This is a beacon to help aircraft discover their position 这个闪光灯是帮助飞机确定位置的。
So once we cross - referenced star charts to the horizon , 因此我们可以通过天空星辰座标来确定位置
I ' m running a locate now 我正在确定位置
An array of lasers fitted on the car bumpers , radar and global positioning systems feed data into the on - board computer to determine its location and position 汽车缓冲器上被安装了一排雷射灯,雷达和全球定位系统随时将数据传入车载计算机用以确定位置。
As the position determined , fix 3 points with rope , and iron wire is forbidden , in order to avoid contact accident and self shifting and shaking while operating 确定位置后,应用绳索固定三个点,严禁用铁丝固定,以防发生触点事故和增氧机工作时自动移位和晃动。
Rfid offers exciting application opportunities such as tracking of library books , tracking of patients and equipment in hospitals , airport baggage tracking , and location positioning in fire services training 无线射频标签技术应用范围极广,例如追查图书馆藏书、医院的病人和设备、机场行李,以及在消防训练中确定位置。
The ballistic determination , using the orientation information of the sun , the earth , and the moon , is based on an obvious fact , that is , once the “ moon - missile - earth ” angle and the “ sun - missile - earth ” angle observations are only acquired , also with the known inertial positions of the sun and the moon relative to the earth , the inertial position of the missile will be determined uniquely 弹道导弹利用日、地、月方位信息确定位置信息是基于一个明显的事实:当“月-弹-地”夹角和“日-弹-地”夹角确定时,再加上日、月在地球惯性坐标系下的已知方位,那么导弹的几何位置就唯一确定了。
