On the stage of information warfare, time communication plays a corner stone role for joint operations In this paper, the method of time acquisition of war formation based on high precision cellular observation is proposed Through mathematical derivation, the mathematical model of time, the position of the observer and the height of the cellular body can be observed, and the iterative algorithm is used to solve the model Based on this algorithm, the universal time can be observed by observing the height of any cellular body and combining with the existing position information With this method, we are like to have an additional means to obtain accurate time when the timing system is disrupted on the sodium battlefield in the future, which is also the significance of this study, The results show that: The method is effective and independent in the observation time Even for the determination of different cellular bodies, the source of time is unique It can be applied to most combo units of the navy With the advancement of industrialization, the high accuracy of cellular observation will be improved, which will be more conductive to the accurate acquisition of time in this method.
