船の速力誤差などがNNSSの測位計算に及ぼす影響(日本航海学会第45回講演会)

抄録

For position fixing culculations by receiving data obtained from the Navy Navigation Satellite System (NNSS), it is necessaries to input some other data, such as ship's estimated position, ship's speed and antenna height to the data processing computer on board. If the ship's speed and/or the antenna height have some errors, ships position error will be introduced. This paper describes amplitudes of position error resulting from above mentioned erorr sources. These data was obtained from simulation calculations using practical satellite orbit data.
