SAPRE Upload
Model API name: sapre_upload
The SPENVIS orbit generator computes trajectory osculatory orbital elements using a numerical Runge-Kutta integration method. The independent variable is the eccentric anomaly. Osculatory elements are computed at constant equidistant eccentric anomaly steps. Orbits around three planets are currenly available.
