SBG Systems Ekinox-M is a motion reference device conceived for deep sea applications functioning at depths down to 6,000 meters. It is equipped with an Inertial Measurement Unit and operates an upgraded Extended Kalman Filter.

Manufacturer focuses on providing high performance at affordable cost. Ekinox-M uses dual antenna GPS to provide heading, attitude, roll and pitch data. It is tested to run well in extreme temperatures. With extended heave in real-time and delayed, it can deliver information from up to four different locations.

MEMs sensors make the unit robust and accurate. Applications in the subsea area include Autonomous Underwater Vehicles and Remotely Operated Vehicles. For marine use, it is ideal for offshore and hydrographic operations in any weather and/or sea conditions.

Ekinox-M comes in a rugged titanium or stainless steel enclosure. Permanent mounting can be on a surface or on the bottom of a boat.
