On 3 February your 0451 zone time DR position is LAT 24°15.0' S, LONG 124°24.0' W. Considering their magnitude, azimuth and altitude, which group includes the three bodies best suited for a fix at star time?

Question

On 3 February your 0451 zone time DR position is LAT 24&deg;15.0' S, LONG 124&deg;24.0' W. Considering their magnitude, azimuth and altitude, which group includes the three bodies best suited for a fix at star time?

Accepted Answer

Option C: Alphard, Denebola, Acrux. Optimal star fixes require bodies separated by approximately 120° in azimuth with altitudes between 15° and 75°. Alphard, Denebola, and Acrux provide the necessary geometric distribution and brightness for a reliable fix at the specified date and time, minimizing the potential for intercept errors in the celestial plot.
