- Q134 - Navigation Problems: Near Coastal
121. On 15 October your 0325 zone time DR position is LAT 26° 51.0' N, LONG 138° 17.0' W. At that time, you observe Canopus bearing 167° pgc. The chronometer reads 00h 25m 36s, and the chronometer error is 00m 20s slow. The variation is 2° E. What is the gyro error?
The gyro error is 1.3 W because the observed gyro bearing (167 pgc) exceeds the true bearing (approximately 165.7 T).
