Applications

UAV (.) Unmanned Aerial Vehicle, or UAV, is an aircraft that does not require a human to fly and has the ability to automatically control, navigate, and perform tasks. Here are the common types of drones:

1. Multirotor UAV: Usually using four-rotor, six-axis or even eight-rotor rotor, with stable flight, hovering, longitudinal, horizontal, rotation and other functions, suitable for aerial photography, logistics and transportation, rescue and other fields.

2. Fixed-wing UAV: Large wingspan, long-term flight, suitable for long-range aerial survey, traffic monitoring and other fields.

3. VTOL UAV: It can take off and land in the vertical direction, or it can move forward like a fixed-wing UAV to achieve fast movement and flexible operation. For example, the "Global Hawk" of the US Navy.

4. Airship UAV: It is composed of airbags and drive systems including engines, thrusters and servos, and is similar to some similar airships, suitable for meteorological observation, communication and other fields.

5. Portable UAV: Small and lightweight, generally composed of one or several rotors, which can be easily carried, suitable for reconnaissance, monitoring and other fields. The types of drones are diversified, each drone has its own advantages and applicable environment, and with the innovation and development of technology in the future, the drone category will continue to expand and improve.

The application of UAVs in aerial photography, reconnaissance, rescue and other fields is becoming more and more popular, and accurate altitude fixing is one of the indispensable technical means. SDAM laser ranging module is a professional ranging product developed by Seaman Sensing Technology Co., Ltd. for this demand, which can realize the accurate height fixing of UAVs. SDAM laser ranging module is a low-power, high-precision, small-volume ranging module that emits near-infrared light at high frequency, which is installed under the UAV, which can detect the distance information of the ground directly below the radar in real time and feed back to the UAV, so that the UAV can adjust the descent speed or flight altitude in time during the descent process or hovering process.

First of all, the SDAM series laser ranging module adopts high-frequency laser beam scanning technology, which can scan the surrounding objects multiple times in a short time, so as to ensure high accuracy. In addition, the frequency of the sensor can reach up to 250Hz, and the scanning speed is fast, which can adapt to high-speed moving drones.

Secondly, the measurement range of the SDAM laser ranging module can reach 22 meters, which is more suitable for the fixed altitude requirements of the UAV when operating in the air.

Moreover, the measurement error of the sensor is only cm level, which can ensure the safety and accuracy of the drone in the air.

In addition, the small size, light weight, and low price of this sensor make it ideal for use in drones, whether it is a small or large model. In short, the SDAM laser ranging module can achieve accurate and reliable UAV altitude fixing, which will play an important role in UAV applications in the fields of aerial photography, reconnaissance, and rescue.
