AL16
Laser RTK GNSS Receiver
The A&I AL16 is a laser IMU-RTK GNSS receiver that integrates with high-quality camera. With IMU-based self-initializaiton, laser meticulous calibration technology and 13 megapixel camera, it is capable of performing highly accurate non-contact measurements in environments with obstructions and areas that are difficult to reach using a traditional centering pole. Furthermore, with AR technology, it helps to significantly enhance the stakeout efficiency.
Features
Laser Measurement with High-quality Camera Assistance
- Millimeter-level laser combined with a high-precision IMU delivers 2.5cm accuracy in complex environments, providing a robust high precision GNSSreceiver solution.
- 13MP camera with software crosshairs enables effortless, long-range targeting to streamline advanced RTK GNSS receiver
Tilt Measurement
- High-precision IMU auto-calibrates during regular motion, enabling immediate initialization for demanding RTK receiver applications
- Precision indicators ensure each measurement is free from ‘drifting’. It achieves a measurement precision of 2cm within 60° tilt.
AR Stakeout
- Augmented reality on software helps surveyor easily find the exact location of stakeout points.
- Avoid the forth and back movement of centering pole in traditional way, the stakeout efficiency is improved by 50%, especially for beginner surveyor.
Full Connectivity
- Built-in 2W transceiver module supporting multiple protocols. Under LoRa technology, the communication range can reach up to 5 kilometers ( depending on the environment).
- It integrates global 2G/3G/4G, WIFI, Bluetooth, and NFC.
Balancing Design
Just the right balance between size, weight, endurance and GNSS antenna performance, optimized for geodetic GNSS receiver standards in a compact GNSS receiver form factor
Applications
