Product Description
TDF121A Universal Marine Fiber Optic Inertial Navigation System
High reliability marine inertial navigation system with stable performance for demanding maritime applications.
Product Overview
This universal marine laser inertial navigation system (INS) incorporates laser gyros and quartz flexure accelerometers as core sensing devices. Utilizing a strapdown inertial navigation system framework with high-speed internal advanced navigation software, it delivers real-time navigation data. The system supports multiple operational modes including purely inertial navigation, inertial/satellite-integrated navigation, and inertial/velocity-aided integrated navigation.
Applications
Ideal for small- and medium-sized unmanned surface vessels (USVs), unmanned underwater vehicles (UUVs), underwater guided weapons, and platforms operating in complex environments with high speeds, wide temperature variations, and strong vibrations.
Key Features
- Capable of alignment and initialization while moored or during constant-speed straight-line navigation
- Stable performance and high reliability
- System fault detection and alarm functions
- Digital output interfaces including Ethernet and RS422 serial ports
