Stable Performance TDF121A Universal Marine Fiber Optic Inertial Navigation System High Reliability


Introduction

This universal marine laser inertial navigation system (INS) incorporates laser gyros and quartz flexure accelerometers as its core sensing devices. It utilizes a strapdown inertial navigation system framework and operates with high-speed internal advanced navigation software to deliver real-time navigation data. The product line supports multiple operational modes, such as purely inertial navigation, inertial/satellite-integrated navigation, and inertial/velocity-aided integrated navigation. It furnishes users with comprehensive navigation parameters for their platforms, thereby meeting the requirements of various 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.
