Stable Performance Model TDF61A Universal Marine Fiber Optic Inertial Navigation System High Reliability
Introduction
This universal marine laser inertial navigation system (INS) uses laser gyros and quartz flexure accelerometers as its core sensors, employing a strapdown inertial navigation system architecture and running advanced navigation software internally at high speed to provide real-time navigation information. The product series supports multiple operating modes, including purely inertial navigation, inertial/satellite-based integrated navigation, and inertial/velocity-aided integrated navigation, providing users with complete navigation parameters for their platforms, meeting the needs of various types of marine platforms.
Application
Suitable for small- and medium-sized unmanned surface vessels (USVs), unmanned underwater vehicles (UUVs), underwater guided weapons, etc., especially platforms operating in complex environments with high speeds, wide temperature variations, and strong vibrations.
Characteristics
♦ Capable of alignment and initialization while moored or during constant-speed straight-line navigation.
♦ Stable performance and high reliability.
♦ Features system fault detection and alarm functions.
♦ Equipped with digital output interfaces, including Ethernet and RS422 serial ports.
