The UWGNSSR1 Deep-Sea Pressure-Resistant GNSS High-Precision Positioning Equipment is composed of three parts: an antenna, a GNSS module, and a watertight cable assembly. The GNSS antenna supports three satellite systems and six frequency points; the GNSS module is equipped with a high-precision positioning function, with a positioning accuracy of within 5 meters (PDOP ≤ 4). It supports the B2B-PPP mode, and after the function is activated, the positioning accuracy can reach 30 centimeters after 30 minutes.
