| Abstract: | Besides an introduction to the vertical angular velocity turntable scheme, two kinds of new north seeking schemes are put forward in order to enhance the north seeking accuracy to a great extent, i.e. the horizontal angular velocity turntable scheme and the vertical sinusoidal linear velocity mechanism scheme, and their mathematical models are given, their data processes are expounded in detail, then the advantages and disadvantages of these three kinds of north seeking system are compared with one another and indicates that the north seeking accuracy of the last two kinds of schemes are improved a lots. |
