The reason to do so is that the hyperbola intersection model is not a global convergence model, and bad initial coordinate can lead to divergency for the Least Square solutions.

由于双曲线定位算法是非全局收敛的算法，本文提出的基于解析算法用于求解初值可以大大避免系统的发散。

To understand the hyperbolic motion of the probe and give necessary orbit information not only the discrete positions to both ground-base or satellite autonomy device, we studied the variation of hyperbolic orbit and gave the variation equations like that of elliptic orbit.

这段轨道相比其它段虽然很短，但却是实现最终探测目标的关键弧段。为了更好地了解探测器的在这一关键弧段的运行状态，给地面测控系统或是星上自主设备提供必要的轨道信息，而不仅仅是探测器在一些孤立点上的位置和速度，有必要对双曲线轨道及其变化特征进行研究，给出类似于椭圆轨道及其变化的一些基本规律。

The demand curve is thus an equilateral hyperbola.

因此需求曲线是等轴双曲线。
