GAO’s Lidar, short for Light Detection and Ranging, is a remote sensing method that employs light in the form of a pulsed laser to measure variable distances to the Earth. It’s akin to radar, but instead of radio waves, it uses light waves. Our Lidar systems consist of three main components: a laser scanner, a GPS receiver, and an inertial measurement unit (IMU). The laser scanner emits rapid pulses of laser light towards the ground, and the sensor measures the time it takes for the light to return after hitting an object or surface. By precisely timing these returns, Lidar systems can generate highly accurate 3D maps of terrain, buildings, vegetation, and other objects. Our Technical professionals utilize Lidar in various fields, including environmental monitoring, urban planning, forestry, archaeology, and autonomous vehicles. Its high resolution and ability to penetrate vegetation make it particularly valuable for creating detailed topographic maps and studying ecosystems. Advancements in GAO Tek Lidar technology have led to the development of compact, lightweight sensors suitable for drones and other unmanned aerial vehicles (UAVs), expanding its applications even further. As our Lidar continues to evolve, it remains a crucial tool for capturing precise spatial data and enabling innovative solutions in numerous industries. 

Depending on their functions and applications Lidar Sensors may also be called: Laser scanners, Laser rangefinders, 3D laser scanners, Laser imaging detection and ranging (LIDAR), Airborne laser scanners (ALS), Terrestrial laser scanners (TLS), Mobile laser scanners, Light imaging, detection, and ranging, Laser altimeters and Laser mapping systems.
