Bathymetric LiDAR System
GEOSTORY Co., Ltd
Our LiDAR uses a custom-designed laser that separates 1064 nm and 532 nm wavelengths from a single source, with two dedicated receivers capturing each set of data independently.
Inside the system, the linear laser beam is refracted at a 10-degree angle through a prism to enable circular scanning. An RF module is also integrated for real-time equipment status monitoring.
From circuit board design to component selection, every part of this system was developed in-house by multiple institutions.
As a result, we have successfully eliminated reliance on foreign technology.

Description
The Pseudo-GNSS system is designed with tightly integrated firmware and hardware.
The firmware generates PRN signals based on GNSS orbital data, modulates them to resemble real GNSS signals, and ensures time synchronization in a Master-Slave structure. A user-friendly GUI software enables easy device control.
The hardware consists of a power unit, signal transmission unit, and communication unit. The power unit ensures stable supply through low-noise design, while the transmission unit radiates GNSS-like signals indoors. The communication unit supports Wi-Fi and wired connections for synchronization and control across multiple devices, with compatibility for smartphones and tablets to display positioning results.
