RE: HP49-50G : —>g gravity calculation = g(latitude, height) with WGS84
Please note for the value calculation of k and e² (e squared):
Most Internet sites and official papers or books show inaccurate "ending" digits, as they use too few digits for a truncate value of the axe b (Pole radius). For instance they might give b = 6 356 752.341 or b=6 356 752.3 or b=6 356 752.3412 or b=6 356 752.34125 asf, instead of more digits, something like b=6356752.31424517949756... in order to be able to precess to a more appropriate calculation of k and e² (e squared) after roundings. Regards, Gil . |
