Problems solved by technology

At present, people's daily positioning mainly relies on foreign satellite GPS positioning. Once foreign countries stop business leasing or receive other interference, they cannot know the specific positioning. At the same time, satellite GPS positioning mainly relies on radio waves to transmit signals, which is vulnerable to various factors. Interference, so after the GPS fails, a positioning method that can assist in positioning is needed

Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are explanations of the present invention and the present invention is not limited to the following examples.

[0030] Such as figure 1 As shown, a device for quickly measuring the height of the sun includes a base 1, an astronomical platform 2, a U-shaped bracket 3, a mid-slit projection plate 4, a reflector 5, and an AHRS module 6. The lower end of the U-shaped bracket 3 is rotated on the base 1 On the upper side, the astronomical platform 2 is fixed on the rotating shaft 7, and the two ends of the rotating shaft 7 are rotated and installed at both ends of the upper side of the U-shaped bracket 3. The AHRS module 6 is horizontally arranged and fixed in the middle of the astronomical platform 2, and the projection plate 4 and the reflector in the middle seam 5 are parallel to each other and vertically fixed on the two ends o...

Abstract

The invention discloses a device for quickly measuring the height of the sun and a positioning method based on the device. The orientation of the sun can be quickly found through the projection plate in the middle slot, and the concave mirror of the reflector is aligned with the projection center by rotating the astronomical platform. At this time And the flip angle of the astronomical platform can be directly measured by the AHRS module, which is easy to operate and easy to use; at the same time, the navigation positioning can be carried out by combining the sun height with the mapping method. When the GPS is interfered or cannot be used in other cases, it can be used Solar altimetry aids in positioning.

Description

technical field [0001] The invention relates to a device for quickly measuring the height of the sun and a positioning method based on the device, belonging to the field of navigation positioning. Background technique [0002] The sun altitude angle is referred to as the sun altitude (actually an angle). For a certain place on the earth, the solar altitude angle refers to the angle between the incident direction of sunlight and the ground plane. Professionally speaking, the solar altitude angle refers to the surface section of a certain place where the sun's rays pass through the place and connect to the center of the earth. angle. The altitude angle of the sun is referred to as the altitude angle. When the sun's altitude angle is 90°, the solar radiation intensity is the largest at this time; when the sun obliquely hits the ground, the solar radiation intensity is small. The height of the sun is of great significance in navigation or other positioning. People can calcula...
