Position accuracy statistics for different tracking accuracy cases

Tracking accuracy	PU (3D RMS, 3σ)		OD (3D RMS)		Overlap (3D RMS)		OP (3D RMS, 3σ)
	Mean (m)	Std. Dev. (m)	Mean (m)	Std. Dev. (m)	Mean (m)	Std. Dev. (m)	Mean (m)	Std. Dev. (m)
CASE I	35.23	21.46	14.47	15.37	24.31	20.87	76.41	97.50
CASE II	36.23	21.54	18.78	82.92	29.68	37.79	82.92	73.61
CASE III	37.01	22.06	24.73	104.35	38.07	36.43	104.35	90.80

PU, position uncertainty; RMS, root mean square; OD, orbit determination; OP, orbit prediction.
