ZDT-FD511 Fiber Optic Integrated Navigation System

The ZDT-FD511 product is an optical fiber integrated navigation system that internally integrates various sensors such as high-performance optical fiber gyroscopes, accelerometers, and satellite receivers. These sensors are precisely calibrated at the factory to achieve temperature compensation across the full temperature range. The integrated navigation system includes a built-in satellite receiver that supports four types of satellite positioning systems and can operate independently with the Beidou system. It also supports RTK differential positioning, achieving centimeter-level positioning accuracy. Based on a high-performance integrated navigation fusion algorithm, it realizes multi-sensor data fusion and supports the expansion of external sensors such as odometers and DVLs. In the event of satellite signal loss, it can still maintain good navigation data output for a certain period. It is capable of continuously and stably outputting attitude, heading, speed, and position navigation information in various harsh environments.
