Mossotti初轨确定方法的推广

Generalization of a method by Mossotti for initial orbit determination

Giovanni F. Gronchi, Giulio Baù, Óscar Rodríguez, Robert Jedicke, Joachim Moeyens

摘要:

在这里,我们回顾了O。F. Mossotti使用四个地心天空平面观测和一个线性方程来计算被观测物体的角动量。然后,我们将该方法扩展到拓扑中心观测,得到角动量的二次方程。两个版本的性能进行了比较,通过数值测试与合成小行星数据使用不同的时间间隔之间的连续观测和不同的天体测量误差。我们还显示了一个比较测试与高斯的方法,使用模拟观测与预期的节奏的VRO-LSST望远镜。

英文摘要:

Here we revisit an initial orbit determination method introduced by O. F. Mossotti employing four geocentric sky-plane observations and a linear equation to compute the angular momentum of the observed body. We then extend the method to topocentric observations, yielding a quadratic equation for the angular momentum. The performance of the two versions are compared through numerical tests with synthetic asteroid data using different time intervals between consecutive observations and different astrometric errors. We also show a comparison test with Gauss's method using simulated observations with the expected cadence of the VRO-LSST telescope.
