According to the present embodiment, the location information providing device 90 may be equipped with a Global Navigation Satellite System (GNSS), and in particular, an antenna of the GNSS may be mounted on the mounting bracket 20.

As shown in Fig. 4, the GNSS antenna is circular when viewed from the top and is rounded downward from the top. Hereinafter, in the present embodiment, the description will be made on the premise that a GNSS round antenna is mounted on the mounting bracket 20.

The mounting bracket 20 is provided with a mounting portion 21 bent downward to mount the antenna, and a connection portion 22 to which a first bracket 30 to be described later is coupled to both ends of the mounting portion 21 .

The first bracket 30 is rotatable with respect to a predetermined first rotation shaft 61 and supports the mounting bracket 20. The first rotation axis 61 is an axis perpendicular to the Z axis vertically supporting the center of the main body 10. For convenience of explanation, the first rotation axis 61 is defined as a Y axis perpendicular to the Z axis. The first rotation shaft 61 is a shaft connecting both ends of the first bracket 30, and the first bracket 30 rotates about the first rotation shaft 61.

The first bracket includes vertical frames 31 extending upward from both ends of the seating bracket, and a connection frame 32 connecting the vertical frames 31 to each other. The vertical frame 31 extends upward from the connection part 22, and the connection frame 32 connects upper ends of the vertical frames 31 facing each other.

The second bracket 40 is rotatable about a second rotation shaft 62 perpendicular to the first rotation shaft 61. Both ends of the second bracket 40 are coupled to the first bracket 30, respectively. According to this embodiment, the second rotation axis 62 is an axis perpendicular to the Z axis and the Y axis, and for convenience of explanation, the second rotation axis 62 is defined as the X axis.

Accordingly, the first rotation shaft 61 and the second rotation shaft 62 become axes with respect to the XY plane. The second bracket 40 is formed in a schematic “C” shape, and both ends thereof are connected to the first rotation shaft 61 to which the first bracket 30 is rotatably coupled.

In this way, since the buoy device 200 having a posture stabilizing device of the location information providing device according to the present invention, and a posture stabilizing device 100 for stabilizing the posture of the location information providing device 90 are provided inside the main body 10 , By maintaining the posture of the location information providing device 90 in a static posture, location data of the buoy device 200 is more accurately acquired, and accurate location data can be provided to the outside.

In addition, the first and second outer frames prevent the tension of the connection line from being directly transmitted to the main body 10, so that the posture of the main body 10 is prevented from being changed by the tension. Therefore, by stably maintaining the posture of the main body 10, it is possible to more accurately obtain location information.

The present invention has been described above, but the technical scope of the present invention is not limited to the contents described in the above-described embodiment, and the equivalent configuration modified or changed by a person having ordinary skill in the relevant technical field is the technical scope of the present invention. It is clear that it does not go beyond the scope of thought.
