舍入误差积累 accumulation of rounding errors
导线中没有尺度误差积累。
但在实际观测中，这样容易导致误差积累。
In the practical observations, however, this might easily lead to an accumulation of errors.
同时采用陀螺定向系统有效地抑制了导线横向误差积累。
At the same time, the accumulated error of traverse measurement is effectively controlled by use of a gyro orientation system.
