Abstract
Description
[Technical Field]
[0001] The present invention relates to a navigation communication device, and more particularly to a communication device that is lightweight, compact, and has power-saving properties, and prevents interference with navigation. [Background technology]
[0002] Currently, unmanned aerial vehicles (UAVs), unmanned ships, unmanned vehicles, etc. are gradually becoming indispensable unmanned carriers on the battlefield. For example, the use of small UAVs on the battlefield has already become commonplace, and this threat has only increased with technological advances. Summary of the Invention [Problem to be solved by the invention]
[0003] A "jamming gun" is a battery-powered electromagnetic pulse weapon that hangs from the operator's shoulder and fires directional radio waves at flying targets, similar to an infantry rifle. While it is not a rifle or a gun that fires live ammunition, its operation and appearance are similar to those of a typical infantry rifle, as reflected in its name. A jamming gun fires a single electromagnetic pulse, interfering with the navigation and transmission channels that control the drone, terminating communication between the drone and its operator and causing it to lose control and crash.
[0004] Currently, unmanned carriers are being developed to be lighter, and when advanced anti-interference equipment is used on small and lightweight unmanned carriers, it is difficult to use it due to its bulk and weight. For this reason, countries around the world are currently focusing on deploying jamming guns, but it is difficult to prevent interference on small and lightweight unmanned carriers, and they lose their functionality, so there is room for improvement.
[0005] Therefore, the inventors of the present invention believed that the above drawbacks could be improved, and after extensive research, they came up with the present invention, which effectively improves the above issues through rational design.
[0006] The present invention has been made in view of the above circumstances, and aims to solve the above problems. That is, the purpose of the present invention is to provide a communication device that prevents interference with navigation, which improves the problems of the prior art and promotes the effects of weight reduction, size reduction, and power saving. [Means for solving the problem]
[0007] In order to achieve the above object, a communication device for preventing interference with navigation, which is one aspect of the present invention, is installed on an unmanned vehicle. The communication device that prevents interference with navigation is composed of MEMS and a 9-axis sensor including a 3-axis gyroscope, a 3-axis magnetometer, and a 3-axis gravity accelerometer. An FM video modulator connected to the camera, a digital narrowband communication device electrically connected to the 9-axis sensor and the FM image modulator and capable of two-way communication and control of the channel of the FM image modulator; It is equipped with: [Effects of the Invention]
[0008] The present invention is configured as described above and therefore has the following advantages. 1. The communication device for preventing interference with navigation according to the present invention is a combination of (A) a 9-axis MEMS sensor, (B) an FM image modulator, and (C) a digital narrowband communication device, so that (A) + (B) + (C) are configured to complement each other, promoting the effects of weight reduction, miniaturization, and power saving. Second, the communication device for preventing interference with navigation according to the present invention is lightweight, compact, and energy-efficient, making it suitable for use in unmanned vehicles that are becoming increasingly lightweight. This allows these unmanned vehicles to have the ability to resist interference devices (jamming guns) and effectively accomplish their missions.
[0009] At least the following points will become clear from the description and drawings to be described later. [Brief explanation of the drawings]

[0011] The following describes in detail the preferred embodiments of the present invention, but the present invention is not limited to these, and various modifications are possible within the scope of the description. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present invention.
[0012] First, an embodiment of the present invention will be described in detail with reference to FIGS.
[0013] A communication device for preventing interference with navigation according to one possible embodiment of the present invention is installed on an unmanned vehicle 10. In this embodiment, the unmanned vehicle 10 is an unmanned aerial vehicle, but the present invention is not limited to this and can also be implemented as an unmanned ship, an unmanned vehicle, etc.
[0014] The main feature of the present invention is that the communication device for preventing interference with navigation according to one embodiment of the present invention includes the following components: The components of each component will be described below.
[0015] The 9-axis sensor 20 made of MEMS includes a 3-axis gyroscope 21, a 3-axis magnetometer 22, and a 3-axis gravitational accelerometer 23. In this embodiment, the 9-axis sensor 20 made of MEMS is used and assisted by software calculations to achieve autonomous positioning. Furthermore, the use of MEMS offers advantages such as light weight, small size, and low power consumption.
[0016] An FM video modulator 30 is connected to a camera 31. FM is an analog technology that is on the decline, but it is lightweight, small, and power-efficient, and is capable of modulating images.
[0017] The digital narrowband communication device 40 is electrically connected to the 9-axis sensor 20 and the FM image modulator 30, and is capable of two-way communication and channel control of the FM image modulator 30. Because it only has narrowband communication, it is lightweight, compact, and power-saving, and therefore the present invention employs the digital narrowband communication device 40.
[0018] 2, the present invention may further include a ground center station 50. The ground center station 50 forms an electrical communication connection with a communication device that prevents interference with the navigation of the unmanned vehicle 10.

[0020] As described above, frequency demodulation is achieved during wireless telecommunications, and the original signal is accurately retrieved from the frequency-adjusted carrier wave. In this process, the frequency variations of the input signal are converted into corresponding amplitude variations to reflect the original signal, whether it is voice frequency or data, and then amplified. The FM demodulator 70 device used for this task converts frequency into amplitude variations while ensuring signal fidelity.
[0021] To sum up, the present invention has the following advantages: 1. The communication device for preventing interference with navigation according to the present invention combines (A) a MEMS 9-axis sensor 20, (B) an FM image modulator 30, and (C) a digital narrowband communication device 40. Therefore, the three components (A) + (B) + (C) are configured to complement each other, promoting the effects of weight reduction, miniaturization, and power saving. 2. The communication device for preventing interference with navigation of the present invention is lightweight, small, and energy-efficient, making it suitable for use in unmanned vehicles that are becoming increasingly lightweight. This gives these unmanned vehicles the ability to counter interference devices (jamming guns) and enable them to effectively accomplish their missions.
