Abstract

The 4 m large aperture, 5 degrees field of view and 4000 fibers make LAMOST an important optical spectrum astronomical telescope in the world. It will take a survey observation on about 10,000,000 stars in 20,000 square degrees field of view of north celestial sphere within several years. In order to fully utilize the advantages of a large number of goal optic fibers of LAMOST, carry out the survey observation with better efficiency, and economize valuable astronomical observation time, it is very essential and worthy to make a series of observation plans with utilization ratio of optic fiber as high as possible, which is exactly the scientific goal of Survey Strategy System (SSS) of LAMOST. Various kinds of static and dynamic restraint conditions affecting a survey observation are analyzed and modeled. On the basis of looking for tile with the largest density, the Mean-Shift algorithm is adopted, effectively improving the utilization ratio of optic fiber. With the progress of LAMOST project, new restraints and algorithms will be involved.
