POV: HOW TO CALCULATE GYRO ERROR BY SUN☀️ (ABC METHOD- UNTIL T/B ONLY) PART 2️⃣! What is the ABC Method? The ABC method is a quick gyro error check using: • Azimuth (true bearing of the Sun) • Bearing (observed gyro bearing) • Correction (gyro error) Formula-wise, it’s simply comparing true azimuth with gyro bearing, but Norie’s Tables help you find the Sun’s true azimuth (A) accurately. ⸻ Data Required Before opening Norie’s Tables, you need: 1. Date 2. GMT of observation 3. Ship’s DR Latitude

Gyro error is the difference between a true bearing and the bearing shown by a gyrocompass. To calculate it, compare the gyro bearing to a known true bearing (e.g., from leading lights or a landmarks). The error is calculated by subtracting the gyro bearing from the true bearing. The error is "west" if the gyro bearing is greater and "east" if it is less. On this examples we can obtain the following given numbers: True Bearing: plotted direction on the chart Gyro Bearing: gyro compass direction

POV: HOW TO CALCULATE GYRO ERROR BY THE SUN ☀️ (UNTIL LHA ONLY) PART 1️⃣ using the Nautical Almanac. Below is the steps: ⸻ 1. Sun’s Declination (Dec) Declination = Sun’s angular distance north or south of the equator Steps: 1. Open the Nautical Almanac 2. Go to the daily pages for the required date 3. Look under SUN 4. Read: • Declination (Dec) for the given hour • d value (change per hour) Apply interpolation: If the time is not exactly on the hour: text{Correction} = d times text{minutes past

Calculating Sun’s Amplitude with Gyro Error Part 2 ⚠️ Important first: Sun’s amplitude itself is always a TRUE direction. Gyro error is applied afterward when comparing with a gyro bearing. So the process has two parts: 1. Calculate Sun’s True Bearing using amplitude 2. Compare it with Gyro Bearing to find Gyro Error ⸻ 1️⃣ Calculate the Sun’s Amplitude (TRUE) Formula (Amplitude): sin A = frac{sin delta}{cos phi} Where: • A = Sun’s amplitude • δ = Sun’s declination (from Nautical Almanac) • φ = O

🟥SUBJECT: GYRO ERROR SAMPLE COMPUTATION Here’s a sample calculation for finding the gyro error. I usually use an Excel calculator for quick results, but it’s also good to review the manual method. Knowing both helps you stay sharp and well-rounded in navigation. =========== Sample calculation (Azimuth-Sun): On 09th of May 2006 at 05h 30m 00s UTC, a vessel in position 55° 00'N & 002° 00'W observed the Sun bearing 073° by magnetic compass. Find the compass error. If variation is 5 W, calculate th
