## Description

Make your stargazing and astrophotography sessions easier with AstroLock! Designed for amateur and professional astronomers, our app turns your smartphone into an advanced, high-precision tool for aligning your telescope and equatorial mount.<br><br>Forget compasses that go crazy near metal or struggling in the dark. AstroLock combines advanced sensors, aerospace-grade filters (Kalman/ZUPT), and GNSS data to deliver absolute precision.<br><br>🚀 Professional-Grade Features:<br><br>INS Lock (Inertial Navigation System): The system locks the magnetic reference and relies on the gyroscope, completely ignoring magnetic interference from your heavy metal telescope mount.<br><br>Audio Tracking Feedback (Sonar): Align without looking at your screen! Dynamic audio beeps guide you, speeding up as you get closer to True North/South, letting you keep your eyes on the mount&#39;s adjustment knobs.<br><br>True Night Mode (Red Light): A tactical, all-red interface designed to preserve your dark adaptation and scotopic vision.<br><br>True North Calculator: Automatically calculates the exact magnetic declination based on your real-time GPS position.<br><br>LST Clock: Displays Local Sidereal Time (LST) in real-time.<br><br>GNSS Radar &amp; Sky Plot: Track the signal quality and position of GPS, GLONASS, Galileo, and BeiDou satellites with a built-in Sky Plot and signal histogram.<br><br>Barometric Altimeter: Cross-references GPS data with your phone&#39;s pressure sensor for highly accurate altitude readings.<br><br>Daytime Alignment: Get your mount polar-aligned before dusk or set up perfectly for solar observation.<br><br>⚠️ Important Hardware Note:<br>AstroLock&#39;s accuracy depends directly on your device&#39;s internal sensors (magnetometer, gyroscope, barometer, and GPS). Phones lacking a native compass sensor will have limited functionality. Always calibrate your phone&#39;s compass (figure-8 motion) before your astronomy session!<br><br>Download now and lock your sights on the stars with AstroLock!
