Caption

Yellow represents BVs, purple represents SVs, and blue represents O-CNOPs. The notation Eijk (i=1, 2, 3; j=1, 2, 3; k=1, 2, 3) represents the accuracy category defined by the ith error bound for turning location (i.e., 60km, 120km, 180km), jth error bound for turning time (i.e., 6h, 12h, 18h), and kth error bound for turning angle (i.e., 5°, 10°, 15°).
