Ellipse-A is a small-sized high performance Attitude and Heading Reference System (AHRS). It provides Roll, Pitch, Heading, and Heave data. This light-weight sensor (45 grams) includes a MEMS-based Inertial Measurement Unit (IMU) integrating three gyroscopes, three magnetometers, and three accelerometers. High Accuracy for Such a Small Sensor: 0.1° Roll and Pitch over 360° 0.8° Heading (Internal Magnetometers) 5 cm Real-time Heave, adjusted to the wave period (Marine applications) Key features: Very Low Noise Gyroscopes 64-bit architecture for high end filtering processing IP 68 Enclosure 200 Hz Output Rate RS-232, RS-422, and CAN Interfaces Binary, NMEA, ASCII, and TSS Protocols 2 years warranty Marine Ellipse-A is the smallest inertial sensor of its class to provide heave data accurate to 5cm. Mounted on a buoy or a vessel, it adjusts automatically to the wave period for more accurate measurements. It is also perfectly suited to subsea applications to compensate single beam sonar or to orientate Remotely Operated Vehicles (ROV).
