SunMoonAR V2.0

 

What’s NEW!
Using the GYROSCOPE and a reference to get heading.
The magnetic compass is not precise enough. The error sometimes could reach 30 degree! Thus, using the magnetic compass sometimes gets bad result. ( One undocumented new feature is that the error/accuracy of magnetic compass is now shown)
In contract, the gyroscope is stable and precise, though for a short time. However, to use gyroscope to get heading, a reference is necessary. The sun, the moon, and a custom landmark in sight can be used as reference. Note: if the elevation of sun or the moon is larger than 80 degree, the result won’t be good. The more distant the reference landmark, the more precise the result heading.

Usage:
1.Tap the center bottom, where the HEADING degree resides. Only when the location is available, i.e. GPS is flexed, this function can be used.
