THE ONE-BODY FIX
Embedded Files
If both the azimuth (Zn) and the altitude (Ho) of a celestial body is known, then it is possible to obtain a fix for the “true” position (TP) from observing that one body alone. The spreadsheet one_body_fix.xls solves the navigation triangle in this scenario. The GP is characterized by its declination (cell A2) and Greenwich Hour Angle (B2). The azimuth (Zn) is entered in cell C2, and the observed altitude (Ho) goes into cell D2. The TP coordinates are displayed in row 6.
Summary for spreadsheet one_body_fix.xls:
Input cells: A2, B2, C2, D2
Output cells: A6, B6, C6, D6, E6, F6
The preset data in this spreadsheet define an inverse problem to the one preset in intercept.xls.
