Because this way of measurement is used conveniently and the accuracy of the result is high, it is still value in the modern battlefield. There are two kinds of measurement methods in the Cape method used in our artillery army. They are respective the sun height method and the sun current angle method. In this article, the two measurement methods are compared from three sections of the homework difficulty, the calculation accuracy and measurable time. At the result, when we make use of the sun to measure directions the sun current angle method should be used as far as possible.
