We develop and produce inertial navigation and GNSS/INS systems for equipment manufacturers, system integrators and technical project teams, with product adaptation and application-specific R&D.

RAYSEN NAVIGATION

Company & Engineering Capabilities

RAYSEN NAVIGATION is the navigation brand of Shenzhen Raysen Space Optoelectronic Technology Co., Ltd.. Based in Shenzhen, China, we develop inertial navigation and integrated navigation systems, combining navigation algorithms, error compensation, hardware and software design, testing and calibration.

Our current marine product focus is the iPos MS series. We also undertake product adaptation and application-specific R&D around the required accuracy, operating conditions and integration needs of each platform.

Navigation algorithms & error compensation

Inertial and integrated navigation algorithms, alignment and error compensation for system development.

Hardware & software development

Hardware and software design for inertial navigation systems, including configuration and system integration.

Application-specific R&D

Development around application tasks, target accuracy and operating conditions, with the scope and validation approach defined through feasibility review.

Testing & calibration

Inertial system testing and calibration, supporting error characterisation, compensation and system evaluation.
