Model TDF62A Universal Marine Fiber Optic Inertial Navigation System Stable Performance
Introduction
This universal marine laser inertial navigation system (INS) features laser gyros and quartz flexure accelerometers as its core sensing components. Adopting a strapdown inertial navigation system architecture, it is equipped with advanced navigation software that operates at high speed internally to deliver real-time navigation data.
The product lineup offers multiple 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, effectively catering to the requirements of diverse 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.
