1) Ephemeris (almanac data), Venus GP on 2014 May 5 at 13h 15m 18s (p. 256):
UT: 2014 May 5, 13:15:18
GHA = 58º 58.0’
Dec = S 0º 14.1’
2) Sextant altitude corrections (Venus, p. 259)
Input: Hs = 4º 32.6’
Output: Ho = 4º 17.6’
3) The calculated altitude and azimuth (pp. 279-280)
GP: GHA = 53º Dec = S 15º
AP: Lat = N 32º Long = W 16º
to which we add Ho = 30º 30.0’ in order to allow the calculation of the intercept and the plotting of the LOP.
The resulting LOP (intercept 38 NM away, azimuth 223) is plotted with the T-Plotter.
As it was also calculated by intercept.xls this LOP crosses:
the AP’s meridian at 52 NM north of the AP
the AP’s parallel at 56 NM east of the AP
