An E-Compass (Electronic Compass) is a digital navigation tool that determines direction based on the Earth's magnetic field. Unlike traditional magnetic compasses, an E-Compass integrates magnetometers, accelerometers, and gyroscopes to provide accurate and stable orientation data in digital devices.

How E-Compass Works
An E-Compass operates by using:

Magnetometers – Detect Earth's magnetic field to determine cardinal directions.

Accelerometers – Measure tilt and motion to correct orientation errors.

Gyroscopes – Improve stability and accuracy in movement-based applications.

By combining these sensors, an E-Compass can adjust for tilt, motion, and interference, ensuring reliable directional readings.

Applications of E-Compass
1. Smartphones & Tablets
Enables GPS-based navigation by providing accurate heading information.

Supports augmented reality (AR) applications like digital compasses and star maps.

2. Wearable Devices & Smartwatches
Assists in fitness tracking, outdoor sports, and hiking by guiding users through terrain.

3. Automotive & Aviation
Enhances GPS navigation and driver assistance systems.

Used in aircraft for accurate altitude and heading detection.
