Marine Navigation - ZIDOTECH ELECTRONICS CO., LTD

Marine Navigation System

A robust inertial technology

ZIDOTECH navigation systems, based on Fiber Optic Gyroscope technology using light spinning in a fiber coil, have no moving parts, ensuring high reliability. Trusted globally for many years, they operate in extreme conditions: subsea and space, proving their robustness and precision.

⁰¹ Lowest cost of ownership

Inertial sensors is usually expensive due to preventive and curative maintenance, FOG-based sensors such as Zidotech’s offer very low cost of ownership due to their high reliability. With a break even advantage of less than 5 years, Zidotech FOG and INS, are highly cost-effective solutions.

The INS is equipped with multiple configurable output ports, supporting protocol management. It can be easily connected via serial or Ethernet interfaces and is compatible with third-party sensors including DVL, GNSS, DMI and barometric altimeters.

All- in-one devices

All our AHRS/INS are all-in-one devices, which means that they can be used in the same time well as for the maritime navigation, but also as an Motion Reference Unit, or for dynamic platform positioning.

Increased Performance through aiding sensors

INS systems offer high autonomy with minimal drift, depending on specifications. Their performance is further enhanced by advanced embedded algorithms that leverage data from aiding sensors (DVL, EM log, GPS, LBL, and depth sensors) to boost accuracy and reject incoherent inputs, ensuring robust navigation.

⁰³ Inertial navigation for subsea operations

Powering robust navigation for ROV and AUV

Equipping over 80% of the subsea vehicles used in the Energy and Geoscience industries, ZIDOTECH FOG-based Inertial Navigation Systems (INS) and Attitude Heading and Reference Systems (AHRS) offer unmatched navigation accuracy for ROVs and AUVs operating in the most demanding environments. Compact, lightweight, and pre-calibrated, they are crucial assets for subsea operators, enhancing operational efficiency in the field.

Unrivaled navigation performance

ZIDOTECH subsea INS provide exceptional accuracy and reliability for ROV and AUV operations in challenging underwater environments, with heading precision of ≥0.01° secLat and optimal navigation down to 6,000 meters.

Ideal for both standard and survey-grade applications, these systems leverage ZIDOTECH advanced Fiber-Optic Gyroscope (FOG) technology for superior performance in dynamic subsea conditions. Performance can be further enhanced with Delph INS post-processing software.

⁰⁵ Fast deployment and alignment

Pre-calibrated and plug-and-play, ZIDOTECH INS enable quick integration without on-field calibration. With self-alignment in motion, they eliminate static alignment time, saving time and costs in offshore operations.

Increased performance and flexibility through INS/DVL coupling

ZIDOTECH INS seamlessly integrate with DVLs offering precise and reliable subsea navigation. This tight coupling combines ZIDOTECH FOG technology with DVL velocity data, improving accuracy, reducing drift, and enhancing stability.

The modular, plug-and-play design lets operators choose the ideal INS/DVL combination based on mission needs, ensuring flexibility and easy integration. This solution simplifies operations while delivering exceptional navigation performance for subsea missions.

⁰⁷ Low power for long deployments

ZIDOTECH latest INS feature low power consumption, enabling long-duration deployments. They are ideal for AUV manufacturers and E-ROV operators seeking to optimize energy use without sacrificing data processing performance.
