The other is quicker, but its accuracy is unsatisfied because the simplified model of high precision trajectory is used.

一类速度很快 ，但因为使用的是简化模型 ，因而精度较差 ，难以满足未来高精度测控的需要。

The traditional passive location method is cross positioning. But its accuracy is too low to fulfil practical requirement.

传统的无源定位方法大都采用多个接收机测向，交叉定位，但其测向精度低，难以满足实际需求。

For now, the researchers have created an eight-electrode proof-of-concept bracelet, but its accuracy leaves something to be desired -- it correctly identifies its wearer only 80 to 90 percent of the time, whereas fingerprint recognition has a failure rate of less than 1 in 1, 000.
