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)
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
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).
