POV: HOW TO CALCULATE GYRO ERROR BY STAR ⭐️ ANTARES USING ABC METHOD BY NORIES TABLE!

To calculate gyro error by the STAR using the ABC method, you are essentially comparing the observed gyro bearing of the Sun with its true bearing (azimuth).

The ABC method is a quick way to compute the STAR azimuth without full sight reduction tables.

🧭 Step-by-Step Procedure

1. Get Required Data

From your observation:
• Latitude (Lat)
• Declination (Dec) → from Nautical Almanac
• Local Hour Angle (LHA)
• Gyro bearing of the STAR (GB)
Antares.
Use data for ARIES and SHA of Star antares.

2. USE NORIES TABLE BY A,B & C Method

3. CALCULATE AZIMUTH BY QUADRANT TO OBTAIN TRUE BEARING

4. SOLVE THE CORRECTING ANS UNCORRECTING THE COMPASS.
