Why is Modern Prayer Direction Finding More Reliable Than Traditional Compass?

Magnetic interference issues: - Affected by building steel, electronic devices, etc. - Natural differences in Earth's magnetic field across regions - Case study: Measured deviation of 15-20 degrees in Dubai's skyscraper areas Complex manual calculation: - Requires knowledge of current and Mecca's geographical coordinates - Must understand azimuth calculation principles - Frequent human errors in practical operation Static positioning defects: - Cannot adjust direction in real-time while moving - Frequent recalculations needed during travel - Case study: Cruise passengers need to relocate every 200 meters

Triple positioning technology: - GPS satellite positioning (accuracy within 5 meters) - Inertial navigation system (compensates for temporary GPS failures) - Magnetic compensation algorithm (eliminates local interference) Intelligent calculation system: - Automatic real-time position acquisition - Precise calculation using spherical trigonometry - Built-in global major cities database Dynamic calibration function: - Automatic recalibration every 30 seconds - Automatic compensation in motion state - Real-time direction indicator updates
