Abstract
For the problem that negative time-delay for repeater signal is required sometimes in repeater deception jamming of satellite navigation and realizing negative time-delay is impossible in engineering, adding time-delay correction to all repeater signal channels for compensation is put forward as a solution. Firstly,according to the preset false position and time-delay algorithm of repeater signal,repeater time-de-lay of each satellite signal channel is calculated. Secondly,on the basis of minimization principle of receiver clock-offset,an optimal time-delay correction is selected to add into all repeater signal channels. Theoreti-cal analysis and simulation results indicate that the solution has no effect on positioning results of receiver, and therefore eliminates the limit of negative time-delay to repeater deception jamming.关键词
