Product Description

The system has a combined inertial/satellite navigation mode and a pure inertial mode.
The satellites that can be received by the GNSS receiver in the inertial/satellite integrated navigation mode satellite positioning information for combined navigation; output inertial solution position after losing signal speed attitude, with meter-level positioning accuracy in a short time.
After the pure inertia mode is started, it has the function of accurate attitude measurement and can output pitch rolling and heading, pure inertia can statically seek north.

JIOPTICS installation of fiber optic gyroscope to provide ease of integration flexibility, and our developers toolkit to rapid prototyping, not only meet the specification requirements, also provide high-quality performance meet the demand of end users.
