High Reliability Model TDF71A Universal Marine Fiber Optic Inertial Navigation System
Introduction
This all-purpose marine laser inertial navigation system (INS) features laser gyros and quartz flexure accelerometers as its core sensing components. Adopting a strapdown inertial navigation system structure, it incorporates advanced navigation software that operates at high speeds internally to deliver real-time navigation data. The product lineup offers a variety of operational modes, such as standalone inertial navigation, inertial/satellite-integrated navigation, and inertial/velocity-aided integrated navigation. It supplies users with comprehensive navigation parameters for their platforms, catering to the requirements of diverse marine vessel types.
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.
