/**
 * Implements a simplified 2D orbit determination algorithm (e.g., using Gauss's method principles).
 * This is a placeholder for a more robust implementation.
 * For 2D, we can simplify by assuming a circular orbit or using a minimal set of observations.
 *
 * @param r1 - First position vector (2D).
 * @param r2 - Second position vector (2D).
 * @param r3 - Third position vector (2D).
 * @param dt1 - Time difference between r1 and r2.
 * @param dt2 - Time difference between r2 and r3.
 * @returns An estimated OrbitalState (position and velocity) at the time of r2.
