摘要
针对飞行过程中的定位问题,设计了一款高功率、体积小的新型定位装置。该定位装置主要由北斗模块、单片机模块和供电模块三部分组成。北斗模块由卫星无线电定位系统和卫星无线电导航系统模块集成,信标工作时首先通过卫星无线电导航系统快速获取定位数据,定位数据经过单片机处理后通过卫星无线电定位系统发送至卫星,然后地面短报文接收机接收到数据,最终传输至上位机,将经度、纬度等参数详细转换并呈现至上位机界面。本设计采用双北斗模块和多接收模块保证发射频率和接收效率。经过连续的测试后,新型定位装置运行状态稳定,通信成功率≥95%,能够达到预期要求。
Aiming at the positioning problem in flight, a new positioning device with high power and small volume is designed. The positioning device is mainly composed of three parts: Beidou module, SCM module and power supply module. Beidou module is integrated with radio determination satellite system and radio navigation satellite system modules.Beacon works through radio navigation satellite system and rapidly access to location data first, after being dealt with the single chip microcomputer the positioning data will be sent to the satellite through radio determination satellite system, then the message receiver will receive the data, finally transfer to first place machine, And then such parameters as latitude and longitude will be converted and rendered to the display interface of the first place machine. This design adopts double Beidou module and multiple receiving module to ensure the transmission frequency and receiving efficiency. After continuous testing, the new positioning device runs stably and the communication success rate is more than 95%,which can meet the expected requirements.
