Frontiers of Information Technology & Electronic Engineering 2021, Volume 22, Issue 2, Pages 141-286 doi: 10.1631/FITEE.1900358

Abstract: s are widely used in attitude-determination and control systems of satellites. The main deficiency of static s is the requirement of a small field of view (FOV). A typical FOV for a static is about 20° to 30°, which may not be sufficient for low-Earth-orbiting s. A novel compact with an FOV of nearly 180° is developed here. The Earth sensor comprises a panoramic annular lens (PAL) and an off-the-shelf camera with an uncooled complementary-metal-oxide-semiconductor (CMOS) infrared sensor. PAL is used to augment FOV so as to obtain a complete infrared image of the Earth from low-Earth-orbit. An algorithm is developed to compensate for the distortion caused by PAL and to calculate the vector of the Earth. The new is compact with low power consumption and high precision. Simulated images and on-orbit infrared images obtained via the ZDPS-2 are used to assess the performance of the new . Experiments show that the accuracy of the Earth sensor is about 0.032°.
