基于载波相位三差的航天器GPS/INS组合姿态算法-Based on carrier phase III spacecraft poor GPS/INS Attitude Algorithm portfolio

The dynamics of orbit uncertainty in an unstable orbital environment are discussed with specific application to the orbit determination of a halo orbit about the Earth{Sun L1 point. This article documents a simplified orbit determination covari

Synthetic aperture radar (SAR) is a form of radar which is used to create images of objects, such as landscapes – these images can be either two or three dimensional representations of the object. SAR uses the motion of the radar antenna over a targe
