dual antennas can provide a high-precision heading, so that the UAV and other a...
