| Abstract: | The communication-navigation system has become a development trend of communication and navigation systems. The joint tactical information division system developed by America is a typical example. The combination and developing of communication and navigation systems is studied in this paper. The working modes and signal characters of JTIDS are analyzed, and the communication and navigation abilities of the JTIDS are discussed. Based on the theory of the error analysis of navigation positioning, the principle of relative navigation and the positioning error are studied thoroughly, moreover, the positioning error fields and working area of the system are presented for the first time here. An important reference is given for developing a communication-navigation system through analyzing and studying. |
