Abstract: |
In this paper, aimed at measure requirement of hang-staying, slow landing and obstacle-shunning, three kinds of measurement schemes, which are total station, electronic-theodolite and gyro-theodolite, are put forward. For each scheme, the calculating model is educed, the system error of the measurement is analysed, the advantage or disadvantage are evaluated. The best scheme is selected at last. |
