摘　　要：超紧致GPS/惯性耦合技术将传统的GPS伪距计算与相关过程进行紧耦合,提高了对接收的GPS信号保持锁定的能力。与传统的跟踪环路相比,超紧致的方法可以近实时地处理数据,因此具有更好的抗干扰能力和导航精度。最后给出了这种技术的干扰对抗措施。The ultratight method couples tightly conventional GPS pseudo-range computation in the correlation process. It improves the ability to maintain tracking lock upon the received GPS signals. Compared with the traditional technique, it provides a higher degree of robustness and immunity to interferences. It can process data in real time nearly. Finally the counterpart-measures are presented.
