Influence of the Choice of Lunar Gravity Model on Orbit Determination for Lunar Orbiters

Table 5

Orbit propagation (OP) differences between true orbit dynamics and OD dynamics.

	Propagated orbit difference (m, RMS)
	Radial (min./max.)	In-track (min./max.)	Cross-track (min./max.)
Position	7.86 (−14.31/15.36)	73.53 (−140.99/22.14)	3.07 (−7.52/8.56)
Velocity	6.41 (−1.04/11.35)	0.70 (−1.35/1.29)	0.27 (−0.70/0.78)
