ECS eCompass Series
The ECS digital compass represents the state-of-the-art in magnetic compassing. It combines a precision 3-axis solid-state magnetometer and a rugged 2-axis electrolytic tilt sensor to provide accurate heading and tilt measurements over a wide range of environmental conditions. The firmware and signal processing algorithms have been refined and improved over three prior generations of compasses to deliver the ultimate in performance from the available sensor data.
ECG eCompass Series
If your compass application involves vibration, acceleration, uneven terrain, or rough seas, the ECG Series, a gyro-stabilized electronic compass, is an uncompromising solution that will outperform rival units that cost more. The ECG provides remarkably accurate heading, pitch, and roll in dynamic conditions. It all starts with a precision 3-axis solid-state magnetometer. Two angular rate gyros independently stabilize pitch and roll. They augment a dual-axis, electrolytic tilt sensor that provides precise tilt measurements in static environments. Two sets of independent filters, one set for pitch and one for roll, combine gyro and electrolytic sensor measurements to provide the best available tilt measurements.
ECL eCompass Series
The ECL low-power digital compass is designed specifically for commercial, industrial, and military users. The ECL series will be of particular interest to ROV and AUV manufacturers who are concerned with power usage and accurate heading in all types of challenging conditions. In standby mode, it draws a mere 50 microamps and requires only 15 mA in run mode. It provides accurate heading data in less than a tenth of a second from wake up. An extended range tilt sensor is available that allows for ±60° of pitch and roll.
ECV eCompass Series
The ECV eCompass Series is a 3D electronic compass providing stable azimuth, pitch, and roll measurements in dynamic conditions. As an enhanced version of our ECG Series, the ECV includes a full suite of precision, 3-axis, MEMS sensors, and an optional dual-axis electrolytic tilt sensor, for the ultimate in near-level accuracy. A high-performance microcontroller orchestrates the fast measurement sequence, sensor calibration adjustments, frame-of-reference translations, trigonometric calculations, and advanced signal processing required to provide accurate heading, pitch, and roll outputs.
