0-1 sun sensor (LSS) adopts silicon cells as the photosensitive device, used for measuring sun in view field with outputs state value 0 and 1. Single-line and dual-point connection is adopted in 0-1 sun sensor. It can be used for different spacecrafts. Since first flight in Apr., 2009, with trouble-free operation time in-orbit for more than 61 months.
