Description

Inspection class and light work class ROVs are being asked to do more than ever before. This small, low-cost inertial navigation system (INS) is designed to provide accurate navigation necessary for today’s complicated tasks. With a depth sensor, MEMS inertial measurement unit, and magnetic digital compass, the INSpect GS3 provides a solid navigation solution to support advanced vehicle control features such as station keeping and waypoint following.

Using Greensea's patent-pending OPENSEA software engine, the INSpect GS3 fuses data from available navigation aiding sensors to produce an accurate and stable navigation estimate. The INSpect GS3 supports multiple aiding sensors and is configurable through the Greensea user interface application.
