Hello!
Please correct me if I'm wrong. I understood this problem as:
- 1981-11-13T11:12:00; GHASun=351°55.4', DecSun=-18°0.3'; Zenith Distance observed = 1°52'
- 1981-11-13T11:21:00; GHASun=354°10.4', DecSun=-18°0.4'; Zenith Distance observed = 1°26.1'
- Course 164°; speed 12kn
From these observations I got a fix: 19°14.8'S, 6°37.4'E on 1981-11-13T11:21:00. Or, if the speed and course remain the same, on 1981-11-13T12:00:00 the position would be 19°22.1'S, 6°39.6'E.
How far is it from truth?
