Design and implementation of the telemetry and remote control system of the high altitude balloon based on iridium in Antarctic

摘要:

根据我国第38次南极科考的高空气球飞行试验任务的科学目标需求,结合南极保障条件现状,设计了用于南极科考高空气球系统的测控系统,采用了铱星短报文通信模块9602作为基础测控通信通道,IP数据通信终端Pilot作为有效载荷数据通信通道,同时利用Pilot终端带宽余量,设计了一条备用的测控通信通道,实现了双路冗余测控,提高了测控通信的可靠性。在内陆的数据传输测试试验中,两条测控通道数据传输正常,载荷数据下行传输速率在115-120kbps之间,达到了预期指标,在完成环境适应性改造之后,可以用于保障第38次南极科考的高空气球飞行试验任务顺利进行。

Abstract:

According to the scientific target requirements of the 38th Antarctic scientific expedition high altitude balloon flight test mission in China, combined with the current situation of the Antarctic support conditions, a telemetry and remote control system for the high altitude balloon system of the Antarctic scientific expedition is designed. The iridium short message communication module 9602 is used as the basic measurement and control communication channel, the IP data communication terminal Pilot is used as the payload data communication channel, and the Pilot terminal is used at the same time With wide margin, a spare telemetry and remote control channel is designed to realize dual redundant measurement and control and improve the reliability of measurement and control communication. In the inland data transmission test, the data transmission of the two measurement and control channels is normal, and the downward transmission rate of load data is between 115-120kbps, which has reached the expected target. After the completion of the environmental adaptability transformation, it can be used to ensure the smooth progress of the 38th Antarctic scientific expedition high altitude balloon flight test task.
