GS4 INS Fiber Optic Gyro


 
General 
Product Name:GS4 INS Fiber Optic Gyro
Product 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 high-accuracy depth sensor, high-accuracy fiber optic gyro, and magnetic digital compass, the INSpect GS4 performs – even in difficult inspection environments. Using Greensea’s patent-pending OPENSEA software engine, the INSpect GS4 fuses data from available navigation aiding sensors to produce an accurate and stable navigation estimate. The INSpect GS4 supports up to eight aiding sensors and is configurable through the Greensea user interface application.
