On April 30, 2012, two Beidou navigation satellites successfully launched by our country were the first navigation satellites launched by China’s BeiDou satellite navigation system using the “double bow” mode and the first time China adopted the “double bowstar” mode of launching Two earth high orbit satellites. The two satellites launched this time are the twelfth and thirteenth mesh satellites of the BeiDou satellite navigation system. The successful launch of BeiDou Navigation Satellite launched by Beidou Navigation Satellite System is the greatest encouragement and encouragement to all BeiDou people. The launch of these BeiDou navigation satellites has the epoch-making impact on improving and enhancing the navigation and positioning accuracy of the area covered by Beidou Satellite Navigation System significance.
