UBD1000 USBL

The UBD-1000 Ultra Short Baseline Underwater Beidou Positioning and Communication System is specifically designed for tethered underwater robots (ROVs) and untethered autonomous underwater vehicles (AUVs). It enables high-precision positioning of underwater targets and stable wireless two-way communication between surface and

underwater.

Utilizing state-of-the-art broadband spread spectrum technology and target tracking algorithms, this product can perform real-time positioning, tracking, and communication for multiple underwater targets simultaneously, building a multi-node underwater stereoscopic positioning and communication network for users. The multipath effect suppression algorithm, developed for(adverse water conditions) in shallow water, significantly overcomes positioning drift of

underwater targets and improves positioning efficiency. The anti-Doppler effect compensation algorithm allows stable positioning and communication for surface/underwater platforms (e.g., AUVs) during high-speed dynamic navigation. It also features small size, light weight, and high integration, making it particularly suitable for installation on underwater vehicles with limited space, as well as for diver-held navigation sonar platforms.

Note 1: Effective Positioning Rate refers to the ratio of [number of valid positioning points] to [total

number of positioning points] after removing abnormal positioning points within a unit time.
