Product Description
High Reliability Model TDF71A Universal Marine Fiber Optic Inertial Navigation System
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.
Application Scope
Suitable for small- and medium-sized unmanned surface vessels (USVs), unmanned underwater vehicles (UUVs), underwater guided weapons, and other platforms operating in complex environments with high speeds, wide temperature variations, and strong vibrations.
Key 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
