    Long-distance and high-precision range and attitude measurements are key technologies in fields such as aerospace remote sensing, target recognition, and navigation control. Here, we theoretically and experimentally study the second-order correlations of the thermal light field for deep Fresnel-zone ranging, and we achieve a precision of 0.5 mm. In addition, we demonstrate with a proof-of-principle simulation experiment that this ranging method can be utilized to measure the target attitude. This method, which can achieve high-precision range measurements over long distances, can be used as a supplement to traditional laser-ranging technology. This method can employ natural light sources such as stars light to measure distance and attitude, and has less demand for energy and other resources. It can provide a new solution for satellite positioning and other space ranging needs.
