Detailed Description

Convert planet orbiting initial conditions to heliocentric coordinates using spice.

Adding this model to your rigid body spacecraft allows you to specify the vehicle initial state in the planet orbit frame rather than the ECI frame. The position, velocity, quaternion, and bodyRate initial values are all overwritten after being converted.

This module has outlets which must be connected to the SPICE model.
