中文摘要：
为提高无人机飞行的距离,设计了利用无线数传模块作为载体的通信系统;该系统分为下位机模块和上位机模块两部分,其中下位机模块主要处理遥控器控制信息和RTCA格式差分GPS信息并提出了一种同时传输这两种信息的数据格式;上位机模块则分别获取这两种信息用于得到高定位精度GPS数据和控制舵机;试飞实验表明,与传统的利用无线电发射机和接收机传输相比,该系统不仅能突破无线电通信距离的限制,还能有效消除外界电磁场对无线电信号的干扰。
英文摘要：
To extend the distance of flight for UAV,communication system using wireless data transmission module as information carrier is designed.The systerm consists of slave module and master module.The function of slave module is to process control data of the remote control and RTCA standard DGPS data,a data format transmitting both the information all together is presented.The master module is used to obtain the information respectively for high precise positioning GPS data and servo control.The flight experiment proves that,compared to the traditional signal transmission with radio transmitter and receiver,this system not only breaks the limit of distance for radio communication,also eliminates disturbance of the electormagnetic fileds on radio signal effectively.
