多被动传感器测向交叉定位精度与传感器之间协同信息的传输距离（基线长度）直接相关。被动传感器实施测向交叉定位时的基线长度较短将导致定位精度不高，无法满足武器打击的目指精度要求。针对此问题，提出了基于北斗短报文的测向交叉定位协同信息远程传输方案，并对其技术可行性和实现方法进行了研究。该方案能够极大地延长基线长度，显著提高多被动传感器的测向交叉定位精度。
多被動傳感器測嚮交扠定位精度與傳感器之間協同信息的傳輸距離（基線長度）直接相關。被動傳感器實施測嚮交扠定位時的基線長度較短將導緻定位精度不高，無法滿足武器打擊的目指精度要求。針對此問題，提齣瞭基于北鬥短報文的測嚮交扠定位協同信息遠程傳輸方案，併對其技術可行性和實現方法進行瞭研究。該方案能夠極大地延長基線長度，顯著提高多被動傳感器的測嚮交扠定位精度。

Positioning accuracy of the bearing-only location system with multiple passive sensors is closely related to the transmission distance(baseline length)of cooperative information between the passive sensors. If the baseline length of the bearing-only location system with multiple passive sensors is short,the positioning accuracy will be too low to meet the requirement of the target indication accuracy for weapon attacking. The cooperative information remote transmission scheme based on the Bei-dou short-message communication isproposed to solve this problem. Its technical feasibility and implementation method is re-searched. The scheme can greatly increase the baseline length,and significantly improve the positioning accuracy for the bearing-only location system with multiple passive sensors.
