Stable Performance TDF99A Universal Marine Fiber Optic Inertial Navigation System
Introduction
Boasting laser gyros and quartz flexure accelerometers as its core sensing elements, this universal marine laser inertial navigation system (INS) adopts a strapdown inertial navigation architecture. It is equipped with advanced navigation software that runs at high speeds internally, enabling the provision of real-time navigation data. The product range supports a variety of operating modes, including pure inertial navigation, inertial/satellite-integrated navigation, and inertial/velocity-aided integrated navigation. It delivers comprehensive navigation parameters for users' platforms, thus satisfying the demands 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.
