Localization Design and Implementation of High Reliability and High Precision Positioning System
In response to the problem of fast,accurate,and efficient positioning and recovery of debris and memory in aircraft flight experiments in the fields of aviation,aerospace,national defense,and military industry,an innovative satellite communica-tion method combining RNSS and RDSS and domestic devices including domestic microcontrollers are used to design a highly reli-able and high-precision nationwide localization system for landing point positioning.After various experiments and applications in complex and harsh environments,the positioning accuracy of the system can be as high as 5 m.The communication frequency of bei-dou short messages is 2 times/min,and the packet loss rate is less than 5%.The large capacity lithium battery can ensure that the system can work continuously for up to 4 hours.It meets the positioning and recycling needs of wreckage and storage,with character-istics such as small size,high accuracy,high reliability,and strong real-time performance.Currently,it has been applied in a cer-tain project.
