摘　　要：充分利用运动目标的数学模型,通过参数简化和差分编码方法进行数据压缩,提高了数据传输效率。基于北斗报文服务和监视任务的特点,提出了一种分布传输方法,在不增加冗余信息的基础上,提高了系统抗突发干扰的能力,增强了传输过程的可靠性。仿真和实测结果表明,该设计方案在保证数据传输可靠性的基础上,数据压缩效率达到了89%。Taking full advantage of the mathematical model of moving targets, to compress data and enhance transmission efficiency by simplifying parameters and differential encoding. A new distributed transmission method is proposed based on the characteristics of compass message services and monitoring tasks, which improves both the system capability of anti-burst interference and the reliability of transmission processes. Simulation and experimental results show that this design could improve the compression efficiency to 89% while ensuring the reliability of data transmission.
