PS1 is essentially one quarter of Pan-STARRS, and has been built to test many of the features of the full PS4 telescope.
PS1 allows us to test all the technology that is being developed for Pan-STARRS, including the telescope design, the cameras and the data reduction software.
PS1 will be used to make a full-sky survey that will provide astrometric and photometric calibration data that will be used for the full Pan-STARRS survey.
