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.
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.
🚀 Professional-Grade Features:
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.
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's adjustment knobs.
True Night Mode (Red Light): A tactical, all-red interface designed to preserve your dark adaptation and scotopic vision.
True North Calculator: Automatically calculates the exact magnetic declination based on your real-time GPS position.
LST Clock: Displays Local Sidereal Time (LST) in real-time.
GNSS Radar & Sky Plot: Track the signal quality and position of GPS, GLONASS, Galileo, and BeiDou satellites with a built-in Sky Plot and signal histogram.
Barometric Altimeter: Cross-references GPS data with your phone's pressure sensor for highly accurate altitude readings.
Daytime Alignment: Get your mount polar-aligned before dusk or set up perfectly for solar observation.
⚠️ Important Hardware Note:
AstroLock's accuracy depends directly on your device's internal sensors (magnetometer, gyroscope, barometer, and GPS). Phones lacking a native compass sensor will have limited functionality. Always calibrate your phone's compass (figure-8 motion) before your astronomy session!
