摘要
物体位置及运动方向测量在武器装备瞄准、卫星通信、深空通信领域具有广泛的用途,物位物移要求为地理信息。利用电子罗盘,直接测量采集到的信息为地磁场信息,即磁方位数据,经过磁偏角修正,得到地理方位数据;利用GPS采集位置信息,通过位置信息、时间信息查询磁偏角,修正状态信息,进而达到准确获知物体位置状态的目的。该装置经过磁偏角信息修正,可以到达电子罗盘方位测量精度。在通过位置信息修正方位信息,得到精确方位数据应用上具有创新性。
The measurement of object's position and movement is used in areas of Aim of weapon,satellite communication and deep space communication.The measurement information requires real earth information.The status information measured by digital compass is the the magnetism of the earth information,it can be revised by declination;The position information collected by GPS is used to search the declination table,then the declination information is acquired.And so we can obtain the accurate AZ data to know the more precise status information.This device can meet the requirement of accuration through the revisement of AZ by the position information collected by GPS.it has the innovation on the aspect of correcting AZ through searching the declination table.
