Once he has the ball, it needs to be crowbarred off him, he has the acceleration to escape orbit and has scored nearly 50 goals for Barcelona this season as he led them to the Liga title.
The acceleration may in turn be obtained from the velocity of the satellite and the radius of the orbit.
这个加速度又可根据卫星的速度和它的轨道半径来求得。

Secondly, the GPS satellite circulating orbit is simulated, according to the position, speed, acceleration and the rate action factor of acceleration, given by GPS satellite broadcast star calendar.
