- Q127 - Navigation Problems: Oceans
189. On 23 July your 1700 zone time DR position is LAT 27° 29' N, LONG 129° 26' W. You are on course 079° T at a speed of 20 knots. Considering their magnitude, azimuth, and altitude, which group includes the three bodies best suited for a fix at star time?
Spica, Sabik, and Vega are the optimal choice for a three-body fix due to their brightness, well-separated azimuths, and moderate altitudes at the specified date, time, and DR position.
