The Jewell Instruments ECV Series eCompass, an enhanced version of the ECG Series, includes a full suite of precision, 3-axis, MEMS sensors and an optional dual-axis electrolytic tilt sensor. 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.

Serial outputs from the ECV are compatible with other Jewell eCompass models. These include standard NMEA 0183 HDT, HDG, and XDR sentences, as well as the proprietary HTM ASCII sentence. Advanced binary messages are available at fast data rates for applications requiring additional outputs.

The advanced capabilities of the ECV are supported by updated eCompass PC software that simplifies engineering verification and integration tasks. The software provides the ability to monitor and change compass settings, perform magnetic calibration, capture selected measurement data, and maintain communication and setting logs. Applications: unmanned vehicles, robotics, platform stabilization, excavation machinery.
