Abstract
We present here a conceptual design of a near infrared survey satellite whose primary goal is to carry out an all sky survey of Polycyclic Aromatic Hydrocarbons (PAH). The searching of PAH is through direct imaging both at and besides its 3.3 μm CH stretching vibrations emission bands and make comparison between the "line" and the continuum fluxes. The dawn-dust sun-synchronous orbit is chosen because it is ideal for thermal control and it is suitable for all sky surveys. The "pointing-maneuver-pointing" observing strategy is adopted in order to minimize the effect from the detector read noises. The survey sensitivity is chosen to generally match those of the UKIDSS near IR surveys so their results can be compared more directly.
