| Abstract: |
| Through model theory analysis and numerical computation, the positioning capabil
ity of Beidou Satellite Navigation SystemⅡ and its impact on
TT&C ship are discussed. The results show that the positioning accuracy of Beid
ou
Satellite Navigation SystemⅡ is 12 meters more than that of GPS. The relations
hip between ship position accuracy and orientation accuracy is deduced and
the impact of ship position accuracy on lead data and measurement accuracy of
TT&C ship is analysed. It is concluded that in the covering area of Beidou
satellite navigation systemⅡ,the positioning ability meets the demand of TT&C
ship. |
