HYINS02 FOG Inertial Navigation System

Complete data output &high-precision time synchronization

● Self north-finding integrated navigation delivers a complete set of inertial parameters including heading,roll,pitch,

position,velocity,heave,sway and surge.

●Proprietary inertial navigation algorithm ensures uninterrupted and distortion-free data even in GNSS-denied complex marine environments(e.g.,under bridges,near islands/reefs)with a continuous heading accuracy of ≤0.1°seco(RMS).

●High-precision time sync features nanosecond-level measurement latency and provides three synchronous output pulses to guarantee temporal consistency for multi-device collaborative surveys.

Easy integration

● Built-in GPS module supports single-point,RTK,Beidou PPP positioning,and compatible with external GPS/Beidou.

● 32GB internal storage for recording all inertial data and post-processing.

● 1xUSB port for direct data reading and 1x10/100M Ethernet port for remote data access.

● Light indicators for GPS lock and POWER.

● Versatile output interfaces:providing four serial ports,each of which can be software-configured to switch between RS232/RS422 online,ensuring compatibility with mainstream equipment like multi-beam sonars and DVLs.

● Embedded IE interface makes parameter configuration intuitive and efficient.

Reliable and prominent performance

● Military-grade R&D and production standards,reliable and excellent performance.

The HYINS02 is a new multi-functional fiber optic inertial navigation system specifically engineered for offshore platforms. Integrated high-precision fiber optic  gyroscopes and quartz accelerometers, with proprietary  technologies such as self north-finding, inertial navigation and integrated navigation algorithms, it provides  real-time, high-accuracy output of comprehensive inertial data, including heading, position, velocity, attitude,  angular rate, acceleration, and time synchronization. It  delivers stable, precise, and reliable measurement support for a wide range of maritime applications, such as  offshore navigation, marine surveying and mapping, and  ocean engineering.
