Abstract
⺠Gaia is a future astrometric mission with high precision astrometry: 0.3-5 mas. ⺠It will enable orbit improvement for NEOs by factor 10-50. ⺠One Gaia data can shrink the uncertainty level and is comparable to ground-based data. ⺠For Apophis, the uncertainty region on the b-plane shrinks well below 1 km. ⺠New objects can be recovered and follow-up network will allow orbital improvement.
