STEP aims at the nearby earth-alike planets detection  comprehensive research on the planetary system and some astrometry research with 0.5 uas precision in the space  which will get the fruitful achievements in the exo-planetary and astrometry research fields. STEP will take the Space Astrometry technique in the optical band. The FOV is 0.44 degree  based on 1.2m primary and focus length is 50m. The special metrology technique will be taken to reach 0.5 uas astrometry precision  which will be idea for terrestrial exo-planets detection. The mission will take the L2 orbit.
